Resetting a residential heat pump to clear temporary error codes or resolve system lockouts is a straightforward process performed through your home's electrical panel. First, go to your wall thermostat and switch the system mode setting to "Off." Second, go to your main electrical service panel and locate the circuit breaker switches dedicated to your HVAC system, which typically include a breaker for the indoor air handler and a separate heavy-duty breaker for the outdoor condenser unit. Flip both circuit breakers fully to the "Off" position. Third, wait at least five full minutes to allow all internal electrical components, relays, and capacitors to fully discharge. Finally, switch both circuit breakers back to the "On" position, wait a few minutes for power to stabilize, and adjust your thermostat to your desired heating or cooling setting. You can verify success when the system resumes normal operation.
