I had an HVAC guy.....actually, lets just call him a guy off the street. Guy came to a rental and told my tenant that she needed a whole new HVAC system...told her to tell me that it could come out of the rent. She was fairly young and I explained that she needs to watch out for people like this in life......Oh and a $50 dollar thermostat fixed the system. Still working about ten years later.

Good video. Please add that the wire itself could be bad. You mentioned the wiring could be wrong, as in wrong colors to wrong terminals, but a bad 24vac line would cause the same issues. Doing this same test at the back of the thermostat would eliminate the wire being bad, and the thermostat.

He's being proactive and managing his workload upstream. 🤣 I doubt it's really has much of an impact. There's people that are too scared to even take off the panel and then there's the bound and determined DIY types that are gonna get in there upgrade their minor issue to properly f_cked status and will have to call anyway.

[@adamrspears1981]

So how do you check at the pc board if there is a call for heat? Set your meter to volts AC. Put 1 meter lead on the W1 terminal. Put other meter lead on the R terminal. If your meter reads 24 to 27 or so volts, the thermostat does not have a call for heat. If your meter reads 0 volts, then the thermostat has a call for heat. Is this correct? If not, please correct my error(s). Thanks in advance.

[@WordofAdviceTV]

What you said is correct. Although when I check voltages at the control board, I prefer to just check W to C. When there is a call for heat, there will be around 27 volts. No call for heat, 0v.

Is there any advantage to bypass the Thermostat at Thermostat or at control panel in the attic? Great video. Thanks.

[@darianbethune5257]

It could help you to determine bad wiring by doing it at the thermostat. If it doesn't work there but does at the air handler then it could be bad wiring. It could also be a stuck float in a condensation pump so don't forget to check that as well.

[@youraveragedad5594]

[@MT-rg4dm]

Great video quick question what if your furnace doesn’t turn off it doesn’t seem to be sensing room temperature and just keeps running all day is that a thermostat problem?

[@WordofAdviceTV]

The easiest way to check that is to just pull the thermostat off the wall. If your furnace runs even with the thermostat off it's base, then it's a bad control board. If it turns off, then the thermostat is bad. But when you say the furnace continues to run, is it just the blower motor running or are the burners on as well? Maybe your thermostat fan setting is just set to ON instead of AUTO

hi my system is completly empty i will add 410a to suction line a little at a time what i want to know is unit running while im adding freon thank you jim

[@WordofAdviceTV]

Do you have a scale? I would weigh in the factory charge with the unit turned off first. That way you can open up the low and high side on the gauges and let it fill up, wait for a while to let it equalize, and turn it on and add a bit more if needed. If the unit is completely empty, it will likely leak back out pretty quick though. That being said, let me answer your actual question now :) Yeah, you would add it through the suction side and the tank would be upside down since 410a has to be charged in liquid only if you are charging while the unit is running. And yes, a little at a time. The rule of thumb is that you cannot go over 10-15psi from the starting point otherwise you could slug the compressor. Hope that helps!

[@jamesrooney7689]

thank you for your time and advice i really appreciate it i have a scale and will do as you say again thank you jim

[@jamesrooney7689]

hi if i add 410a with system off i do not have to turn tank upside down is that correct using scale

[@WordofAdviceTV]

I would still flip the tank upside down. R410a is a blended refrigerant which means it is a mix of a few refrigerants. So it should always go in as a liquid. If it goes in as a vapor, then the refrigerant mixture can be unbalanced which could cause problems.

[@WordofAdviceTV]

Thanks Joey! Sorry to hear about your problem. Do you have a multi meter with leads that you can check voltage with? That would help quite a bit. 1. Did you have that error code before you replaced the ignitor? 2. Are you sure you replaced the ignitor with the right replacement? They can vary in the amount voltage they are designed for. 3. Have you double checked and made sure the ignitor and flame sensor are not touching anything? Like the burners. 3. Does your furnace do anything at all when you turn on the heat? Does the inducer motor come on and can you hear the gas valve open for a few seconds? 4. If you have a meter, check if your ignitor is getting voltage by sticking both leads in on the back side of the plug. If your ignitor is getting 120v (usually it's 120v) but it is not glowing, then your ignitor is bad. 5. If you are not getting 120v going to the ignitor, then I would suspect the control board. Hope that helps man! Good luck!

[@joeyjavier9010]

@@WordofAdviceTV I checked the voltage of the ignitor and I'm getting only 105 volts then when the gas valve opened the voltage drops down to 25 volts.

[@WordofAdviceTV]

Even with 105 volts, the igniter would start to glow. Have you tried checking the resistance/ohms of the new ignitor? It sounds like the new one could be bad. The voltage drop after the gas valve opens is normal operation though. The ignitor turns off after the burners light. If you have a long shaft lighter, you can stick it under the burner face where the ignitor is and when the gas valve opens, it will light the burners "manually". If you need to just heat up the house you can do that temporarily. (do it carefully of course)

use a multi meter check between R and C.

Like latent fusion said, the best way would be to check it with a meter. If you have 24v between R and C, that means your thermostat is getting power. Just a heads up, some programmable thermostats require a common wire. If you look at your thermostat wires that go into the furnace, how many wires come out of the big wire? Are all of them connected? Could you tell me where each wire goes?

[@ednovak6060]

Thanks for the excellent video! If you have a minute for a question... the jumper at the control panel successfully turns on the heater, but it takes about an hour after I connect the jumper. If I disconnect the jumper, the heat turns off immediately,. However the fan is on and won't turn off (as long as the general power supply switch is turned on). The temperature setting on the thermostat seems to have no impact on the function, and won't turn anything on or off. Is it likely a bad thermostat, or maybe control panel?

