How To Troubleshoot a Heat Pump That’s Not Working Properly

February 3, 2025

Is your heat pump acting up and failing to provide comfort? A malfunctioning heat pump can be frustrating, especially when the cold weather sets in. Understanding how to troubleshoot a heat pump that’s not working properly can help you quickly identify the issue and restore comfort. 

Five Common Heat Pump Issues and Troubleshooting Tips

Here are some common tips that you can follow to locate the source of your heat pump troubles:

1. Checking the Power Supply

Power issues are one of the most common causes of malfunctions. If the system isn’t turning on, ensure it’s connected to a power source and the circuit breaker hasn’t tripped. Inspect the wiring and connections for any visible damage if the power is on.

2. Inspecting the Thermostat

The thermostat regulates your system’s temperature and operation. If it’s not functioning properly, the performance will suffer. Ensure it’s set correctly and not obstructed by debris. If the thermostat is unresponsive, replace the batteries or recalibrate it. Confirm that it’s communicating with the system properly.

3. Compressor and Cycle Problems

The compressor is a critical component. If it’s faulty or not cycling correctly, the system will fail. You might hear unusual noises or notice it’s not switching between heating and cooling modes. A professional must inspect and repair the compressor in such cases.

4. Fan and Defrost Cycle Issues

A malfunctioning fan or defrost cycle can hinder your system’s efficiency. If the fan isn’t running or makes strange noises, there could be an issue with the motor or airflow. The defrost cycle helps remove frost buildup from the outdoor unit, especially in cold weather. If it’s not functioning properly, the system may not work effectively. Ensure no obstructions are blocking the fan or defrost cycle, and clean the outdoor unit.

5. Troubleshooting the Defrost Cycle

The defrost cycle prevents ice buildup on the outdoor unit. If the system keeps icing over, the defrost cycle might not work. Check for ice accumulation and turn off the unit to let the ice melt. If the problem persists, it’s time to call a professional for inspection.

To prevent future issues, schedule regular maintenance for your system. Cleaning filters, checking refrigerant levels, and lubricating moving parts ensure your system operates efficiently, providing long-term comfort throughout the year.
