Resetting your residential heat pump to clear temporary error codes, resolve system lockouts, or recover from a power surge is a straightforward process performed at 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 include a breaker for the indoor air handler and a separate heavy-duty breaker for the outdoor condensing 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 and equalize pressure. Finally, switch both circuit breakers back to the "On" position and adjust your thermostat. You can verify success when normal operation resumes.
