If your Kenmore Model 363's ice maker stopped working after an electrical outage, despite replacing the water valve and ice maker, there are several potential causes to consider. Since the freezer and refrigerator are functioning correctly, the issue seems isolated to the ice-making mechanism.
First, ensure that the water supply to the ice maker is functioning correctly. Sometimes, the line can become frozen or clogged, especially after a power outage, so check for any kinks or blockages in the line. Also, verify that the electrical connection to the ice maker is secure. The wiring harness connecting the ice maker to the power supply needs to be properly attached and not damaged.
The ice maker's control module or thermostat might have been affected by the power outage. These components are responsible for triggering the ice-making cycle, and if they're malfunctioning, the ice maker won't start its cycle. Some models require a manual reset after a power outage or when a new ice maker is installed, so check your user manual for instructions on resetting the ice maker.
Additionally, the fill tube that supplies water to the ice maker can sometimes freeze, preventing water from reaching the ice maker. Ensure it's not blocked with ice. If these steps don't resolve the issue, it might be time to consult with a professional appliance technician for a more detailed diagnosis.
Given the age of your refrigerator, it's also worth considering that some components might have worn out over time. However, this doesn't necessarily explain the sudden stop in ice production following a power outage.
