Possible Causes

Faulty temperature sensor, Incorrect ambient conditions, Control board relay fault, Overheating due to dirty condenser

How to Fix / Troubleshooting

Safety first: Disconnect power before cleaning or testing sensors.

  • Clean condenser coil: Remove dust and debris from the condenser to prevent overheating and high‑pressure trips.
  • Check ambient temperature: Ensure the unit is not installed in an area outside the specified temperature range.
  • Test temperature sensors: Measure resistance of the evaporator and cabinet NTC sensors and compare to Gram specifications. Replace any sensor that is out of range.
  • Control board inspection: If sensors and condenser are fine, the compressor relay on the PCB may be failing, causing rapid cycling. Replace the main control PCB if necessary.
