What happens if the condenser fan fails?
When the condenser overheats, all of the components of the AC system will begin to overheat until they eventually get hot enough to burn and emit an odor. A failed fan will not only fail to produce cold air, but can even result in damage to the AC system due to overheating.
What does a bad condenser fan sound like?
There’s a rattling or buzzing noise coming from the condenser unit when the fan is turned on. If you hear a loud rattling noise, it could be a minor issue like loose stones or debris that’s caught in the condensing unit.

What happens if the condenser is blocked by dust?
With a condenser coil that is dirty or blocked, the unit will have to work harder to achieve the same results. A dirty condenser coil with have a reduced ability to transfer heat to the outside air and this can lead to a less effective cooling system.
What are the symptoms of a dirty evaporator coil?
Symptoms of a Dirty Coil
- Air Conditioning Loses Cooling Capacity. One thing that will be noticeable when the evaporator coil is dirty is that your AC won’t produce air that’s as cold as it should be.
