AC Unit Not Turning On - How to Fix It Step by Step

Is your AC unit not turning on? Or maybe it's running but not cooling? This video walks you through a lot of the common fixes while explaining how it all works. We suggest watching the whole video so that you can understand the big picture of how your AC works and be able to figure out why your AC is not working on your own. But if you are looking for a walkthrough on something specific, here is a timetable you can use:

I’m a woman who lives alone and have no money to call in a service person. Thanks to you and your videos, I just fixed my central air. It was the plunger on the contactor I may have to replace the part but I think it’s not too expensive.

[@tonyupsman]

Ever since KZbin became what it is today there is nothing that I won't consider fixing on my own. I didn't have a clue about working with my hands or what was needed to tackle these things. These videos that these industry leading people put out have saved me so much money it is unbelieveable. I watch my parents get ripped off into my young audult life by contractors who took advantage of them not knowing how knowing what is fair and what is actual highway robbery. I'm 51 and the last 15 years I went from being an average Joe to the extended family and friends Plumber, Journeyman Electrician, Light AC Repair, Auto Mechanic for things that would have cost me thousands and I was able to do it for under 20 or 30 bucks! Appliance Maintenance and Repair. Washing Machine (5 times), Gas Dryer (3 Times), Thermostat Replacement, Gas Water Heater Maintenance and Replacement (2 Times), Big Screen TVs that cost thousands of dollars totally repaired for a couple bucks replacement of computer control board capacitors, Kitchen Sink Replacement, Reverse Osmosis Overhaul Better Water Tubing and placement for stronger pressure to fridge ice machines and water dispenser, Kirby Vaccuum Rescued from death 5 times over the years, Expensive High Quality Wet Vaccuum parts fixed or replaced, I refinished our oak front doors quite literally stripped off the old lacquer and stain and sanded them and made them better than when we bought the house, Installed 5 Ceiling Fans, I could go on and on.... This monkey see / monkey do approach by using a tablet to play videos in step by step by guys like this seriously has made these expert procedures totally safe, fast and so low cost. I tip my hat and recognize their efforts and turning me into a one man army of tradesmen doing work that amazes even me. KUDOS! -Tony Cusimano

You just saved me having to call a technician. My girlfriend and I just bought a house and when our AC was on, the vents were blowing air but my house was only getting warmer. With your video I was able to trace the issue to the wiring in my thermostat and I rewired it. Idk how the previous owners lived without AC, but thanks to you I won't have to share that experience.

This guy is the best. I have saved thousands by following his video suggestions. I wish I could buy him a beer or dinner! Saved my AC and heating at least 5x now.

[@funwithmaddox23]

When I turn on my AC through my thermostat nothing is happening I went up into my attic and nothing happens there I went outside to my AC unit and nothing happens there either. I did pull the panel to my AC unit and pushed in the plunger which did start the ac unit but it shuts off as soon as I let go. Does the thermostat talk to the ac unit first or does it go to the furnace first?

[@funwithmaddox23]

I replaced my capacitor 2 years ago by the way. At that time I had the humming but after changing the capacitor it worked just fine.

[@Steveambriz]

@@funwithmaddox23 sounds like you’re not getting 24v to the contactor. Something in the circuit is open, I would look for a tripped float switch or maybe a tripped high pressure switch on the freon line.

Thanks so much for this video! A few years ago my circuit breaker and transformer blew out in a powerful storm. This video helped me tremendously. To the extent I could have a conversation with a friend's husband who runs an HVAC business and he helped me step through the multiple problems and then walked me through fixing it and gave me a free transformer. I learned a lot. Just now though the thermostat was running, but the house was 3 degrees warmer and getting warmer. I checked all the stuff inside the house and finally went to the compressor. The compressor was hot as I approached it. The thermostat asked it to turn on, but the fan blades moved barely. Then the poor thing gave up. I got a stick and waited for the next round and I helped the blades just a bit and the whole thing came to life. What a joy! Slowly, the compressor cooled down with all that air circulating. I'm standing on a chair under the vent enjoying a wonderful cool breeze grateful. Thank you!!

[@studiopvt1783]

Tied for "Firstly, I'd like to say"... the walk-through on possible problem points was totally on-point...tied for "firstly" is why would anyone give a negative. I have an AC unit that blows air but the outside unit doesn't do anything. No hum, no noise, no fan. Breaker looks good, so it must be outside. I learned from this video how to check for electrical issues in a CAREFUL way. The system is old but I have a desire to check it before jumping in to replace the whole thing (especially with the financial situation effecting us all). Even if it needs to be replaced, I can speak with the estimator on a more educated level about AC units. I truly appreciate this video and I will use what I learned to do my own troubleshooting BEFORE jumping the gun to get everything replaced. If, after, the basic checks deem the repair beyond my abilities, I will call upon a professional to do the work. YOU are an honest professional.

