How to test Daikin PCB for Communication Faults.

[@brewaz]

You are an inspiration, so many people will not share this type of information!

@@brewaz thank you, I hope it helps!

Hey Mitch, enjoying your video. Clearly explained and easy to understand with real world tests. Keep them up, well done.

@@MitchellMIller-db7gk thanks 🙏🏻

[@robalexander7348]

Explained well Mitch, so handy for the boys entering into the A/C game 👍

[@HHK1090]

Really liked this video! Very informative. Thank you Mitch!

[@maracservices]

My pleasure!

[@せとやん-d9l]

It's a very easy-to-understand explanation. There are so many types of multimeters. If there is a particularly recommended multimeter, I would like to see that video someday.

Cant go wrong with a Fluke - Costly but well worth it, you could be risking your life using a cheap tester

[@maracservices]

I recommend the fluke kit that’s designed for hvac. It comes with the multimeter you see in this video and another one that can measure amps. Cheers mate

Really informative video! Thank you and keep up the good work!

Thanks mate

Thanks Mitch, Do you know how to confirm if its the ourdoor PCB problen or indoor PCB problem?

Hey Mitch, new subscriber here.⭐️🌟⭐️

[@michaelburns5680]

Not sure if you have one but the most valuable piece of hardware you can have for checking Daikin residential equipment is the Daikin Transmission Checker (I don’t even know if they sell it anymore). It hooks up to 1,2,3 terminals and it tells you all the indoor data such as sensors and requested capacity sent to the outdoor. On the outdoor side it tells you sensors, outdoor fan data, compressor hz etc. If it doesn’t pick up the indoor or outdoor on the transmission checker it generally sends you in the right direction to go checking.

[@maracservices]

Interesting, I can’t say I’ve seen one of those. Sounds pretty handy!

[@Optuss]

Thanks Mitch. What would you expect to see for the low/high readings with bad boards?

[@mattgansky2179]

If the DC volts are not in the range, does that mean bad board or is there a fix ?

[@maracservices]

@@mattgansky2179 that means bad board mate

[@45KevinG45]

Hey, so if the dc voltage is above or below the 10-50vdc. What does that indicate?

[@aus_aircon_ref_mech6671]

Hello Mitch Excellent video! I never knew the min-max function on my multimeter! Great information here. Does this mean that if you get zero for the high voltage then the outdoor board is bad? If you get zero for the lower voltage then the indoor PCB is bad? Or would you just change both?

[@eliaskoch5604]

if there is 45 dc and 0dc then is it the indoor bord faulty and if it 10dc then 0dc is it the outdoor bord faulty ????

[@boulmo9167]

It depend If that happen then you probably have to check indoor and outdoor board check the fuses it could be both board that’s bad but usually outdoor bad board are the common one

[@ThomasMarchant-c1y]

Normally if the indoor fan runs on fan only mode. Usually the outdoor board is the bad one

[@KINGDADDYBOB]

If you hold orange meter button while rotating center knob to on, the meter will not time off/out.
