Condensing Unit - Thermal circuit beaker intervention

Symptoms

Thermal circuit breaker intervention

Likely Cause
  1. Low voltage at compressor
  2. Thermal circuit breaker faulty
  3. Faulty run capacitor
  4. Excessive discharge pressure
  5. High suction pressure
  6. Compressor overheated - hot return gas
  7. Electric motor - winding interrupted or in short circuit
Remedy
  1. Find and remove the cause
  2. Check characteristics and replace if necessary
  3. Find and remove the cause
  4. Check the ventilation and any restrictions or obstructions in the system circuit
  5. Check the sizing of the system. Replace the condensing unit with more powerful one
  6. Check the refrigerant charge, repair any leaks and add gas
  7. Replace the compressor
