Does a heat pump fan run in the winter?
Should My Heat Pump’s Outdoor Unit Run During Cold Weather? If you’ve only experienced a house that is cooled by an air conditioning unit, then you may find it odd that your heat pump fan is running in cold weather. That is normal, and your heat pump fan should be spinning.
Why is the fan not turning on my heat pump?
If the compressor is running but the fan is not, the cause is either a bad fan motor or a burned out capacitor. But first, check for debris! It’s possible that a stick from a tree above or a bird’s nest or even a critter is blocking the fan blade from spinning. It happens.
What causes a condenser fan to not turn on?
Capacitor Problems
The capacitor stores energy that is used to power your air conditioner’s fans. There are several reasons the capacitor of your HVAC unit can fail. These include overheating, running too long, power surges, and age. When the capacitor fails, the condenser fan will no longer rotate.
Why doesn’t my heat pump work when it’s cold?
Your Auxiliary heat strips or back up heat may be undersized or not working at all. During extreme cold temperatures, a heat pump system uses heat strips to compensate when the system cannot maintain a set temperature.
Can a heat pump run without the fan running?
Do not run your heat pump without a working fan as that could cause damage to the compressor. A damaged compressor can lead to a very costly repair bill or replacement of the entire system.
Should fan be on AUTO or on in winter?

What do you do when your heat pump freezes in the winter?
Heat Pump Defrost Cycle
The unit is equipped with temperature sensors which trigger the defrost function. These cycles usually only last 10 to 15 minutes, depending on the conditions. Yet the brief defrost cycles should be enough to keep the unit functioning efficiently throughout the winter.
Why is my blower fan not working?
If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn’t working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.
How do I know if my heat pump is working in the winter?
Checking Without Gauges
- Check the discharge (vapor) line, it should be 100˚ – 110˚ over the outdoor ambient temperature.
- Suction line Temp should be 5˚ – 15˚ cooler than the outdoor temperature.
- Liquid Line should be 3˚ – 15˚ warmer than the indoor temperature.
What temperature should I set my heat pump in the winter?
Ideal Winter Heat Pump Temperature Settings
According to the Department of Energy, 68°F is the sweet spot that balances comfort and energy efficiency during the fall and winter months. When your home is occupied and when family members are awake, a heat pump setting of 68°F keeps the living areas reasonably warm.
At what temperature does a heat pump freeze up?
32 degrees
When the temperatures drop below 32 degrees, the condensation freezes, creating a layer of ice on your outdoor heat pump unit.
Why is my heat pump outside unit not running?
One of the most common problems is blown fuses or flipped circuit breakers. If your unit is not working, make sure to check your fuses and circuit breakers. It could be as easy as a flip of a switch.

On-Off: When your outside AC unit is not running, sometimes it’s as simple an on/off switch being accidentally turned off. Most outside fan units have an on-off switch in a small box by the unit. Circuit breaker tripped: A circuit breaker could have been the cause of your outside AC unit to stop working properly.
How do I reset my outside heat pump?
Reset the system by turning it off with the thermostat or breaker if your unit has a safety device locking it out. Wait 60 seconds and turn it back on. It may take up to 10 minutes for the outdoor unit to start.

The condenser unit won’t turn on: If your condenser unit won’t turn on at all, you may have a faulty motor or the unit may not be receiving power. Examine all wiring and ensure that the unit is plugged in.
Do condenser fans always run?
When the fan is switched to the “on” position, it will run continuously. It should be set to the “auto” position, so it only runs when the air conditioner is running. AC is too small for the property or can’t keep up with extreme temperatures.
Why is my compressor fan not working?
If the compressor is working, but the fan won’t turn, then the problem is most likely with the motor and/or capacitor. If you don’t hear any sounds to indicate that the compressor is working, and the fan isn’t spinning, the most common causes are a lack of power or a faulty compressor contactor.
