Intertherm heating Unit comes on but the blower doesnt work, and it just clicks. I just started having this problem, do you think that when I vaccumed all the dust out I might have disconnected a wire? It was working just fine before then. It even worked afterwards, I noticed it the next day that it wasnt run properly.

I replaced my outside unit with a 3 ton goodman heat pump unit. My old unit was a 3 ton bryant and the compressor burned up in it. I left the old unit under the house since it seemed to be in good condition. the pump worked fine on ac to start off. But then you had to switch it in heat and back to ac for it to work. So the tech replaced the expansion value and put filters in both lines. I still have to switch it back to heat to get the ac to work. The tech told me that i would have to repla

I have an intertherm rpbmb030k combo a/c and heat. Had frion put in the unit over the summer and a new digital thermostat. Unit has worked great until we needed heat. Unit works great on aux. heat but keeps switching to to defrost mode when standard heat is on.

Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode.

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

We have a lot of Fujitsu a/cs at work and the remote controls get swapped around. One remote doesnt work with an a/c. The same model remote from another room will work so it is not the a/c unit. Are the remote controls paired with the a/c unit? Do I have to do something to pair it to this a/c? Pressing the reset button on the remote control doesnt fix the problem.

We have a Weatherking Heater/AC unit the heater works and the AC worked last summer when we tried the furnace this winter no heat found out it was the 24 volt transformer replaced it and heat worked fine went to try the AC this summer and when we switched the T-stat to AC it burned out the Transformer Again. Do you think we have a short in the wireing to the AC unit


I think you have a definite short and it's in the 24 volt circuit. The only problem is - 'finding a low voltage short' is not the easiest thing in the world to do - so - I would guess you'd need a Service Tech.\015\012\015\012good luck! ... Air Conditioners

I have 2 kickboard heaters in the baseboards under the cupboards in the kitchen (Smith SS7's). They are run off the hot water central heating circuit.

Both units have stopped working - when one stopped the other worked intermittently for a few weeks but now this does not come on either. I have bled both units and if I keep doing this then eventually hot water reaches both but the flo

Because the outdoor unit works in cooling, it sounds as though the contactor and other components outside are working correctly. The problem sounds as though it might be somewhere in your thermostat. Has the thermostat been replaced recently? If so, ... Goodman CKL60AR60 Air Conditioner
