Comfortmaker air conditioner short cycles; turns on and off frequently without reaching set temperature

Safety: Turn off power before moving thermostat wires or opening panels.

Steps:

• Check thermostat location: Ensure it is not directly in airflow from a supply register or in direct sunlight. Relocate if necessary.
• Replace filter and clean coils: Improve airflow to prevent freeze-ups.
• Observe operation: Watch for icing on the suction line or evaporator. If present, turn system off to thaw and call a technician.
• Adjust thermostat settings: Increase cycle rate or differential if available in thermostat menu.

Note: Persistent short cycling may indicate sizing or refrigerant issues that require professional evaluation.
