How Can I Reset My Air Conditioner to Fix Power Issues?

Turn the thermostat to Off, shut the AC breaker off, wait 5 minutes, then turn the breaker and thermostat back on to Cool. This resets many systems after a power blip. If it trips again, stop and schedule service.

Quick steps:

• Set thermostat to Off and fan to Auto.
• Switch the outdoor AC disconnect or breaker Off for 5 minutes.
• Replace thermostat batteries if used.
• Check the condensate safety switch (clear a full drain pan).
• Restore power and restart cooling.
