Status LED Description Status LED Troubleshooting
Supply voltage is present at module terminals
1. Compressor internal overload is open
2. Broken wire or connector is not making contact
3. Low pressure switch open, if present
4. Compressor contactor has failed open
1. Low refrigerant charge
2. Evaporator blower is not running
3. Evaporator coil is frozen
4. Faulty TXV
5. Condenser coil is dirty
6. Liquid line restriction (filter drier blocked if present in system)
7. Thermostat is malfunctioning
