Thank for this great explanation. One question, is it normal that when forcing defrost on PCB, pressing microswitch two times on PCB like in the video, defrost start but is switch off again after a few tens of seconds?

[@techsupport7898]

Yes, at Test Mode defrost will continue also until D sensor reach +10 degree. If temperature already have above 10 then PCB will provide supply to Heater only for ten seconds.

@@techsupport7898 In fact, I checked test mode defrost again while evaporator was full of ice. Same thing, supply to heater was off after tens seconds even defrost sensor was ice cold.

[@techsupport7898]

@@yannmoreau4605 that means issue with the Defrost sensor, giving wrong feedback to PCB, accordingly PCB power off the supply to Heater. In this case Sensor value changed. Not open or short.
