This is a BRAND NEW 24 volt Single Pole Contactor rated at 30 amps!! It fits 99% of all Air Conditioners/Heat pumps produced.
There is no warranty and all sales are final.
Air Conditioning outdoor condensing unit or heat pump unit will not shut off. It continues to run no matter what you do. The only way you can get the outdoor unit to shut off is turn off the breaker or pull the outdoor disconnect. Also, sometimes when the contactor fails the outdoor condensing unit will not come on at all. Dirt or insects can get in between the contact points while the contactor is off, and cause the air conditioner not to come on at all. When the contactor is stuck in the "On" position (contacts welded together), Ice will form on the indoor evaporator coil and all the way out to the outdoor unit. I have seen 1 or 2 inches of ice form on the line set and outdoor unit compressor. You will not get hardly any air flow through your duct work when this happens because the evaporator has become a complete block of ice.
If this is your problem then your contactor points could be stuck, welded together causing the outdoor unit to run continuously.
Solution: You need to solve this problem by purchasing a new contactor.
Contactor's Purpose: The contactor has a 24 volt coil, when this 24 volt coil is energized from the thermostat, a call for cooling, the contacts on the contactor close, making a high voltage (220-240) connection to your compressor and outdoor fan, causing the outdoor unit to come.
*Please make sure your electrical power is off before attempting to remove or work on air conditioning equipment.
Pull the outdoor disconnect or indoor breaker that controls the air conditioner. Turn the furnace off or thermostat off so no low voltage is going through the low voltage wiring. |