This video was a life saver for me. I went to turn my furnace on for the first time last week. Absolutely nothing happened. I found my new puppy had chewed the wires outside. I cut out the chewed section and put them back together. Still nothing. I found this video and discovered the 5 amp fuse on the circuit board. I had no idea there was a fuse on there and thought they were all in the main fuse box. Just like in the video, it took me a bit to even find it. $3 later for a 5 pack of fuses and it kicked right on! Thank you so much!!

Thank you so much for this video. I knew that I had an issue with my condenser unit but I had no idea how to trace the issue, let alone prevent myself from getting electrocuted. You taught me how to safely remove the side panel. That’s when I learned that I had not 1, not 2, but 3 dead rats in my unit! One of them was preventing the plunger switch from completing the circuit. I was able to remove the fellas and get my AC working again. You’re the man!

[@drunkkajun]

This video put me on the right track with the 3 amp fuse. Dig deeper and found a bad chip on the circuit board. Bought parts and was a 30 minute fix. This guy is a great teacher and saved me a few hundred bucks I am sure.

[@dancook188]

drunkkajun I think my problem is similar to your experience - how did you determine which control board components were bad? Our red LED light power indicator on the board does not light up and the fuse is NOT blown. So it seems power is not getting to the board OR something in the board may be burned up/malfunctioning, hence not allowing the LED to receive power meaning nothing else can work in the system. Just don’t know what that problem is! We recently were struck by lightning and several days later, our downstairs HVAC system stopped working. I’ve checked all breaker switches as well (even turned off/on for good measure). Please let me know if you have a suggestion for how to narrow down why the circuit/control board isn’t getting power. -Dan

[@anthonybello9359]

I just wanted to say thanks so much! Because of your troubleshooting videos? I was able to rebuild a dead 3 ton, & 1.5 ton unit that went down on us. The company we hired to give us an estimate on the 1.5 ton quoted us at $2,700 for a whole new unit because he said the compressor was dead. After watching your videos? I was able to fix the problem & get the system up & running for $9.37 for the new wire terminals that had to be installed on the compressor wiring harness. A moth decided to nest under the cover of the compressor access area, which arched out the wires & there was no continuity traveling from the wires of the capacitor, or connector to the compressor. You showed me how to test the compressor & it was testing “Good” which was correct. After striping down the wires, replacing all the terminals with new insulated ones? I was able to get the system up & running again. Thanks so much.

Your UTube advice was fantastic! I live in Texas and the temp currently is 99-101 degrees! The company that installed my AC unit two years ago said it would be 7 days before could come for a service call!?? I had to do something! I guessed that it was the capacitor after doing some investigation per your channel. I didn't have a meter, so I was going to go get a new 45/5 uf capacitor hoping that was the problem. I stopped for a soft drink on the way to parts store there was an HVAC truck also getting soft drinks. I asked them if they could check it for me, they looked at the capacitor and saw it was a little rounded on the bottom and top and said "yes, it's bad". I replaced it and the unit began cooling immediately! Thanks again, you saved me and my family some very uncomfortable days! keep up the good work, God bless you and good luck!

[@gloriagaines-hanna256]

You are absolutely fantastic...IT TOOK ME EXACTLY 15 MINUTES TO REPAIR MY AC.....your video is a play by play of every step you need to trouble shoot any problem on your AC...you saved me $350 which would have included a so called diagnostic test to find the electrical problem and parts!!!??!! Your directions on the common wire to AC (blue wire) wall unit was not even connected...and as soon as we hooked that common wire the AC fan came on immediately...WOW!!!! WE HAVE COOL AIR....THANK YOU THANK YOU THANK YOU....by the way. I am a female that did it on my own, with your help...so ladies....do not be afraid....just follow this expert video, and it is a BREEZE!!!!!!

[@WordofAdviceTV]

You're so welcome!! Happy to hear that you were able to fix it and my video helped in the process! I appreciate the nice comment, stay cool! ;)

[@xtraclone]

Agreed! The play by play of how to troubleshoot my non-working furnace/AC unit was very comprehensive. Luckily my issue was only a blown fuse but I would not have even thought to look for a fuse on the control unit. If I had to problem solve an issue again, I would feel confident to go through the steps again. There are details you've explained that can only come from experience on the job. Thank you for your knowledge.

[@WordofAdviceTV]

@@xtraclone Thank you Manny! Glad I could help!

Same here,saved money and was educated at the same time,lol...thanks young man.

@@WordofAdviceTV Great stuff, well done and explained. This video is a keeper.

