This is the service manual for this system. It might give you an idea on what the problem could be. Page 27 should be your area to start. There are two for the PTAC series. I'm not sure which one will pertain to you.

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. This unit was made about 1994. Help Paul

Hi! I have a problem with an oil heating system! When I turn it on, it heat for 5 mins then stops. I have changed out the circulation pump as I thought that this was the problem.

There is water in the radiators and none are air locked as i have tried them all.
