Troubleshooting your Wards upright freezer when interior lights don't work
If your interior lights don't turn on when you open the freezer door and you already replaced the light bulb, then the door switch may have failed. Unplug the freezer and test the door switch with a multimeter. Replace the door switch if it failed.
Some upright freezers use LED's to light the interior compartment. If an LED light board doesn't light up when activated, replace the light board.
Faulty lighting system wiring also prevents interior lights from working. Replace or repair any damaged wiring in the lighting system.
Troubleshooting your Wards upright freezer when it won't run
If the freezer has electrical power-the inside light turns on-but the compressor won't run, a failed cold control thermostat could be the problem. If your freezer has electronic controls instead of a dial, a failed relay on the electronic control board or a bad control panel can prevent the compressor from getting power.
If the compressor is getting power from the cold control thermostat or the electronic control board, a failed start relay on the compressor may be keeping the compressor from running. Replace the compressor start relay if it doesn't start the compressor.
If you hear the compressor clicking constantly about every 30 seconds but the compressor motor won't run, the compressor pump may be locked up. The clicking noise is caused by the overload tripping when the motor overheats because it can't spin the locked up compressor pump. Replace the compressor if it won't run when activated. A service technician will need to replace the compressor if it's bad because that repair requires recovery and recharge of the refrigerant.