[@loulambo7596]

I have watched many videos on KZbin that solved my problem, saved me time and saved me money. This video has done ALL THREE and you have my sincere thanks! You can add me to the list of folks who had nothing more than a blocked contactor (solenoid) switch that prevented the compressor unit from getting the message from the thermostat to turn on!! My unit had an ENORMOUS nest of some sort under the plate that COMPLETELY covered and blocked that switch. Cleaned it out and everything is working fine! Problem solved. Time saved. Expensive service call avoided! Thanks again!

[@prsguitars42]

I'm so glad I found this video!!! Tracked my non-working a.c. to a bad capacitor and for only $13.05, I ordered and installed a new one. Great help and education!!!! THANK YOU!!!!!!!

[@lakeimaging7062]

Dude, you are awesome! This video helped me get my AC working with it being over 100 degrees today, and forecast for the next week! You really do a great job of explaining everything. THANK YOU SO MUCH!!!

[@junluo8356]

Clear instructions even a DIY dummy like myself can follow. Diagnosis points to capacitor failure. Bought one and followed your other video to replace. Now my AC is working again a few hours before the heatwave comes in :) What a great service you have provided. You should start a paypal account so I could appreciate your great instructions besides words.

[@johnminicozzi2717]

Thank you for the excellent step by step tutorials. I was able to replace a bad capacitor on my AC unit by following your instructions. The unit works fine and I was able to save hundreds of dollars by doing it myself. I appreciate your willingness to share your knowledge.

[@ricecreekhallow]

Awesome video! The step by step troubleshooting steps made a huge difference. Turns out my issue was a mouse in the compressor housing chewed through both thermostat wires. Saved me a service call on my rental and made the guests staying there happy. Thanks!

[@mauriciozamora5502]

I just want to say thank you so much!!! for all your videos it's like a library for homeowners I appreciate your time to explain very detail everything I was able to fix my my AC, and it's true you should be a teacher the way you explain things is the way people learn, God bless you.

[@panda7am]

I’m an apprentice in the HVAC field, did well in school but still don’t know what I’m doing. Recently started with a company just as a servicing helper. Have had some awesome techs showing me the ropes and making things clear, anyways just wanted to say you’re helping me make some things clear as well. Thank you for sharing the knowledge and I’ll definitely follow up with you and keep watching your videos!! Peace

[@andrewmiller5114]

This is HANDS DOWN the most comprehensive and most DIY friendly KZbin video concerning HVAC systems. This guy is obviously very knowledgeable and has done a great job of explaining how to troubleshoot problems with your HVAC system and how to properly maintain it. Great job 🧐🧰🔧👨‍🔧

[@justinheizer5853]

This video is incredibly helpful. Testing the contactor as you describe and confirming the AC unit turned on was key. I thought it was the capacitor initially, but after pressing the plunger and having the unit come on, I was able to determine the problem was inside the furnace. A wire had come loose in the furnace (it wasn’t obviously loose). Reconnecting that wire did the trick. Thank you so much!

[@danielaustin3705]

I was able to diagnose the problem within minutes. Everyone else needs to take notes. AC capacitor 13 bucks to buy. Thank you thank you. I live in Texas so we need our AC

[@BL4RG4N]

Thanks for the thorough but simple explanations. I'm a homeowner and low-voltage technician, came home to a humid house after a long day of work and just gave an exhausted sigh. You're emulating that second frame of reference needed when something just isn't working right. Turns out my control wire is loose at the unit. I'm familiar with line work but not machinery -- the trick of giving the fan a spin after I got the unit started worked like a charm. I'll have to do a more thorough investigation when I haven't spent all day in the field, but I'm very impressed by this straight-forward video. Thank you for your honest work.

[@BL4RG4N]

Just a follow-up, the problem was the capacitor. It has a nice bubble forming at the top. I figured as much -- the fan was only running when I jump-started the motor by spinning it with a tool (Which indicates possible low-power draw) and there was never any cool air pumping in. This whole ordeal taught me a lot. I'm going around changing my filters and wiping down vents. Thanks for sticking with me!

[@benjiminyoung4353]

Thank you Thank you Thank you! I was all stressed out to call an AC repair person with the fear of getting ripped off, replacing something that did not need to get replaced. I followed the diagnostic steps in your video and also did a major cleaning of everything. I figured I would a least be better educated as to what needed fixing/replacing when I did call a repair person. Best case I was hoping for a dirty relay or a bad capacitor. But a pleasant surprise, after all the cleaning, the relay made a joyful click when I started things up and the AC is running again.

[@WordofAdviceTV]

Happy to hear you were able to get the AC going again! :) Thank you for coming back to leave a comment, stay cool!

[@nastyhvacr]

What is considered getting ripped off? Most contractors are trustworthy. We are paid for our knowledge, experience, credentials, tools, trucks, insurance, business licenses, bonding, vehicle insurance, etc etc. I don’t mind the comments about saving money, I take offense to comments that indicate a certain profession is crooked.

