Very good video on troubleshooting. Very helpful.
Thanks for this video, I haven't worked with this kind of A/C but it's good to learn something new and so important . From Venezuela. 🇻🇪👏🙋♂️
Great video and thank you very much, I typically work on the water source heat pump’s and I do have experience installing Dr. splits but I’ve never had to service one,,, this video has given me a great first step in troubleshooting☝️🙏🏾🙏🏾🙏🏾🍺
Great video, very informative.
Thank you, very helpful.
Very thorough
Good video. Very helpful
Thanks for the video =)
thank you for this video it made me call a repair tech within 4 minutes of watching because i realized i have no chance of doing this with my cute little pink tool set from home depot lol
wires crossed where? Are you going to do a video where you fix the issue?
HI How to check for inverter compressor voltage?
What is the minimum voltage for the compressor to opreate
Fujitsu use a diode on black lead to show a steady voltage on 3 or signal wire
Is that reading method the same for all inverter mini splits?
If you lose one leg coming into the unit would that cause damage to the unit or do they protect themself?
Thank you, again. I have watched it the second time.
Zone 1, OU (outdoor unit) has identified a problem with the indoor PCB. The OU is giving a steady voltage between S2 and S3 and should fluctuate on DCV. This means that the indoor PCB needs replaced.
On Zone 2, S2 to S3 is fluctuating in AC at low voltage. We should have a steady 210V. DC should be fluctuating between 12 and 26V at S2 to S3 but it is fluctuating at AC high voltage instead. That is an indicative that a short or a cross in the wiring. Is the PCB of OU faulty, as well?
is this training from trane mitsubishi hvac classes on their website?
Hello
I would like some one tell me where I can get mini slips troubleshooting please
Thank you. Where can I find EP2, the continuation of this?
You're welcome! Technically Speaking is our series of videos on different topics. There isn't a second episode for this topic, however we plan to release more videos on Mitsubishi Troubleshooting soon.
Hello Sir,
Is it possible to add reverse valve in the inverter ac's. The ac is of R32 gas and 2.2 ton.. Mitsubishi electric GR series model
Posssible yes. Not even close to worth it. You mine as well but a new system
Why not remove signal wire at outdoor unit and measure out there
Where is the video that tells you what it means if both indoor and outdoor units have non fluctuating DC current between s2 s3
I been researching, the s3 connection has 120v ac but conducts DC voltage like power line communicating. There is two capacitors at the S3 connector where the DC signals is send from one end and stop at the other end and is collected for capacitor read the pulsation signals and passes the AC signal flowing with no interference
To connect without board
Does anyone know if this is fairly standard across brands? (Mitsubishi, Daikin, Fujitsu, etc?) In my limited experience with them (almost exclusively installation), they appear to be wired in much the same way but I have no idea in the differences of board function
This is pretty standard , although some makes like toshiba have fluctuating ac voltage between s2 & s3 and so s1 to s3 will also be fluctuating ac voltage
What if I have power coming to the outdoor circuit board but none leaving to the indoor units?
More than likely it'll be a fuse has blown
Anyone else notice the suction line freezing?
Probably from the board not communicating with the inside, so the blower wheel is not operating. Maybe reason for a freezing up line.
Wapp nu plzzz sir
