To Next PageTo Next PageWhat to do if my Trane GEVE Heat Pump has no response to thermostat settings?
If your Trane Heat Pump isn't responding to thermostat settings, the possible causes include: the main power being off (check fuses), a defective control transformer (replace it), broken or loose connections (repair them), a defective thermostat (replace it), or a transformer issue (reset the transformer).
What to do if my Trane Heat Pump compressor does not run, but the blower does?
If the blower runs but the compressor doesn't in your Trane Heat Pump, it could be due to a defective compressor overload (replace if external), a defective compressor contactor (replace it), supply voltage being too low (correct it), a defective compressor capacitor (replace it), defective windings (replace them), or limit switches being open (check cause/replace or repair).
What to do if my Trane Heat Pump unit short cycles?
If your Trane Heat Pump is short cycling, it may be because the thermostat or sensor is improperly located. If this is the case, relocate them.
Why is my Trane GEVE Heat Pump not providing enough capacity?
Insufficient capacity in your Trane Heat Pump can stem from several issues: a dirty filter (replace or clean it), blower RPM being too low (correct it), leaks in the ductwork (repair them), introduction of excessively hot or cold return-air (correct this), low refrigerant charge (locate the leak, repair, and recharge), a restricted thermal expansion valve (replace it), a defective reversing valve, an improperly located thermostat (relocate it), an undersized unit (recalculate heat gains/losses), inadequate water flow (increase GPM), scaling in the heat exchanger (clean or replace it), water being too hot or too cold (adjust the temperature), or a blocked filter drier (replace it).
Why does my Trane Heat Pump have high head pressure?
High head pressure in your Trane Heat Pump may be due to trash in the heat exchanger (backflush it), low water flow (increase GPM), an overcharge of refrigerant (decrease the charge), non-condensables in the system (evacuate and recharge by weight), water being too hot (decrease the temperature), a dirty filter (clean or replace it), or inadequate air flow (check and clean the blower and coil).
Why is the high pressure switch open on my Trane GEVE?
If the high pressure switch is open on your Trane Heat Pump, possible causes include inadequate GPM (increase water flow to unit), water being too hot (decrease temperature), inadequate air flow (check and clean blower and coil), a dirty filter (clean/replace), being overcharged with refrigerant (decrease charge), or a defective pressure switch (check or replace).
Why is the low pressure switch open on my Trane Heat Pump?
If the low pressure switch is open on your Trane Heat Pump, it could be due to inadequate GPM (increase GPM), water being too cold (increase temperature), inadequate air flow (increase CFM), a dirty filter (clean/replace), being undercharged with refrigerant (increase charge), a defective pressure switch (replace it), or the heat transfer fluid being too cold (raise water temperature).
Why does my Trane GEVE have low suction pressure?
Low suction pressure in your Trane Heat Pump can be caused by being undercharged (locate leak, repair and recharge), a restricted thermal expansion valve (repair / replace), inadequate air flow (check, clean blower and coil), a dirty filter (clean/replace), or inadequate GPM (increase GPM).
