What happens when a condenser fan motor fails?

However, a condenser (outdoor) fan-motor failure can be even worse. Since the refrigerant isn’t being condensed, it causes the pressure on the discharge side to get very high and the compressor (since it isn’t being cooled) gets extremely hot, which breaks down the internal lubricant and contaminates the system.

How much does a fan motor cost?

The average cost of a condenser fan motor is between $300 and $500 (not including installation). If the compressor breaks, you are looking at a much costlier problem which could cost up to $2000. In some cases, your fan motor may be under warranty.

What causes condenser fan to stop working?

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.

What causes outside AC fan to stop working?

One of the most common reasons fans stop spinning is because of a dead capacitor. The AC’s capacitors are small, cylinder components that send energy signals to power the fan motor and the rest of the AC unit. Capacitors can go bad over time and need to be replaced.

Can I use wd40 on AC fan?

Unscrew the top grille of the air conditioner and carefully remove the fan without disturbing the electrical connections. Most fans do not have lubrication ports, but if your fan does, place five drops of a specially made fan motor oil into the lubrication ports. Do NOT use WD-40 or other all-purpose lubricants.
