Having problems with your Air Conditioners ?

Ge ptac zoneline AZ52H07DABM1 cannot find any literature on this unit. Fan speed is constant low speed (regardless of setting) Guest complaints on this room are piling up, and I need some literature to properly t-shoot this unit. I did see a reversing valve, so it must be a heat pump model, but the compressor will not run in that mode. Outdoor air temp is 55 degrees. Can you steer me in the right direction? BIG THANX IN ADVANCE. Tom in Okemos, Mi.

Hello Tom ,   I'm sure i can help you with this.... I work on these units everyday. unfortuneately im not there to put my hands on it but i will explain as clearly as possible.    The most common problem I tend to find with these units is that the control board  and indoor fan motor tends to go bad in these quite often.  If you put the unit in A/C MODE  and/or Fan mode and set it to high if it will not speed up from low , then your problem could be in a couple different places.   1st.  The bearings in the fan motor could be wearing down ,  2nd  The Control board could be bad  in that its not telling the fan motor to speed up.

And when you tell me that the compressor doesnt run in that mode at any given time..... which the electric heat and heat pump itself works together so that when the load is really tough  that the heat pump doesnt over work and in general saves life on your compressor.

Solution is this.

\015\012\015\012

Take your indoor fan motor off and and drill out the rivits  and it pulls apart easy, and replace the bearings and grease them.

\015\012\015\012

 

\015\012\015\012

ALIGNMENT OF THE FAN IS A MUST.   doesnt cost much at all the fix this. Just a little time and bearings

\015\012\015\012

 

\015\012\015\012

Replace the Board in the control box

Hi the outdoor unit turns on ( fan runs) the indoor unit does open, no heat or cold air blowing. In just fan mode the unit works fine etc speed setting ok. Its a sharp split type air model # ae-a244j outdoor,ay-a244j indoor unit what would be the problem, theres only two parts in the outside unit behind the side plate where the wires info is,small black box three wires and a round unit with wires. I hope this is help full cheers andrew


My gut says that this is evidence of a bad control board(circuit board). As usual, double check that your batteries are good in the thermostat. I have seen some weird things happen when the batteries are low. This one may be a job for your local con ... Sharp Air Conditioners

Hi, I have a wall mount midea split a/c model- MSG-36HR that will only heat. when put in cool mode it only blow's room temp air and the outdoor unit won't run. On heat mode it works normally. I have cycled power a couple of times, changed modes on the remote numerous times and just in case, changed the batteries in the remote. The unit is about 3 yrs old. Do you have any pointers. Cheers Tom


Most heat pumps are 'fail-safe to heat'. That is: the normal position of the valve which reverses the function is in the position which provides heat. The reversing valve must be powered to switch to the cooling position.Although the ... Midea Air Conditioners

Lg Neo plasma inverter split model s18ahn isn't heating or cooling properly. When in heating mode air con will go into defrost/preheat mode for 5 minutes and then air con will blow out air for 5 seconds and then go back into defrost/preheat mode. When in cooling mode indoor fan will pump out air but will not get cold. In both heating and cooling modes the outdoor unit will not start up and the outdoor fan will not spin. I have just replaced the main pcb board and that hasnt made a difference. Bo

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.

Split system air conditioner works in all modes except heating, outdoor unit is running but indoor isnt.


At certain outdoor conditions (low temperature) there may be a build up frost on the outdoor heat exchanger. This gradual build up frost reduces the performance of the air conditioner. The microprocessor detects this frost build up and will automatic ... LG Air Conditioners

I have a rheem electric furnace with 2 speed fan, seems like the fan runs full bore when its on, even when i just cycle the blower control to ''on'' and its supposed to run at reduced speed. I have to experience with central heating and air, was wondering if it would be the circuit card with the dip switches. Unit was installed in 2003 with a heat pump.


If it is a variable speed blower most likely the dip switch settings. Check the installation manual to see how to slow it down. ... Air Conditioners

In heat mode thermostat set for 68 and room temp on thermostat reads 68, but unit contines to run. The air coming through vents is cool air. Unit never shuts off, runs constantly. This is the case when outside temp is 30 degrees or 45 degrees.


Could be under sized unit or fan relay on unit. ... Goodman PHKJ024-1 Air Conditioner

I recently had a new outdoor unit installed on my central heat and air conditioning sytem. I have had the installer out 3 times and the system still does not operate correctly. Sometimes when it cycles (every other time or every third time) the unit does not blow cold air. Sometimes the unit comes on not blowing cold air and the compressor fan is running but not the compressor. Sometimes after 15 minutes of this the compressor will come on. What is the problem.


It sounds like the compressor needs starting components installed on it. All a/c units have a run capacitor for the compressor and another one for the condenser fan motor. These motors use these capacitors all the time when the motor is running. H ... Air Conditioners

I have a 18000btu LG mini split heat pump installed about 1 year ago in vacation home. In heat mode the unit cycles on and off when room temp is within 2-3 degrees of set point. Cycle on time varies between 35 to 60 seconds (sometimes more). The off time is 2-3 minutes. During this time, I check inside temp with accurate digital themometer mounted at the air intake of the unit and the temp does not change, assume because unit does not run long enough. When I put temp set point more than 3 d

I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan

I have a Heat Controller EKTH15-150J PTAC. Of lat,e toward the end of winter here in southern Missour,i the unit while in heat mode has been randomly blowing cold air. Often you can shut off the unit and let it sit for awhile and when you turn it back on it will come up heating again. A couple of years ago I replaced the control board that had been killed by a lightning induced power surge with a RSKP006 control board kit. It has run fine since, until the last few months. Sometimes I can pu

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 sunbeam 12000 btu window unit air conditioner. I can't seem to change the fan speed when it is in cool mode. When I put it on fan only it blows extremely cold air and i can change the fan speed. When i press the power button it stops blowing but it sounds like the motor is still running and I must unplug it to get it to stop.


Sounds like the switch is wired wrong.\015\012When you put the switch on fan only the compressor should not run at all, therefore their shouldn't be any cold air.\015\012Check the switch to see if it's wired right. ... GE Profile ASM10AA Air Conditioner

I have an Edgestar Portable Air Conditioner AP12000HS. The Air Conditioner works wonderful, however I can't get it to heat, I put the Mode Button on red which is supossed to put the heater on, it will run for a few minutes and then shut off and it does not take the chill out of the room I have the unit in, is there some kind if thermostat internally which can be set? The way it runs now does not do me any good as a heater.


The unit has a built in thermostat in the front control panel, this is what maintains the set temperature, it is very likely that this control is defective, all the controls for the unit are contained in the CCU (central control unit) ... Air Conditioners
