What to do if Mitsubishi PUHZ-P200YHA display disappears after remote is operated?
If the remote controller's display disappears soon after operation, it might be because the system requires about 30 seconds after canceling a function selection before you can operate it again. Please wait for about 30 seconds and then try again.
Why no display on my Mitsubishi Air Conditioner remote controller?
If no display appears when you turn on the Mitsubishi Air Conditioner remote controller, there could be several reasons. First, the wiring between the indoor and outdoor unit might be incorrect; specifically, the polarity for S1, S2, and S3 could be wrong, so check and correct it. Second, the remote controller transmission wire could be shorted, so inspect and replace it if needed. Third, there might not be an outdoor unit with address 0, so verify the outdoor unit address and set it to 0. Finally, the remote controller transmission wire could be open, so check it for continuity.
How to fix Mitsubishi PUHZ-P200YHA showing 'P' and 't' after power on?
If your Mitsubishi Air Conditioner displays 'P' for 3 minutes followed by 't', it indicates a problem with the outdoor terminal block connection (L1, L2, L3 and S1, S2, S3). Check the connection of the outdoor terminal block. Also, it could mean the outdoor unit’s protection device connector is open. Make sure that the protection device connector is securely connected.
