I was called to replace a broken defrost bimetal in a refrigerator. The bimetal is a metal strip that controls the defrost cycle. It was broken and needed to be replaced. I removed the old bimetal and installed a new one. I also checked the defrost timer and thermostat to ensure they were working properly. After completing the repairs, I tested the refrigerator to ensure it was working correctly. The customer was happy with the work and paid me for the service.
