Panasonic Cassette
Hi guiys i have a problem with a panasonic cassette Indoor - CS-F50DB4E5
Outdoor - CU-B50DBE8
Now what happens is after 10 mins of running the unit shuts down the compressor and outdoor fans as if it was cycling off. Problem was return air was at 19 degrees and i had it set at 16. So i held the air on sensor to heat it up and nothing unit would not cut back in. So i turned the unit off and back on at the remote and unit kicked in.
I spoke to service center and they said may be a thermistor problem. I have previously installed new PC Boards to indoor and outdoor unit have i done something wrong? There is no wall controller only remote so i can only go by fault code LED on the outdoor unit.
Here are my temp readings.
Indoor on High Fan speed - Air ON - 19 degrees
Air Off - 5-7 degrees
Suction pressure was about 750kpa on R410a
Condensor Outdoor fans appeared to be on high fan.
Air On - 30.5 degrees
Air off - 23.5 degrees
Compressor Amp draw was 8.2 amps on all 3 phases.
Thanks
