GE Room Heat/Cool unit will not heat with heat pump
GE model AJHS10DCBM1 room heat/cool unit heats with heat pump for 3 minutes then shifts to back up heaters. Unit cools fine but this year has developed problem with heat pump. Heat pump only works for 3 minutes and then the system switches to the backup electric heaters. This problem occurrs at all values of outside air temp. Manual states backup heaters should come on at 25F. The 3 minute time is consistent as if it was being controlled by a timer. Suspect control board but would like a second opinion before I invest in new board.

air conditioners are in effect heat pumps
that is they pump the hot air in the room via a gas to the outside area
when that outside are is still inside the room then that hot air is just recirculated
so if you want to heat your room the system is reversed so that you need the hot air outside pumped back into the room
the hot air is provided by the condenser which is now the evaporator in the room as the roles have been reversed so you will have to put the unit in a door way or use the ducting hoses to go out a window
After I have been reading up on your unit it appears that the thermostat is not operating correctly. I found this real basic information on installation for your unit. This link I am giving is pretty basic instal schematics. But seems to be something about your thermostat needs to be dialed in or is not working properly.
The smallest retail AC unit will cool down a 110 sqft room if...
1. It is installed in a way as to dump heat outside... 2. There is actually cool air coming out of the AC (it is working)... 3. The windows and doors are tightly closed... 4. There are no major drafty leak issues (i.e. hole in a wall)... 5. You're not adding substantial heat energy into the room (such as having 10 sweaty fat men eating food while watching Super Bowl on a 56" LCD TV)... 6. The room has at least minimum insulation (the walls are not just plywood)... Seriously, if HEAT is leaving the room by way of the AC, the room temperature HAS to decrease, unless HEAT is being added back into the room in some way. This is basically the 1st law of thermodynamics.
Air conditioning real definition is not giving cool but removing heat from the room. In same way for heating, it's not heating, removing cool from the room. When your indoor coil, air filter and blower wheel are full of dust, you won't get even 30% of cool or heat depend on your selection. Simple solution for your problem is clean indoor unit completely. Check all sensor is working well. In heat mode keep temp minimum +3 degree than room temp. thanks and helpful.
1. Turn the power off or unplug the Room Air Heat/Cool unit. 2.Follow the power cord of the unit. This will normally terminate at the fuse terminal/power reset button., where you can replace the fuse. 3. After the fuse/power reset button terminal the wire go to a thermostat normally located at the air output section at the front portion before it goes to the motor and heating element, while the other wire may connect direct from the fuse terminal to the motor or heating element. This is just the basic electrical set up, it can be modi- fied. Hope this will guide you in locating the fuse and the thermostat. fied
OK I will be looking over the manual. Now that squeal sounds like the squirrel cage fan scraping the housing around it. Those units are so tight fit they can be twisted one way or tightened a little to much they scrape. I love them for there silence win they work right but hate them because my hand are too big to move things around inside them. Stay in touch I will be looking around while multi-tasking today- I'll be here!
Yes this will recycle the room and can be cover outside if it is not a heat pump and will use elec heat strips to heat. As long as it is tilled toward the back the water will run out the back without a drain kit there should also be a drain hole in the bottom.
