There's a tiny electrical component inside your air conditioner that's critical to its operation. The contactor is a small switch that operates similarly to a relay. Like a relay, your contactor allows a low-voltage control source to engage and disengage high-voltage power. Unlike a relay, the contactor in your AC can take power from two 120V sources and provide the necessary 240V for your compressor.
Since the contactor's job is to engage and disengage the compressor, your air conditioning system cannot function without it.
If you've recently bought your first house, you may not be familiar with air conditioning maintenance and repair. If you've always lived in apartments, then someone else handled problems with your AC.

Cold or lukewarm air coming from your vents can make for a frustrating winter night.
If your business relies on a walk-in to keep food cold, you know how disheartening it can be to step into your freezer and discover rising temperatures.

Unfortunately, complex commercial refrigeration systems have numerous potential failure points.
One possible and relatively common issue can occur with the condenser fans.

When an air conditioner is in such a condition, pinpointing the root of the problem can be a complicated task. One of the reasons why is because when an air conditioner stops getting as cold as it should, there could be several parts of the system that might be the problem.
