Freezer not cooling at all; interior is warm and food is thawing, but lights may still work.

Safety: Unplug the freezer before accessing the compressor or controls. Do not attempt to open the sealed system.

Steps:

• Listen for operation: With the unit plugged in, listen for compressor hum or clicking. Repeated clicking every few minutes often indicates a start device problem.
• Check temperature control: Ensure the thermostat or control is not set to OFF. Turn to the coldest setting and wait several minutes.
• Access compressor compartment: Remove the rear lower cover. Inspect the start relay/overload on the compressor for burn marks or melted plastic.
• Test start device: With power disconnected, remove the start relay/overload and test for continuity. Replace with an OEM Westinghouse start device if open or rattling.
• Test compressor windings: Measure resistance between compressor pins and to ground. If windings are open or shorted to ground, the compressor is faulty and requires professional replacement.
• Check control output: If the compressor and start device are good, the thermostat or main control board may not be sending power. Test for voltage at the compressor terminals (by a qualified person) and replace the control if no output.
