Compressor Not Starting
Symptom
Payne air conditioner blows warm air immediately after starting, with no initial cool period.
Compressor Not Running or Reversing Valve Stuck (Heat Pump)
Symptom
Payne air conditioner is very loud outside, with a noticeable high-pitched whine or roar.
Noisy Compressor or Fan
Symptom
Payne air conditioner occasionally emits a hissing sound near the indoor coil or line set.
Refrigerant Flow Noise / Possible Leak
Symptom
Payne air conditioner runs but does not cool the house adequately; supply air is only slightly cooler than room temperature.
Low Refrigerant Charge / Refrigerant Leak
Symptom
Payne air conditioner runs but makes a loud grinding or squealing noise from the indoor unit.
Blower Wheel or Motor Bearing Failure
Symptom
Payne air conditioner runs continuously and rarely shuts off, even when the set temperature is reached.
Thermostat or Capacity Control Issue
Symptom
Payne air conditioner starts but shuts off after a few seconds to a minute, repeatedly.
Thermal Overload / Safety Trip
Symptom
Payne air conditioner trips the breaker immediately or shortly after starting.
Overcurrent / Short Circuit
Symptom
Payne air conditioner will not turn on at all; no outdoor or indoor operation when calling for cooling.
No Power / Control Circuit Failure
Symptom
Payne outdoor unit frequently turns on and off (short cycling), running for only a few minutes at a time.

Symptom
Payne outdoor unit hums but the fan does not spin; compressor may or may not start.
Failed Condenser Fan Motor or Fan Capacitor
Symptom
Payne outdoor unit makes a loud rattling or vibrating noise during operation.
Mechanical Vibration / Loose Panels or Fan Imbalance
Symptom
Payne outdoor unit runs but indoor blower does not; coil may freeze and little or no air comes from vents.
