The SC954 – Supco Refrigerator Defrost Timer, 10h 30min is a universal OEM-spec replacement defrost timer designed for refrigerators and freezers. It is a widely used GE-compatible defrost control component that manages automatic defrost cycles to prevent frost buildup and maintain stable cooling performance. Available through Appliance Kingdom, this part ships across Canada with fast delivery for homeowners, landlords, and appliance repair professionals.

This timer operates on a 10-hour cooling cycle with a 30-minute defrost cycle, ensuring consistent temperature regulation and efficient defrosting in domestic refrigeration systems.

Function & Importance of the Defrost Timer

The defrost timer is the control device that switches the refrigerator between cooling mode and defrost mode. In normal operation:

• It runs the compressor and cooling system for approximately 10 hours
• Then switches to defrost mode for about 30 minutes
• This cycle repeats continuously

This prevents ice buildup on the evaporator coil, which is essential for maintaining airflow and cooling efficiency.

Using a correct OEM-spec timer like the SC954 is important because:

• Incorrect timing can lead to excessive frost buildup or warming issues
• It ensures compressor protection and proper defrost heater activation
• It maintains energy efficiency and extends appliance lifespan

Common Symptoms of a Faulty Defrost Timer

A failing defrost timer in a refrigerator may cause:

• Excess frost buildup inside freezer compartment
• Refrigerator not cooling properly
• Freezer too warm or inconsistent temperature
• Compressor running continuously or not starting
• Defrost cycle not activating
• Water leakage from ice melt overflow
• Refrigerator “stuck” in cooling or defrost mode

If your appliance shows these issues, replacing the defrost timer is often a strong first diagnostic step.
