Ac Unit Contactor Keeps Burning Out

Remove the feet from the unit by unscrewing.

Ac unit contactor keeps burning out.

It is not designed for a continuous electrical load. 2 there is no short cycle protection in the thermostst or the condenser. As a result your ac won t turn on. Since you don t want the air conditioner to fail during the hottest months of the year pay attention to these symptoms of a bad ac contactor.

Hope that your system has a low voltage fuse in the line so that it does not hurt any other components on your air conditioner. The air conditioning capacitor is designed to get the compressor and fan motors up to about 3 4 of running speed and then disengage. From the contactor disconnect the wires. Contactors pull electrical contacts apart when power is not needed and close the contacts to power something up.

Most modern t stats have the protecton built. This message has been edited by pinemarten edited 09 08 2003. All you need is a flathead screwdriver. The relay switch that sends electricity to your air conditioner s compressor is known as a contactor.

This could be a sign that the contactor has melted leaving the air conditioner with no means to block electricity. Make sure your cond. 1 the system uses or can use an option a compressor crankcase heater. If it uses one power to the ac mains power.

Fan is pulling the correct rpm s ck for a kink in. Switch off the power to the ac unit. The condenser unit never shuts off. While replacing keep in mind the specifications of the original component and replace with one which matches all those.

Contactors keep burning out. Yes the contactor coil can cause a low voltage short in a system and cause the low voltage transformer to burn out. If the contactor in your ac unit fails the compressor can t send out the refrigerant needed.
