This is one of the popular questions that come across as summer rolls in. There can be numerous multitudes of possibilities (capacitor, motor, circuit boards, etc...) but here the focus of this article will be mainly on the air conditioner contactor.
In a/c breakdown cases, the capacitor and fuses are primary suspects whereas the contactor is another pretty common air conditioning part failure that is very simple in both its function and repair.
What Does the Contactor on an Air Conditioner Do to Repair it?
On your A/C unit, the contractor is a switch that allows or prevents power to the unit. At the unit, assuming everything else is properly working, there is always power but at the contactor, it sits waiting to pass to the working parts of the condenser like the motor and compressor.
The rheem air conditioner contactor is like a drawbridge similar to all the switches because nothing can pass until the bridge is closed. However, if you want to make the unit come on like you do a light, you don’t have to go out and flip this switch; but it's a switch, just a fancier version of one.
In Your, Air Conditioning Condenser Learn the Signs of a Bad Contractor
Chattering: One thing that can cause the plunger to chatter is the weak coil or a dirty contact, which indicates that it's trying to make contact but cannot fully engage as a result it starts chattering.
Melting: In the worst cases, on your contractor, you may see the plastic molding/casing getting melted. This is a final sign to tell you that there is an urgent need for replacement.
Repairing or Replacing a Contactor
A good man ac contactor can experience their common cause of failure. And even if repairs are possible, it's typically not at all worth the effort. You can even buy replacements rather inexpensively as there are no special tools that are required, and it even takes little time to do, just care.
