Daniel W Middletown , DE July 16, 2019 Appliance: Model PTC STARTER (MCBR100) My refrigerator was not cooling properly and there was a clicking sound My refrigerator was not cooling properly and there was a clicking sound. Seeing there were similar problems with this and the part needing replacement was the PTC starter, I ordered one from Appliance Parts Pros and after less than a 15-minute repair, it's working as good as new.
