Description
Defrost timer that advances the refrigerator's defrost cycle at roughly six-hour intervals to help prevent excessive frost buildup and keep cooling consistent. Replaces a failed timer to restore regular defrost scheduling. What it does:
- Advances the defrost cycle so the heater can melt frost from the evaporator on a timed schedule.
- Helps prevent heavy ice buildup that can reduce airflow and cooling performance.
- Common symptoms of a failing timer: excessive frost or ice accumulation, compressor running constantly, or inconsistent temperatures.
- Works with mechanical defrost systems to alternate between cooling and defrost intervals.
What's included: One defrost timer. Install notes:
- Disconnect power to the appliance before servicing to avoid electrical shock.
- Handle connectors and wiring carefully; ensure all terminals are fully seated.
- Mounting hardware and connector types can vary by model—retain original fasteners and note wiring positions before removal.
