Hello my friends!I visited an a/c inverter and the problem was that during the start of heat operation the machine did not start and simply flashed the "timer led" 2 times!
Since I had the service manual I checked that the "reverse communication at the beginning" was the problem.
But I also checked that during its try to start I did not have any voltage on the compressor.
I had communication through the interior circuit but the outdoor pcb did not send voltage via inverter to the compressor.
After this procedure that lasted about 20 seconds the a/c flashed the error and stopped operating.
Do you have any idea of the problem?
Thanks!!
