Key Takeaways

  • A reset may clear a heat pump lockout without fixing its cause.
  • Check the model’s instructions, record the fault and arrange service if the warning returns.
  • A recurring lockout needs investigation rather than a sequence of repeated resets.
  • Thermostat settings and building notices provide useful context for a heat pump fault.

In This Guide

Intermittent short-cycling needs investigation. A permitted reset may clear a lockout, but repeated restarting does not correct the cause.

The video illustrates one installation. Follow the instructions for your installed model rather than assuming every condo heat pump uses the same reset procedure.

Why You Should Reset Your Heat Pump

A heat pump may stop or display a warning when operating conditions fall outside its requirements. Record the indication and seek diagnosis if the fault persists or returns; clearing a code does not prove that the equipment is working correctly.

8 Step Guide To Reset Your Heat Pump

Here’s how you can reset your heat pump in a few easy steps:

1. Turn Off The Thermostat

First things first—turn off the thermostat. This prevents the system from continuing to function while you reset it, ensuring the unit will restart properly once everything is powered back on.

2. Turn Off The Power Switch

Next, locate the heat pump’s power switch toggle. This switch is typically located on the edge of the unit or on the wall next to it. Turn this switch off to completely disconnect the system’s power.

3. Turn Off The Electrical Breakers

Use only the reset procedure specified for your installed model. Power arrangements and the number of breakers vary; do not operate unidentified breakers or open electrical panels.

4. Turn Everything Back On

Now it’s time to power everything back up in reverse order:

  • Restore power only as directed by the installed model’s permitted reset procedure. Do not repeatedly reset a breaker that trips.
  • Next, flip the power switch toggle near the heat pump back to the “On” position.
  • Finally, turn the thermostat back on and set it to the desired temperature.

5. Adjust The Thermostat

Select the appropriate available mode using the normal thermostat controls. For heating, the setpoint is above room temperature; for cooling, it is below room temperature.

  • Cooling Mode (Summer): Set the thermostat to cooling mode if you’re resetting during warmer months.
  • Heating Mode (Winter): For colder months, switch it to heating mode.

Give the system about 15 minutes to stabilize and begin running as expected.

6. Check Airflow

Place your hand near the vent to make sure the air is flowing correctly. 

8. Verify Heating Or Cooling

Observe airflow and comfort from the normal occupied area. Do not touch the coil or reach into the equipment to test temperature. Report continued poor heating or cooling to a qualified technician.

When Should You Reset Your Heat Pump?

Interpret fault indicators using the installed model’s documentation. An LPS or HPS warning needs attention to its cause, and a green light alone does not prove that every part of the system is working correctly. Arrange assessment for persistent symptoms.

Note: If you have a Jonson Control Heat Pump, a constantly flashing red light resembling a heartbeat is normal. However, if the red light flashes at a different rate, it indicates that you should schedule a service call for your unit.

Resetting your system can also help resolve issues like:

  • Power surges or brief electrical interruptions
  • Dirty air filters, which may cause restrictions and overheating
  • Control board errors due to sensor malfunction.

By following these simple steps, you can reset your heat pump and potentially avoid an unnecessary service call. However, if the issue persists after a reset, a professional inspection may be needed.

Questions About This Guide

Will resetting a heat pump repair the underlying fault?

A reset can clear a lockout, but it does not repair an airflow, refrigeration, electrical or building-loop problem. Arrange diagnosis if the warning returns.

What should I record before a heat pump reset?

Record the fault indication, operating mode and equipment model. Follow the installed model's instructions for any permitted reset and avoid internal electrical or refrigeration work.
