How to Reset Heat Pump

Does a Heat Pump Have a Reset?

A heat pump is a valuable and energy-efficient HVAC system that provides both heating and cooling for your home. Like many electronic devices, heat pumps do have a reset function that can be useful in troubleshooting certain issues. In this comprehensive guide, we’ll explore the heat pump reset function, when to consider resetting your heat pump, the importance of identifying underlying problems, and how to troubleshoot a heat pump that won’t turn back on. We’ll also cover the steps to get your heat pump to kick on, the process of resetting your HVAC system, and essential tips to avoid common mistakes during the reset process.


Understanding the Heat Pump Reset Function

The reset function on a heat pump serves as a diagnostic tool to address specific performance issues. When activated, it resets the system’s controls and settings to their original state, often clearing minor glitches or error codes. However, it’s crucial to use the reset function judiciously and identify when it’s appropriate to reset your heat pump.


When to Consider Resetting Your Heat Pump

Before performing a reset, it’s essential to recognize the signs that may indicate the need for one. Common scenarios that might warrant a reset include:

  • Heat pump fails to start: If your heat pump is unresponsive and there are no apparent issues with power supply or thermostat settings, a reset may help.
  • Unusual performance: If your heat pump is operating inconsistently or performing below its usual standards, a reset could be considered.
  • Error messages: If the control panel displays error codes or warning messages, a reset might be necessary to clear the faults.

Importance of Identifying the Underlying Problem

While resetting the heat pump can be a useful troubleshooting step, it’s essential to understand that it may only address surface-level issues. It won’t fix the root cause of more significant problems. Properly diagnosing the underlying issue is crucial to determine whether a reset is sufficient or if further troubleshooting or professional assistance is needed.


Why Won’t My Heat Pump Turn Back On?

When your heat pump refuses to start, it can be a cause for concern, especially during extreme weather conditions. Several factors could be causing this problem, and it’s essential to investigate the possible reasons before attempting a reset.


Possible Reasons for Heat Pump Failure to Start

Power supply issues: Check for tripped circuit breakers, blown fuses, or disconnected power supply that might prevent the heat pump from turning on.


Thermostat problems: Ensure that the thermostat is set correctly and functioning properly. A malfunctioning thermostat can hinder the heat pump’s operation.


Faulty components: Malfunctioning sensors, motors, or compressors can also lead to the heat pump’s failure to start.


Troubleshooting Steps Before Resetting

Before resorting to a reset, go through some basic troubleshooting steps to rule out simple issues:


Verify thermostat settings: Check that the thermostat is set to the appropriate temperature and mode (heating or cooling).


Inspect air filters: A clogged air filter can hinder the heat pump’s operation, so ensure the filters are clean and free from debris.


Check outdoor unit: Inspect the outdoor unit for debris, ice buildup, or other obstructions that might affect airflow and cause the heat pump to malfunction.


Signs That a Reset Might Be Necessary

If the basic troubleshooting steps don’t resolve the issue and you’ve ruled out other possible causes, there are some indicators that a reset might be necessary:


The heat pump displays error codes or unusual messages on the control panel.


The heat pump has experienced a power surge or blackout recently.


The heat pump has been running continuously without achieving the desired temperature.


How Do I Get My Heat Pump to Kick On?

If you’ve determined that a reset is necessary, follow these steps to get your heat pump back on track:


Basic Troubleshooting Tips for Heat Pump Activation


Ensure the thermostat is set to “Off” or the lowest temperature setting before attempting a reset.


Turn off the circuit breakers that supply power to the heat pump. It’s advisable to turn off both the indoor and outdoor unit’s breakers.


Wait for at least five minutes to allow the system to fully power down.


Checking Thermostat Settings for Proper Operation

After the waiting period, check the thermostat settings to ensure they are appropriate for your heating or cooling needs.


Ensuring Adequate Power Supply

Turn on the circuit breakers for the heat pump, both indoor and outdoor units. Wait a few moments to see if the heat pump starts up. If it does, monitor its performance to ensure everything is functioning correctly.


If your heat pump fails to start, it is a common situation and is usually easy to fix. However, many homeowners are not aware of how to troubleshoot the issue, so they end up calling professionals to fix problems they could have resolved themselves. Some of the problems that homeowners can easily handle include:


Improper thermostat settings.

Tripped emergency switch.

Blown fuses in the electrical panel box.

Tripped or turned off circuit breakers.

Tripped outdoor reset switch.

How long does it take to reset a heat pump?

You can reset the heat pump by turning off the equipment using the thermostat or circuit breakers. After a short period, turn it on again. The outdoor unit may take up to 15 minutes to restart.

How to reset the heat pump?

Resetting the heat pump can be a simple or challenging task depending on the cause of the problem. You can attempt to reset the heat pump yourself or seek help from an HVAC (heating, ventilation, and air conditioning) expert. You can also contact the manufacturer to get the best heat pump repair service in Florida Lake City.


To reset the heat pump, follow these steps:


Check the thermostat and turn it off.

If you need to reset the heat pump because it keeps shutting off or fails to perform the desired functions, resetting the thermostat is the best option. The first step is to check the settings on the thermostat and make adjustments.

The heat pump has two main objectives: to heat your home or to cool your space. If it’s set to heat and you want cooling or vice versa, adjust the thermostat accordingly. If the issue persists, contact a heat pump repair center in Florida Lake City.


Check the power and turn off the power switch.

If your heat pump is not working properly, check if it has sufficient power. Perhaps someone turned off the power switch, cutting off the power supply to the heat pump.

The heat pump is equipped with various circuit breakers to regulate the power supply. There are two circuit breakers: one for the condenser and the other for the air handler. Both circuit breakers should be in the ON position. If they are not, turn them on.


Turn off both circuit breakers.

Now that you have turned off the thermostat and power switch, turn off the circuit breakers for the air handler and condenser. Wait a few minutes, and then proceed to the next step.

DIY Resetting vs. Professional Help

While a basic reset can often be done by homeowners, more complex issues may require professional help. If you’re unsure about the cause of the problem or how to perform a reset safely, it’s best to contact an HVAC technician.


Common Mistakes to Avoid During the Reset Process

When attempting a reset, avoid these common mistakes to prevent further damage to your heat pump:


Resetting multiple times in quick succession without identifying the underlying problem.


Ignoring error codes or warning messages displayed on the control panel.


Skipping basic troubleshooting steps before attempting a reset.



Resetting a heat pump can be a useful troubleshooting step to resolve minor issues and restore proper operation. However, it’s essential to understand when a reset is appropriate and to identify the underlying problem if one exists. Regular maintenance and timely professional assistance will help keep your heat pump in optimal condition, ensuring efficient and reliable performance year-round. If you encounter persistent issues or are unsure about performing a reset, don’t hesitate to seek help from an HVAC expert for a thorough diagnosis and resolution. Remember that proper care and attention will keep your heat pump running smoothly, providing you with the comfort you need in every season.