[@chayachan1708]

Excellent walk through explanation of how to troubleshoot the AC unit in a very easy to understand language, one of the greatest videos, thank you!

[@ultramix9659]

[@cnew22]

Awesome and thorough video. I had 0 HVAC knowledge going into this. Thanks to you I was able to diagnose the issue with our AC. Ruling out certain things and confirming others, until our unit was back up and running. My family won't be sweating tonight and you saved us some money. I only got shocked once in the process! 😂 Thanks again!

[@TiffanyM3]

This channel is priceless for new & first-time homeowners! Been using it to troubleshoot my AC which isn't giving me any airflow. Thermostat clicks on, condenser fan & motor starts up, but no AC. (Also noticed icing on copper line outdoors.) Changed filter and AC worked for a day, then quit again. I've flushed condensation drain, even cleaned evap coils, but no luck. May try cleaning condenser coils, but think I've got a blower fan/electrical issue that I'm not comfy tinkering with. Regardless, without these vids I wouldn't have been brave enough to try any DIYs or halfway know what I was talking about lol, so thank you!!

[@dandifonzo]

This video is solid gold. Pointed me right to my capacitor which had exploded. Installed the new one in 15 minutes and was up and running--as good as new. Thanks for such a comprehensive and informative video!

Thanks a million for the clear, concise, and accurate advice. Your presentation strikes the perfect balance between technical and pedagogical. I was ecstatic to learn that my problem could be solved by merely replacing a fuse. Certainly a one-dollar fix is better than hundreds of dollars for a service call by a contractor!

Thank you Carl!! Glad you found the video useful! :)

[@percymchow]

Thank you! Our AC went down during a heat wave one evening this week. I knew it would hours if not days to get it looked at, your video helped me narrow it down to the capacitor. $30 and 12 hours later, cold air is blowing again. Thank you VERY much.

[@pelucas1585]

Wow. I cannot thank you enough. My AC was not working in the middle of summer in the California Desert. You Saved me the home warranty service fee plus any additional fees the AC company would have charged. Thank you x 10000!!!

I'm currently in school, taking heat technically, indoor air quality, and electricity. Your videos are really helping me out. Thanks so much for your knowledge and videos young man.

[@absolutelynothingtoseehere]

Just fixed my AC based on this video: it was the plunger connected to the thermostat wire. Just tapped it a few times with my screwdriver and the unit came on. Afterwards, I blew out all the dust with compressed air, so I hope the plunger stays functioning. I felt fairly confident after watching this video that the plunger was the problem, because my AC compressor made zero noise, as if it weren't even being commanded to turn on.

I am a 62 year old woman, I know nothing about ACs, thanks to your way of instructions, I now have working air conditioner and it cost me less than $20!

[@theredpandar]

This video is awesome. I was able to trace my issue after finding the fuse to be burnt out whenever specific wires were connected. Pulled extra wire and removed the shorted portion! Thank you so much!! I spent $4 only a small pack of fuses, saving me possibly hundreds of dollars against a service call.

[@Azreal357]

This is probably the most comprehensive video I've found about my system. I really appreciate that he is thorough, and doesn't over complicated things. I was considering dropping around $100 just to have a tech come diagnose my system, which after watching this video I am almost certain is the capacitor. So I'll save myself $85+ the cost of repair and just replace it myself.

[@WordofAdviceTV]

Glad you found the video helpful! Good luck with the repairs and stay safe! If you need any help with the capacitor, I have a video on how to check and replace one. (Just look in the description)

[@Azreal357]

Thanks. I actually already used your video to change the capacitor, but that wasn't the problem, it seems to be the compressor, so I'll be calling a tech because that's beyond me to replace and refill coolant.

[@WordofAdviceTV]

Alright! Yeah, if it is a refrigerant issue then you are better off just calling someone. Come back with an update if you don't forget please!

[@lovetrump1088]

WOW....GREAT STUFF! The best summary of TOTAL system troubleshooting for no AC! I LOVE IT!!!!

[@elainejefferson2879]

You are my hero young man!!!! Living in Vegas triple heat where there is no good time for the AC to go on the fritz.,,As Murphy's law prevailed mine went out, after having the vents cleaned and the AC checked. I was totally disappointed. Guess what? I just had to motivate the fan blade to move which was step one of the second video I watched of yours. AWESOME!!!!!

[@Ricky-xi1xn]

I just discovered mine had this same problem. Thank god for this guy. Triple Digits in California. I was wondering do you have to move the blades every time you want it to go or did getting it to budge that once clear out what was there and now it spins up without issue?

[@haeremaru]

Excellent video. I only tinker with the AC when there is a problem (every few years). Great refresher on the few things I already knew, and a lot of information that I didn't know. Very clear, nice pace.
