Having problems with your Air Conditioners ?

Fredrick heat pump p-tac window unit

\015 When outdoor tempeture is cold, and A/C is being used,defrost thermostat locking out compressor. Only way to reset is to pull unit out of case, take thermostat in hand and warm, after doing so compressor will come back on, but will not run long in cold weather. Is there any thing that I can do to resolve the problem. I have several units doing the same thing. I have checked all the electrical, and all parts seem to be check out fine. But still the defrost thermostat is locking out compressor. \015\012\015\012 Thank You,\015\012 Greg\015

I don't believe that's a defrost T.stat but a outside air lockout. it's there to save unit from slugging refrigerant. if they don't have a low ambient kit. most are adjustable.

I have a Rheem A/C Heat Pump split with gas backup. The gas unit is mounted in the air flow directly before the A/C HP coil. Should the gas unit be wired as stage two heat, or is it OK to wire it as just aux/EM heat? There is no other heating unit. What is the difference between stage two and aux? Please note that the aux gas heat cannot come on if the heat pump is running or it may hurt the heat pump due to the gas heat units location.


Stage 2 is okay as long as there is a fossil-fuel kit accessory wired in the field control wiring. EM heat would only allow gas furnace operation if the thermostat is set for EMER HT mode.......this is not ideal and not recommended. Dual-Fuel applic ... Air Conditioners

We installed a Daikin heat pump in June 1996 Model FVY453CBV1 in Dunedin NZ. It stopped and a repairer said the compressor unit is rusted through & recommeneded a new heat pump. I am looking at whether there are alternative solutions and want to check whether it is economical to replace the compressors, or alternatively whether a new external unit can be purchased. Do heat pumps have a life in years? Is it risky to marry a new external unit to the existing internal unit? I appreciate your help

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

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 a Ge AZ28E12DABM1 Heat pump Window Unit Front Fan Motor Will not Come on


... GE Air Conditioners

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.

I have a GE ptac zoneline 4000 that wont heat on resistance but will on heat pump. It will heat when the unit has been off and the temp is below 40 f. after it has been on for 5 minutes the heat goes off but the heat pump keeps going. Checked all sensors and they all read about the same 6 k. If i put ice on the room air sensor the resistance heat comes on so I changed the sensor but, the same problem continues.

Friedrich YM18 230 volt heat pump. The unit has heated and cooled well for about 5 years. Just started heating mode recently and the unit no longer heats. Fan runs OK. Was able to get the heat strip to run for a few minutes (smelled the dust accumulated over the summer burning off). Now, no heating whatsoever. When in the "Money Saver" mode, nothing happens. Fan will not come on and unit will not heat. With "Money Saver" mode off, the fan runs.

I have a 10 SEER heat pump about 16 years old, yesterday I notice that the outside unit was making a loud click noise in the heating mode. It's very close to the defrost electrical curcuit board. The unit still was putting out heat inside but decided to turn off the unit and use the emerg. heating. What could that loud clicking sound be? concern, Gilbert


Depending on make and model sounds like a check valve clicking. It can sound like it is coming from that area. You say your unit is 16 years old. Honeywell did servey on unit 10 years and older and found out they loose 25% effeicency after 10 years. ... Air Conditioners