[@gregorysans]

I read that you should use a resistor when you bypass a thermostat. Is there any truth in that? My boiler is short cycling with a nest thermostat and I want to bypass it to see it’s the thermostat or the boiler control Board.

[@Budl1te]

Nice video. I have 24v between red and yellow/common/fan(black) at the thermostat, when I jump them though, nothing happens? touch red and Black together and the fan should come on but it doesn't? Been trying to install an amazon thermostat on my heat pump with heat strip(no gas) When I set it up I can get the heat to come on but when I set AC and lower the temp the outside unit comes on for about 5-20 seconds, sounds like it is on low speed for the compressor fan, then it just turns off. it worked fine prior to this with the old non programmable thermostat. took a picture of the wires before removing them from the old just in case it was wired different but all looks good as far as that goes. In my mind, If I am getting voltage on the wires, then, when jumped, the fan should turn on. I replaced all three capacitors on the condenser unit outside, replaced the capacitor on the furnace and replaced the control board. it is an older (2004) Ruud furnace and compressor. Any ideas?

If I put a jumper wire from R to W, on the furnace board, would the furnace run nonstop (assuming furnace is ok)? Will furnace overheat? Also, if I have a battery operated digital 24 volt/Millivolt thermostat in my hand (not wired into a furnace) can I test the R/W wires with meter? If so, how? (If I set tstat to Heat, and set desired temp to 75 degrees, when tstat says it is 73 - to call for heat, and fan on Auto - do I test for continuity from R to W,? Or do I set meter to look for Volts? And, if volts, would I test for AC, DC, or DC millivolts on the meter?) Also, can I take the questionable tstat that is in my hand (not on the wall) to test it on the furnace board (sort of like a jumper wire), and set tstat to call for heat, and use wires from R on tstat, to R on furnace board, and wire from W on tsat to W on furnace board - to test to see if the tstat is working?

[@WVHarvester]

When you bypass from R to Y to turn on your ac should the outside unit fan come on as well ?

[@jonkc3635]

Only your outside fan should be running and not your furnace fan. When the thermostat calls for cooling. It will actually energize the wires R,G,Y.

2:30 what you came here for.

If you have a bad thermostat, and it's late at night and the stores are all closed - can you left the jumper wire from Rh to W, overnight - because the high limit will get tripped whenever the furnace temp goes above the limit switches temp setting, and the limit will control the furnace cycling off and on through the night.

If thats the case, watch my pressure switch videos for more on that. Now if all the switches seem to be okay and there's no LED error code blinking when thermostat is set to heat..

I’ve been watching all of your videos trying to figure out my HVAC problem. I tried using a jumper from R to W to get my heat to run and it won’t turn on. Actually, the jumper didn’t turn on anything. Not the fan, not the AC and not the heat. When I used the meter I have 24 volts when I connect R-G, R-Y but nothing for R-W. Is my control board bad?

[@MrDsqrd222]

You have 0 volts at RW because the tstat is working and there’s a call for heat. Your problem is elsewhere.

[@timbrown9305]

Your first comment about testing fan at furnace means you thermostat is bad... could also be your wiring and not the stat. I get calls on many rentals where the owner ran a wire in a very bad way. Furnace quits but isn't the thermostat. Is your hot water relief valve piped to within 6 inches of floor?

[@WordofAdviceTV]

It's about 8 inches from the floor

[@meTimetraveler]

it's not the voltage that kills, it's the Amps. Takes as little as 1/2 of an Amp across your heart to kill you. like if you have one hand on the grounded sheet metal and you touch a live wire with the other hand. Consider this, a static shock like taking a sweater off is probably around 2,000 volts, fortunately only in the pico Amp range. so half a volt at 1 amp could be potentially lethal. Good video

I tested everything for 3 days but skipped bypassing thermostat. Thanks gb

[@daleatkin8927]

I’m thinking of wiring a smart relay in parallel with my thermostat to turn on and off my blower when a temperature difference between two areas is detected. Can someone tell me why I shouldn’t do this? (Anything I’m not thinking of?)

[@PattiMyers-tq7tp]

My nest is saying continue setup in the Google app what do I do

[@DailyOpinionsUSA]

pretty cool

[@darrins3206]

Why would the fan come on if you only jumped the red (power) wire and the yellow (compressor) wire and you didn't also jump the red (power) wire to the green (fan) wire?? It would seem to me that in your example, your outside AC compressor would come on, but your inside fan motor would not come on because it was not jumped.

[@mauivang7283]

Can you bypass if the board is bad?

[@WordofAdviceTV]

Well it depends on what your board is doing. Sometimes bypassing it will not work. Do you know where you are losing your voltage?

[@mauivang7283]

Word of Advice TV I bypass and it works for furnace

[@WordofAdviceTV]

So you are putting the jumper between R and W?

[@meTimetraveler]

you also need to close the interlock switch

[@davidmckinney6577]

Hey buddy how are you doing??

[@jerrymeshew1970]

What if there is no control board

[@5238117]

Then you have a AH or furnace that is old.

[@aj_besas]

what if the thermostat is working but the compressor runs only when starting the ac and stop after few minutes.

[@adamsaquatics3332]

This is old, but I can turn the fan on from the thermostat but it won't kick it on to let gas in and light up

[@markstuck334]

My furnace will run on fan on only not auto. I try to jump the red and green wires at the control board and all it does is click. No fan. Have you ever seen this before. It's a york gas pack

[@billlavoie7272]

I’m in the dark here 🤷‍♂️

[@cygnetsxsirens]

So your saying that in an emergency situation and your thermostat is not working properly and you don't have any way to get another one you can just twist three wires together to turn it on

[@lukemeissner1741]

Just used this to not freeze to death in my apartment because my landlord is awful.

[@quickieswithscottechristie]

Jumper!! lol
