Possible Causes

Failed compressor start relay, Open thermal overload, Defective compressor, Failed thermoelectric (Peltier) module on some Luma models

How to Fix / Troubleshooting

Unplug the unit before accessing the rear compartment.

  • Listen for operation: When powered, you should hear a low hum from the compressor or a fan near a thermoelectric module. Silence suggests a start issue.
  • Check start components: Remove the rear panel and inspect the compressor start relay and overload. Replace with a Luma compressor start device kit if they are burned or rattling.
  • Thermoelectric models: If your Luma uses a Peltier module, inspect the module and its heatsinks for damage and ensure the module fan runs. Replace a cracked or burned Luma thermoelectric cooling module.
  • Test again: After replacing start components or module, restore power and allow 30–60 minutes to see if cooling begins.

If the compressor receives proper voltage but does not start, it is likely failed and requires professional replacement.
