Question about GE Zoneline Deluxe Series Cooling & Electric Heat Unit AZ25E07D3B

1 Answer

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.

Re: ge ptac

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.


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


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


Replace the Board in the control box



This my friend will definetly solve your problem.    These problems i see everyday with these same units.

Check the air filter and coils are cleaned. If it's o.k, then it is due to short of gas. Find out the leak and arrest it, then do vacum and gas charging.

GE Zoneline PTAC Leaking

Hi Julie,
Is this a newly installed unit? The problem sounds like the sleeve is improperly installed. The sleeve should slope approximately 1/4 inch downward from inside to outside. This way the water will run to the back of the pan where it will be picked up by the slinger fan, or drain to the outside. Most likely this is the cause, not the styrofoam pan. If you need further info, you can contact me at greg.mcnary(at) (replace (at) with @) and I can get you detailed installation instructions.

How to best run this thing

Hi Laurelrobin,
When the unit is on "low fan", it is fan only, and is recirculating room air. If the damper is open, it can also bring in outside air. If the space is not occupied for extended periods, it's OK to turn the unit "OFF", as long as you have a newer unit with Heat Sentinel, and the Heat Sentinel is turned on. Heat Sentinel will not let the room temp get above 85F, as long as the unit is OFF. Also, in most cases it's best to keep the damper closed. You can check your owner's manual for more info on the Heat Sentinel and other auxiliary functions. I also have an article on the temperature limiting functions of the GE Zoneline.

Feel free to contact me at greg.mcnary(at) if you need further info.

Zoneline PTAC short circuit

Most likely you will need to either replace transformer or there may be a low voltage flat type "car fuse" usually 3 amp or 5 amp for just such an occasion. Good luck!
