The relay on the small circuit board chatters and sometimes

Resolved Question:

The relay on the small circuit board chatters and sometimes the solenoid doesn't open the flapper which controls the cold air coming into the refrigeration compartment so the compartment stays warm and the freezer ices up and the compressor operates all the time . then I have to manually defrost the freezer. can I replace the relay only or do I have to replace thewhole PCB? The refrigerator is a ModelMSD2756GEB, the serial number is XXXXX

Thank you for using Just Answer.


The fix is to replace the whole PCB. The service repair manuals generally do not advise replacing any components on the boards.


The control for the defrost is failing and the relay may or may not be the actual cause of the problem.
