Possible Causes

Failed compressor inverter board, Loose inverter-to-compressor connector, Faulty main control board compressor output, Internal compressor electrical fault

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator. Do not open the sealed system.

Identify inverter-equipped model: Some Insignia refrigerators use an external inverter module mounted near the compressor.

  • Inspect inverter module: Check for burnt smell, discoloration, or cracked housing.
  • Check connectors: Ensure the power input and compressor output connectors on the inverter are fully seated.
  • Power reset: After reseating connectors, restore power and see if the compressor starts and the E15 code clears.
  • Replace inverter module: If the compressor does not start and other components are normal, replace the inverter board with an Insignia-compatible part.

Warning: Diagnosing inverter and compressor faults requires high-voltage measurements and specialized tools. If you are not experienced, contact a professional technician.
