Hello, i have a 10 yr old ge profile french door refrigerator PFRS5NBWA with the inverter compressor. recently the freezer temperature has been rising from 0 to sometimes 50 degrees before compressor kicks in, then fridge and freezer cool of to 37/0 as designed, holds for a while then starts to heat up again. I have done many diagnostics tests, measured input voltages to the inverter, resistance at the compressor, checked frost pattern on evaporator coil, checked defrost heater, damper operation, thermistor resistances at board connector J1 and i am now stumped. Suspecting inverter board but dont want to buy one and find out that isnt the issue. Should note that the 100% runtime test did not work. Any help would be appreciated, thank you
