Cleaning every 6-8 weeks! Just rub it down with some dielectric grease!

I have a Goodman 2 stage AC unit (5ton) and Goodman matching air handler - both communicating. Both inside and outside boards were replaced. 3 service calls but can't seem to stop the unit from working while the tech is here, and then switching to "lost communication with the air conditioner" or "outdoor sensor needs to be added" or waiting for equipment. Short power cycles don't fix it but if I leave it off for an hour or more it sometimes comes right on and cools. Had three false repairs. Worked all night only to fail again in the morning. Not sure the techs can figure this out, especially with new boards already. Not likely wiring, or a long rest wouldn't fix it. could it be abad thermostat? Pulling my hair out here! BTW, awesome video. Your detailed explanation is perfection.

Good video 👍

Really a helpful video. Have a very similar problem but the thermostat has been searching for the system for hours and can't find it. Yet it never comes up with the "Not Found" message as it says it would by the "Help" button. FYI, this is a CTK03. Do your have any insight as to what might be the issue? In a relatively rural area and have already spent money on services whose techs were absolutely clueless. No error messages on the boards of either the air handler or condenser. Supply voltage is ~28V AC and voltage differential between data lines is ~650mv AC. Would seem that is within system specs. Have found some ideas and looking for more insight. Firm believer in not being able to fix a problem if you do not know what it is. Thanks for any help you can provide.

That’s so insane how expensive that little daiken magnet, it’s so ridiculous

Bring it Scott You are the Man. We need this Bossman

Keep it up.

Tank u bro

I (tech) have a question about the network. Do you know if it has dual band functionality? The thermostat's only able to find the 2G network and won't show the 5G which I can connect to throughout the home.

For the Daikin fit heat pump, is there a way to adjust the fan speed? I just recently had a Daikin fit HP system, the noise level is crazy, and the fan seems running 100% full blast all the time, not really as what they claimed as a variable speed system..very sad..... is there any advice? really appreciated!!

I have a Daikin Fit one. I think i had condensation when I used the heater. There no condensation from the outside inverter when using AC? Now the thermostat is a blank white ghost screen with power. AC still working, but nothing showing on my thermostat. When it gets fixed, I'll look into this. Good stuff!

Great video! How can I find out what the installer password is? Mine is set to 69 min for AC and I would like to change to 68 as my wife would like it just a bit cooler at night

Excellent excellent excellent. Thank you 🎉

Yesssss clear and precise the video, thank you

Thank you bro

I have a Daikin Ducted mini. The thermostat shows the temperature at the air handler. Is there a way to make it read at the wall thermostat?

Good job man

Nice tricks... thank you. Question... hiw you figure that shit out? Curious in so cal

I feel like this is a known issues with this brand but installers are pushing them. We just had one installed, felt great the first few days but then started to show a lower temp than actual (probably a 4-5 degree difference). That’s huge!! Followed your steps and saw it came calibrated to add 3 degrees already!! Either came from the manufacturer like that or the installers did that. Shady!!

how do u remove drain tray

Goodman won't sell their Side Discharge units unless the installer has training on how to program it. Problematic for DIY :|

Thanks you very much, you answer every single question to the T, now my wife can enjoy some cooler ac.

Hello, thank you for detailed explanation. I noticed that yout air handler had a 2 hours drift from the heat pump, does it mean the air handler stays ON all the time? I got a new system and my air handler stays ON regardless the whole system is off, i usually see the outside unit fan running slow for a few minutes (2-5) throughout the day, is that normal? I built a monitoring system via Daikin One API but im unable to spot why is it running. Appreciate your insight!

It’s a piece of crap I have two of these crap things!!!!! My main stat just runs constantly even on auto mode it never drops!!!!! Then sometimes it’s nice and cool and then other times it’s humid and mucky in the house. I had it set at 72 and it was just so uncomfortable and humid so I dropped it to 68 and it’s nice and cool but it’s just running continuously doesn’t cycle with auto on. When u bring the temp up to make it shut off it jolts the temp right up and back on it goes!!!! Any thoughts on what might be going on? I’ve drove my self insane trying to figure out why this expensive wall mount won’t do its job when it’s in auto mode. If anyone has any tips I would be forever grateful lol 😂

Thanks amigo

Great video.

I forgot to add. The AC unit will turn off if I pull the thermostat. I have the Daikin One thermostat.

