Recently when I went to turn on the central air I noticed that the air coming out of the unit was not cold. It was right before I went to bed so I didn't check the compressor outside to see if it was running. today I had some time, and I fired up the AC and checked outside, and noticed that the fan was not running.
I checked the breaker and flipped and a couple of times, this did not turn it on.
I checked the high voltage and low voltage wires at the compressor and I was getting a reading on the high voltage, but my volt detector could not pick up a hot wire on the low voltage line.
No obvious obstructions to the fan or motor, no wire inside the unit seemed worn or torn, and was properly connected.
I can hear a faint hum at the compressor as if a motor is trying to run but it is not actually running.
This is a very old unit, it's a GE and I am wondering if it came with the house when it was built in the late 70's.
Anyone have any idea what could be the cause or perhaps a start in the right direction? I'm not sure I can afford a new unit right now..and I can only imagine how much repairs may cost to an old unit like this.
