Having problems with your Air Conditioners ?



Answers :

If you switch the fan switch at the thermostat (I assume it has a fan - on - auto - switch), does the indoor fan come on at all? If not you could have a fuse on the indoor board out (on newer systems), or a bad transformer.
Now what caused this?
If you don't have an idea electrical surge, a wire touching someplace (possibly when you changed the thermostat out??) that should not have, and / or possible a bad contactor could have caused it.
An amp meeter on 1 line of the transformer when powered back up showing less than 2 amps is acceptable but over 2 amps and definitely over 4 and your fuse will pop again (or transformer. Just test it and be ready to unplug if it shows this condition).
I assume you have a clamp on amp meter or can borrow one for this test.

If this helped you understand and correct your problem plaese rate me as high as you can. If you need more please post back with what you have found and I'll post back to you. Thnaks for using fix ya and good luck.

My fridgedaire window unit A/C and heat won't come on. I had replaced an outside light fixture a couple of weeks ago and had turned off the circuit breaker that affected this unit too. Now the unit won't come on AT ALL. I've unplugged the unit, then flipped breaker off then on again. Then plugged back in and hit "Reset" Button on the plug, then waited at least 3 min. as instructed, but still no power. The light on the plug doesn't even come on when I hit the test button. Could it be a faulty cor

I have a Sanyo Split System the indoor unit is a KHS0921 and the outdoor unit is a CH0921. When i first turn the indoor unit ON the fan will run for a few minutes and then go off. The outdoor unit never comes ON when there is a cll for cooling. The only way to get the fan to come ON again is to turn the breaker OFF and then back ON.
