Payne outdoor unit frequently turns on and off (short cycling), running for only a few minutes at a time.

Safety: Most checks are low-risk, but avoid opening electrical compartments with power on.

• 1. Check thermostat placement: Ensure the thermostat is not in direct sunlight, near a supply register, or near heat-generating appliances. If it is, consider relocating it with professional help.
• 2. Replace air filter: A clogged filter can cause coil freezing and short cycling. Install a clean filter and monitor operation.
• 3. Observe outdoor unit: Watch the condenser during operation. If it shuts off due to pressure switch trips (clicks, then restarts after a few minutes), there may be airflow or refrigerant issues.
• 4. Check for icing: Inspect the indoor coil and suction line for ice. If present, shut the system OFF and run the fan to thaw, then call a technician to check refrigerant charge and airflow.
• 5. Professional evaluation: If short cycling persists, a technician should verify system sizing, check pressure switches, and inspect the control board and thermostat wiring.
