Where is the contactor on a goodman ac unit

You will normally find ice covering the refrigerant lines and the evaporator coil. This failure normally occurs when the silver coating wears off of the contacts.

An electric arc is created as the contacts close and without the silver coating, the contacts can be welded shut. If the contactor is sticking, it should be replaced. The contactor can fail to mechanically close if something has gotten into the mechanism to physically prevent it from closing. This usually is caused by insects or mice.

The contactor can fail electrically in one of three ways and a simple multimeter is used to check for failure. The coil can become shorted, grounded, or open. The coil can become shorted when the insulation between the wires in the coil breaks down. This can be found by shutting off the power and taking a resistance reading between the terminals on the coil. The reading should be around 20 ohms, if it is significantly less, the contactor should be replaced. The coil can become grounded when the insulation on the outer wires of the coil breaks down and allows a path to another metal component.

This can be found by taking a resistance reading from each coil terminal to the metal case of the air conditioner. A low reading means the coil is grounded and the contactor should be replaced. If the coil is open, the contactor will not close when the control voltage is applied to the coil. If the reading is significantly higher than 20 ohms, the coil is open and the contactor should be replaced. To find a replacement air conditioner contactor, you should match three things.

The first thing is the control voltage. We provide all of Contra Costa with the finest quality air conditioning. Our friendly customer service staff can assist you and make sure you are getting the Goodman parts that are compatible for your unit.
