Freezer Won't Start
If your freezer won't start, the problem could be caused by a power supply issue, faulty temperature control, defective start relay, or a failed compressor. Before replacing any parts, inspect the most common causes listed below.
Safety Notice: Always unplug the freezer before servicing it. If you notice burning odors, damaged wiring, or signs of electrical failure, discontinue use until the problem has been properly inspected.
Possible Causes
- No power supply
- Temperature control set incorrectly or faulty
- Defective start relay
- Failed overload protector
- Faulty thermostat or cold control
- Failed compressor
- Damaged power cord
- Defective electronic control board
1. No Power Supply
Most Common Solution
If the freezer is not receiving power, it will not start. A tripped circuit breaker, blown fuse, faulty outlet, or loose power cord is one of the most common causes.
What to do:
- Verify the freezer is plugged in securely.
- Test the outlet with another appliance.
- Check your home's circuit breaker or fuse box.
- Restore power and try starting the freezer again.
2. Temperature Control
The freezer will not start if the temperature control is turned off or if the control has failed.
What to do:
- Verify the temperature control is set to a cooling setting.
- Adjust the control to a colder temperature.
- Replace the control if it does not respond properly.
3. Start Relay
The start relay provides power to the compressor during startup. If it fails, the compressor may click repeatedly or fail to start altogether.
What to do:
- Disconnect power to the freezer.
- Inspect the start relay for signs of damage.
- Replace the relay if it rattles when shaken or fails continuity testing.
4. Overload Protector
The overload protector protects the compressor from overheating. If it fails, the compressor may not receive power.
What to do:
- Allow the compressor to cool if it has overheated.
- Test the overload protector for continuity.
- Replace it if it is defective.
5. Thermostat or Cold Control
A faulty thermostat or cold control may fail to signal the compressor to start.
What to do:
- Rotate the thermostat while listening for a click.
- Test the thermostat for continuity.
- Replace it if it does not function properly.
6. Compressor
If the compressor has failed internally, the freezer will not start or cool properly.
What to do:
- Listen for humming or clicking from the compressor.
- Have the compressor tested if the start components are working correctly.
- Replace the compressor if it has failed.
7. Power Cord
A damaged power cord can prevent electricity from reaching the freezer.
What to do:
- Inspect the cord and plug for cuts, burns, or other damage.
- Replace the power cord if it is defective.
8. Electronic Control Board
On electronically controlled models, the control board supplies power to various components. If it fails, the freezer may not start.
What to do:
- Inspect the control board for burned components or visible damage.
- Replace the board after ruling out the power supply and start components.
