What causes high head pressure in a Trane Axiom GEHB Heat Pump?
- E
  Eric BrownAug 11, 2025
  High head pressure in your Trane Heat Pump can be attributed to several factors: * Trash in the chiller, which requires backflushing. * Low water flow, increase GPM. * Overcharge of refrigerant, decrease charge. * Non-condensibles in the system, evacuate and recharge. * Water too hot, decrease temperature. * Dirty filter, clean or replace. * Inadequate air flow, check, clean blower and coil.

  Robert SimpsonAug 15, 2025
  If the blower runs but the compressor doesn't in your Trane Heat Pump, consider these potential causes: * A defective compressor overload, which may need replacement (if external). * A defective compressor contactor, lockout relay, or compressor capacitor, each requiring replacement. * Low supply voltage, which needs to be corrected. * Defective windings, which means replacement. * Open limit switches, check cause/replace. * A seized compressor, try “bumping off” with start capacitor/replace.
