Why Is My Heat Pump Fan Not Spinning?
Heat pumps offer energy-efficient alternatives to traditional heating and air conditioning systems. They can either heat or cool your space in a single compact unit. Like most devices, heat pumps feature several moving parts that contribute to their overall functionality.
When a single component of your heat pump stops working, you could end up in an uncomfortable indoor space. For example, your heat pump fan not spinning should raise alarm.
As the go-to contractor for HVAC repair in Boca Raton, our Cool By Design Inc crew delves deeper into how heat pumps work and the typical reasons your heat pump fan may stop spinning.
When Should the Heat Pump Fan Run
Most heat pumps comprise an indoor air handling unit and an outside unit. They utilize a refrigeration cycle to transfer heat between an indoor and outdoor environment.
You should notice your heat pump fan not spinning when the unit is off or the air handler has no air coming out of it. The indoor and outdoor units work in tandem.
Therefore, your heat pump fan should spin when you want air indoors and shouldn’t spin when your indoor temperature matches the thermostat setting.
Common Causes of Heat Pump Fan Issues
The moving parts of every machine gradually sustain wear. That said, you want to keep a watchful eye on your heat pump’s functionality and hire a professional to inspect it every so often. After years of use, your heat pump fan might call it quits from normal wear and tear.
In such situations, you really can’t do anything to stop that from happening. If you find your heat pump fan not spinning, the following reasons could be to blame:
Debris Blockage
Outside debris can get into your system and clog it. Clearing out any dirt, leaves, and other debris may restore your fan to proper working condition. To do this, turn off the power to your heat pump, then take off the unit’s top part.
If you see anything lodged in the fan, use a stick or tool to remove it. Never stick your fingers in a fan. It also helps to maintain a clear area around your heat pump year-round to prevent unwanted items from falling into your unit and damaging the fan or other components.
This means trimming bushes or trees that hang over the unit. You should also keep your heat pump clean and well-maintained. Check the filter once a month and swap it out whenever it gets clogged or dirty.
Every two to three months, spare some time to clean the fans and coils.
A Lagging Motor
Sometimes you can push start the fan by giving the blades a push with a stick or tool. If the blades start moving, that points to a fan motor on its last legs that could benefit from a prompt replacement.
Dead Motor or Capacitor
If trying to move the fan with a stick or tool doesn’t work, you may have a dead capacitor or motor on your hands. If you’ve worked with electrical systems and know how to use a multimeter, testing a capacitor should be a breeze.
Alternatively, reach out to an HVAC professional to diagnose and fix the problem. Don’t run your heat pump without a working fan as that could damage the compressor, consequently leading to costly repairs that may force you to replace the entire system.
Thermostat Problems
Sometimes you may notice your heat pump fan not spinning because of an accidental or intentional change in thermostat settings. If so, adjust your thermostat to the correct setting and temperature and see if that solves the problem.
Power Supply Issues
If you notice your heat pump fan not spinning in cold weather, the chilly temperatures may have forced it to overwork, tripping the circuit breaker. Resetting the breaker and powering the device back on should fix the issue.
