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.