I have a question. I had my system put in. It is gas furnace and I have a 2 ton AC. The problem is since the dealer installed the unit the AC runs 24/7 unless I pull the outside fuses. Which I did during the winter. I have to leave the thermostat on heat during the summer months or the AC will freeze me out. If I set it to cool, It never shuts off. Is there anything I can look for? I had this system put in 2 years ago and the dealer hasn't been able to figure it out. They tried replacing the thermostat, But it still does it. I have no problems trouble shooting my system as I have worked with trouble shooting PLC's and other equipment and repairing for my work. I'm at my wits end. I don't want to have to buy another brand unit. I have the books for installing the units but have no clue what to look for on this one. Thanks.

Hello, I have a Daiken 4 Ton DX17vss481ba outside and a DV48fecd14 inside (installed 9/2023. The evap coil started dripping water to the floor under the unit. I have had techs out, the coil is clean, the charge is correct but i have high static pressure due to old metal duct work in my home. Never an issue with conventual AC's in the past however with the constant ramping up and down of the inverter technology this has begun. Temp at the top of the air handler (measured at the base of the ductwork exiting the cabinet is 56 degrees). All ducts in the home are open...curious how you would program the thermostat to prevent the drip that occurs I believe at lower fan speeds. I would prefer not to have to replace all of the ductwork in this 1955 home :). Unfortunately not many techs are experts w these systems. Thank you!

It actually works, I bought one to unstick an EEV in an over engineered POS Trane Tam7

I see other people talk a lot and show a bit, but you unique ❤ and people understand well Good teacher

How do you remove the blower roller on a gold air 12000btu indoor unit. Becos the drain tray has no clips to remove it and no screw on the blower itself to loosen and take off?

Thank you for this thorough explanation. I'm based in South Florida and just had a new 5 ton Fit system installed a few days ago. I realized that the temp readout on the One Touch was off as we were not comfortable and used 2 source temp/humidity gages I purchased online to verify. The system wasn't cooling as low as we desired and the tech showed how he was compensating for this delta using his gage. Unfortunately, there was a lag in his reading and not certain if the offsets were exactly correct. I reset the calibration based on an average of 8-10 readings on both gages ( +1 F and and -3%RH) and the One Touch over a 24 hr period. On average, the Daikin read 75 deg F and 53.6% RH. The 2 independent gages read 76.1 and 77 deg F, and RH of 48.3% and 49.9%. My question is: I did not waiting 30 mins as you stated in your video before adjusting the offsets. Would that cause any issues?

Do you have any more resources online that you could link me too? Maybe a little bit more in depth on this tool? We've got a bunch of these at our shop and our regional service representative in our area It's been somewhat of a letdown so far. This little video nugget here was very helpful.

If one out of 4 indoor units in an LG multi-head system is not heating, what could its EEV be doing? Stuck open or closed or partially open or partially closed?

Hello I have a Comfortnet Thermostat that is connected to the Honeywell HE360 Humidifier, the humidifier is not turning on so I bought a new fan side replacement to test and see if it was a broken fan control board or fan, I also replaced the solenoid (as the unit was very old). I am still not getting this unit to turn on so I am thinking it maybe the connection to the Thermostat (I know its connected to the IFC on the board) whats the best way to confirm the signal from the Thermostat is connecting with the humidifier?

What additional steps are needed to commission this with dual fuel with the heat pump set as primary heat source?

Good video thanks

Is there a way to program soft start for AC and Heat with this thermostat?

I owned a daikin dealership never have I talked to anyone with such knowledge. Simply the best

Great video 💯👍👍👍

Very interesting and informative 💯👍👍👍

Thanks. Helped me.

This is for rookies.A decent magnet does the job.Poor guy.

No set screw

How did you wire the Aux heat to the thermostat? The instructions talk about 24V AC signal must be routed through one of the aux contacts of the thermostat and the use of a SPST relay. I'm confused.

the video was excellent, I have a outdoor sensor needs to be added message that needs to be corrected. The system has one but it wasn't added??? I went through the whole thing twice but I still have the message. thanks, Gil

Thanks for the Video,what is the ID of the Daikin magnet? My TEEV has a larger OD .

Thank you sooooo much, was struggling all day and finally removed the blower wheel thanks to this video ❤️❤️

Hi Scott: Great stuff you taught. I have been using the thermostat CTK01 for my AC/Heat Amana system for about ten years, but now it has a touchscreen problem that I need to replace. Can I purchase the CTK04AE for a direct one-to-one replacement? It's due to the fact that the wires ( C, R, 1 and 2) layout look the same on both unit CTK01 and CTK04AE . That makes it very simple for me to follow to install it myself. Once installed, for setting the CTK04AE up, I would just follow what you showed on the video. Do I need to provide "Dealer Information" as it showed in the Installation Guide for the ComfortNet CTK04AE? Much thanks for any input you would provide.
