Six Reasons for a Broken Heat Pump Fan in Saukville, Wisconsin

Heat pumps are different from furnaces because they do not create heat but instead move it from one place to another. In that sense, the fan is a crucial element without which the heat pump is ineffective. You can tell your fan is broken if you hold your hand up to your vents and don’t feel any hot or cold air coming out.

Below are some common reasons why your heat pump fan is malfunctioning. 

1. Broken Blower Motor

The most obvious reason your fan is broken is because of blower fan motor failure. The blower motor turns on the fan that pushes hot and cold air out of the vents in your home, so when the blower motor is broken, air flow effectively stops. The motor usually makes a slight droning sound when on, so you can tell it is broken if your heat pump is silent. 

2. Electrical Issue

Another potential reason for a heat pump fan not spinning in Saukville is electrical issues. Fan motors draw a lot of electricity and can malfunction if there is a problem with the motor’s circuit board or wiring.

There could also be an electrical issue with your thermostat preventing it from turning the fan on and off. In some cases, the problem could be due to issues with your home’s entire electrical supply in which your heat pump doesn't get any power at all. High usage during the winter can contribute to excess system stress and electrical issues. 

3. Capacitor Problem

A capacitor is a special electrical device housed in your fan array that causes the blades to turn. Specifically, the capacitor is what provides the initial electrical energy to start the rotators spinning. If the capacitor shorts out, the result may be that the fan blades can no longer spin.

You can test the fan capacity at home using a multimeter. In general, your heat pump should have a volt reading somewhere between 350 and 440.

You can check your unit manual to see what the exact required capacitor voltage should be. If the capacitor is damaged, you will need an expert to replace it. 

4. Frozen Coils

Frozen coils may also be the culprit for a heat pump fan not spinning. When coils become frozen, they can block crucial airflow that regulates the system’s internal temperatures. If things get too hot, your heat pump might shut down automatically to prevent any damage to the system’s components. 

5. Dirty Fan Blades

Another possible cause for a heat pump fan not spinning is dirt and grime on the blades. Debris accumulation weighs the fan blades down, putting extra pressure and strain on the motor. If it runs for too long with heavy blades, the motor might eventually short out or not be able to spin the blades.

Dirt and grime on the blades can also get into the fan motor and clog its internal components, making spinning much harder. 

6. Tripped Circuit Breaker

If your fan shuts off randomly when you turn your system on, it could be due to your circuit breaker. Most homes have their HVAC system on a separate, dedicated breaker that can shut off if there is an issue. If the breaker itself is damaged, it might trip and shut the heat pump off even when nothing is actually wrong.

Check your electrical panel and see if the circuit switch for your heat pump is tripped. If it is, you can turn it back in the on position to see if it fixes the problem.
