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. Switched out the defrost board on the unit to no avail and an a/c guy checked to ensure the new thermostat was wired correctly.
Hi, if the unit had a leak in it, was the leak located and repaired? Did he check the pressures in the unit now? If it switches to the aux mode ( Heat Strips ) is normally caused when your primary unit, compressor and freon are low on charge. I would ... Intertherm P3RA-060K Air Conditioner
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. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode. The thermostats seem to be functional because relays can be heard clearly when changing temperature se

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.
You have a bad board or bad switch. I would say board. You can have service tech check this out. There is only so far you can go without knowledge of Controls ad electricity. Russ ... Air Conditioners

10yr Vulcan Central Heating unit. Had tech come out and said main fan unit was faulty. I replaced myself and still not working. I discovered the O/Temp manual switch had cut off power. When I reset the switch the unit comes on and all works except for my fan which then the unit heats up and cuts off.

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. The model number is AR-RY3

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. The fan in each unit is supposed to click on to blow hot air from the heat exchanger when the temperature falls. 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

Goodman AC Unit with Heat Pump - Works great cooling when switched to heat the outside unit does not come on - inside comes on and uses emergency heat? What can I check? I first checked the contactor and it looks fine, the inside thermostat had low battery voltage...replaced batteries but still not working? Any help? Thanks
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

I purchased a AMCOR portable air conditioner Model ALD12000E/EH on Mar 30 2009. This unit does not heat or cool only the fan works. When the unit was first received the heater worked fine although there was a strong odor associated with the heat cycle. I am not sure if this unit is worth the cost of repair.

I have an NewAir 12000H Portable Air conditioner with a heat pump. The problem is that the heat pump no longer seams to be working. The desired temperature is 79 degrees. the unit never gets above 75 degree. when it actually gets that high it because my heat from the house has turned on. once the heat goes off then the unit goes down to 72 degrees and stays there until my heat comes back on. whats wrong with the unit? is there anything that i can do?
It sounds like the actual control module, the "brain", of this heater / air conditioner has failed and can't sense when to kick on the heat any longer. Have you tried just unplugging the unit for a good 5 minutes minimum and seeing if it will help " ... NewAir Air Conditioners
Heating and air condition unit will not kick on when i try to turn the heat on in the morning. we have tried the auto fan and the on fan for both ac and heat...will only work for the ac. the breaker switch at the breaker box is the only solution we have found to get the unit to fire up and to start the heat for the unit...my brother has checked the wiring at the thermostate..mercury type..found no burned out wires...he changed the filter on the system...tried to clean all the contact points on

I have a Carrier Air HVAC unit, It is not heating the house. THe fan works, the AC works, but when I turn the thermostat to heat it will not come on. I am thinking maybe a thermocoupler. The model number is 585HJ036060. Where can I find a service manual for this unit?

My Ruud heat pump/AC blower does not come on for cooling or heating. Both units work as does the outside fan unit. Blower is only thing that does not work. I noticed my KWH usage was more than double in a 24-hour period as of today. too! What could be wrong?
The blower/fan motor may be shot. The fan ON/OFF circuit switch, may be locked up or has totally failed. The only way to test it, is with a circuit tester to see if the fan is in fact getting power.Hope this helps you troubleshoot the pro ... Air Conditioners
I have a Siemens rdh10rf thermostat which is working erratically. The hot water works but heating is not always coming on when it should.

It then cuts out and a red light comes on. Can you tell me how I can fix this?
