How to Fix / Troubleshooting
Safety First: Unplug the freezer before touching any moving parts or metal tubing.
- Step 1 – Isolate noise source: Listen at the front, back, and inside to determine if the noise comes from the compressor area, condenser fan, or evaporator fan.
- Step 2 – Check leveling: Ensure the Gladiator freezer is level and all four feet are firmly on the floor. Adjust leveling legs as needed.
- Step 3 – Inspect fans: Remove the rear access panel and interior rear panel to inspect condenser and evaporator fan motors. Remove any debris and ensure blades are not rubbing. Replace noisy or wobbling fan motors.
- Step 4 – Address relay clicking: Repeated clicking near the compressor often indicates a bad start relay. Replace it as described in other entries.
