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!

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

SOURCE: I have a zoneline ptac unit. The water keeps

They used to use a black rubber hose to run from the front to the back of the unit on the very bottom of the unit. You may also look for a styrofoam chute . Make sure the unit is sloped to the rear slightly.

PTAC Blows Cold Air in Heating Mode when it reaches -3F less than the Set Value on the Thermostat - Model: AZ65H15DABW6

It sounds like your PTAC (packaged terminal air conditioner) unit is malfunctioning. When the thermostat is set to heating mode, the PTAC should be blowing warm air, not cold air. There are a few possible causes for this issue:
  1. The PTAC may be low on refrigerant. If the unit is low on refrigerant, it may not be able to properly heat the air.
  2. The PTAC's reversing valve may be stuck in the cooling position. The reversing valve is responsible for switching the flow of refrigerant between heating and cooling mode. If it is stuck in the cooling position, the PTAC will blow cold air even when the thermostat is set to heating mode.
  3. The PTAC's heating element may be malfunctioning. If the heating element is not functioning properly, the PTAC will not be able to heat the air.
I recommend contacting a trained HVAC technician to diagnose and fix the issue with your PTAC. They will be able to determine the cause of the problem and repair it properly.

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)airdistributors.com if you need further info.
