Problem with GE PTAC-Model# AZ28E09DABM2 - Why won't condenser kick on when switching to AC from Fan. AC was working fine until today...Fan is still working...Pulled the unit out and could feel the h


Hummm. A bit difficult to solve this problem. Seems like the condenser outside is not working, I mean the fan of the condenser. Looks like you have a wall A/C and a wall A/C always have condensers outside the house and near the A/C. Have you checked if the fan is spinning? I don't think the compressor is at fault but check it anyway. You should be able to hear the compressor running either in the wall unit or in the outside condenser housing. The only heat you should feel is from the condenser itself. If you blows warm air, that means the fan is working, if not that means the fan is not working. But don't be confused with the fan not working because in winter time sometimes the fan is not working and some times it does. As I said, it's a difficult problem to solve but at least start with checking the situation with the fan in the condenser.

I'm not getting heat from my unit..


the compressor is controled seperately from the fan, this is done with the thermostat, try turning the thermostat on then of or untill you hear the "click" sound from the thermostat. If the compressor is still not turning on this may be more than you can fix if your not familiar with electrical hvac troubleshoting... more than lilkely the thermostat may be bad, or your compressors starting components are failing...if the compressor is comming on when the unit is turned on you could have a freon leak causing no heat. hope this may help some there is just too much to write on the causes this will give you a start though!!

Will not switch to cool mode. heat and fan work fine


hi,
regarding on switch mode theres a common line between heating and cooling although fan is always connect on them.,also with the thermostat,the sequence on this when you switch to cooling and your connection is on heater,the contactor will shift to compressor source,so if there is no cooling, the contactor supplying the compressor is not functioning when you switch on cool mode.try to tighten screw on compressor relay maybe only loose.on control panel,or check continuity of compressor if the compressor still good,check also the freon charge using clamp ammeter,this should be done by ac technician.have a nice day
rate me up,thank's

LG PTAC acting strange in heat mode


I believe the problem in lies in the dual stage heat mode setup on the thermostat, but the unit going into defrost does make the unit act kinda strange. Even more so than other types of equipment. I would suggest hiring a licensed HVAC service technician if the problem cannot be resolved by yourself.

2 problems.. AC Comp cuts out. And Fan will not stop.


Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!

Ptac fan keeps blowing


Try setting the fan control to "AUTO" this will cause it to cut out with the compressor.
