Condenser Only Coming On Outside When I Reset House Breaker
Posted: Tue Sep 22, 2009 8:56 am
The problem started a few days ago when I noticed that the air coming from the vents was not as cold as it has been. I had this problem a few years ago and called a tech and he replaced a circuit board (not exactly sure which one...but I remember it was to the tune of over $300.00) which fixed the problem. Now three years later it seems the problem has resurfaced.
The outside unit "hums" while the inside blower runs. The temp at the thermostat when moved to different temperatures cuts the inside blower on and off as usual, but the outside unit continues to "hum". If I turn the inside breaker to the outside unit off and back on again, the outside unit starts in about a minute and works for a little while until the desired temperature is reached inside the home and the outside unit turns off (as it always has done). When the AC turns back on again, the outside unit does not turn on (inside blower works fine) and we repeat the same cycle...I can flip the inside breaker to the AC and that seems to do perform some type of "reset".
There is also a box (I think it is a service disconnect switch)(Interstate Electric Model# 80315--It is like a pull out flip switch that is labeled OFF and ON...flip one way to ON and pull out flip 180 degrees and insert to OFF) that the outside unit is connected to. I have also removed this "flip switch" after resetting the breaker and the outside unit has turned on.
I have inspected the contactor and its arm moves freely; however, the contacts appear blackened.
The Unit is a Nordyne and was installed back in 2003. Any information and assistance will be greatly appreciated.
Thanks again in advance,
