I am looking for some help to diagnose a freezer fault. This freezer is only 22 month old, and it is kept in a detatched garage. It recently got quite frosted up, but after defrosting it would not run. It would start the fan and compressor, but they stop after about 5 secs. I tried a new controller board, but it made no difference. I can measure the resistance of the NTC sensor, so I assume that is also working. Other than the complete evaporator unit I can’t see what else it could be.
Any suggestions.
Thanks
