Problems Causing a Heat Pump Fan Running Constantly
There are several reasons why a heat pump fan might run constantly in the winter. Some of the most common reasons include:
- Dirty or clogged air filters: Heat pump fans rely on a steady flow of air to operate properly. If the air filters are dirty or clogged, it can restrict the flow of air through the system and cause the heat pump fan to run constantly. To fix this issue, simply replace the air filter.
- Frozen outdoor unit: In cold weather, the outdoor unit of a heat pump can become frozen. This can prevent the heat pump from functioning properly and can cause heat pump struggles which is why the fan will run continuously. To fix this issue, you will need to defrost the outdoor unit by running the defrost cycle and allowing it to thaw. Resolve any issues that could increase the outdoor unit’s risk of freezing, such as leaking overhead gutters.
- Incorrect thermostat settings: When the thermostat’s fan setting is set to AUTO, you’ll notice the heat pump fan only runs during heating cycles. If the fan is set to ON, you’ll notice the heat pump fan running constantly, even when the heat pump is not actively heating. If the thermostat is not set properly, it can cause the heat pump fan to run constantly. To fix this issue, make sure the fan is set to AUTO.
- Faulty blower relay switch: If the blower relay switch is faulty, your thermostat setting may not be properly communicated to the heat pump system and it can leave the heat pump fan running constantly. To fix this issue, you will need to have the relay switch replaced by a qualified technician.
Best Practices for Winter Heat Pump Use
Here are some best practices for running your heat pump during the winter that will improve heating efficiency and protect your HVAC equipment:
- Keep the air filter clean: To ensure that your heat pump is running efficiently and effectively, it is important to keep the air filter clean. Clean or replace the air filter on a regular basis to prevent them from becoming clogged.
- Keep the outdoor unit clear: The outdoor unit of a heat pump should be kept clear of snow, ice, and other debris. This will ensure that the heat pump is able to receive the airflow it needs to function properly and prevent the blower fan from running constantly.
- Install a programmable or smart thermostat: A programmable or smart thermostat can help you save energy and money by setting the temperature in your home to match your schedule. The heat pump won’t have to work as much, which saves energy and reduces wear and tear on the equipment.
- Have the heat pump serviced regularly: To ensure that your heat pump is running at its best, it is important to have a maintenance tune-up performed by a qualified technician at least twice per year. This will help to prevent costly repairs and ensure that your heat pump is providing maximum comfort and efficiency.
