Air Conditioner Fan Not Spinning? Here’s What to Check

Sub Zero Temp Control - Air Conditioner Fan Not Spinning? Here's What to Check

When your AC suddenly stops cooling the way it should, one of the first things we recommend checking is the fan. If you find the air conditioner fan not spinning, don’t panic—but don’t ignore it either. We’ve helped plenty of homeowners around Vancouver troubleshoot this exact issue, and in many cases, the fix isn’t as complicated as it seems.

So, if your system’s acting up and you’re not sure where to start, here’s a guide that walks you through what to check, why the fan may have stopped, and when it’s time to call in the pros.


Why Is the Air Conditioner Fan Not Spinning?

Before we dive into solutions, let’s start with the basics. Your AC’s outdoor fan plays a key role in releasing heat from your home. If it stops spinning, your system can’t cool properly—and may even shut down altogether.

There are a handful of reasons this can happen. Some are simple; others might require professional repair.


Check the Thermostat First

It might seem obvious, but we’ve been called out to homes where the thermostat was accidentally turned off or set incorrectly.

Make sure the thermostat is:

  • Set to cool mode

  • The temperature is lower than the room temperature

  • The system is actually calling for cooling

If all looks good but the air conditioner fan is not spinning, it’s time to keep troubleshooting.


Look for a Tripped Breaker or Blown Fuse

Sometimes, power issues are to blame. If the breaker connected to your outdoor AC unit has tripped, the fan won’t receive any power.

Head to your breaker panel and:

  • Look for any tripped breakers

  • Reset them if needed

  • Check the fuse (if your system has one)

Be careful—if the breaker trips again right away, stop there and call us at Sub Zero Temp Control. That could signal a more serious electrical issue.


Is It a Faulty Capacitor?

This Is a Common Reason for the Air Conditioner Fan Not Spinning

The capacitor stores energy and gives the fan motor the kickstart it needs to spin. Over time, capacitors wear out—and that’s something we see a lot in older systems around Vancouver, especially during heat waves.

A worn capacitor might:

  • Cause the fan to hum but not spin

  • Cause the unit to start and stop

  • Prevent the unit from turning on at all

Please don’t try to replace this part yourself. Capacitors hold an electrical charge and can be dangerous. We’re happy to come out and test it safely for you.


Motor Problems Could Be the Culprit

If the capacitor is working but the air conditioner fan is not spinning, the motor itself might be burned out or jammed.

Fan motors naturally wear down over time, especially if:

  • The system hasn’t been serviced regularly

  • It’s running long hours during Vancouver’s warmer months

  • Debris has entered the fan housing

If the motor is the issue, it may need to be repaired or replaced. We’ll inspect the motor and let you know what’s best for your system.


Check for Debris or Physical Obstruction

Believe it or not, we’ve seen leaves, sticks, or even wasp nests block the fan from moving. Before doing anything, turn off power to the unit. Then take a look inside the outdoor fan cage and remove anything that might be caught in the blades.

Be cautious—forcing the fan can cause more damage. If the air conditioner fan is not spinning after clearing debris, give our team a call.


Is It Time for a New System?

If your system is older—say 12 to 15 years—and you’re noticing other issues like poor airflow or rising energy bills, the fan not spinning could be a sign of bigger problems.

At Sub Zero Temp Control, we’ll always look for the most cost-effective fix first. But we’ll also let you know when replacement might save you money in the long run.
