Possible Causes
Faulty main control board cooling relay, Open compressor start circuit, Failed Peltier module, Incorrect temperature sensor reading preventing cooling
How to Fix / Troubleshooting
Safety: Unplug the unit before accessing electrical components.
- Verify setpoint: Ensure the set temperature is below the current cabinet temperature so the unit should be calling for cooling.
- Listen for compressor or Peltier: If only the fan runs, the cooling device may not be energized.
- Inspect control board: Remove the control panel or rear cover to access the main board. Look for burnt relay contacts or damaged traces.
- Check compressor start components or Peltier wiring: Ensure all connectors are secure and wires are intact.
- Sensor check: A faulty thermistor reading too low can prevent cooling. Test and replace the cabinet thermistor if necessary.
- Replace failed parts: Install an OEM Avanti main control board, compressor start relay, or Peltier module as indicated by diagnostics.
