Carrier Apu Ac Not Working. Heres the problem apu turns on no problem a few minutes if it running alone I start the heater n not more then 20min if it running the apu seems to wanna die so the heater turns off automatically and when the engine settles up the heater turns on again. My carrier apu starts fine on low ac it will stay running but the display goes to check apu engine. If there is a problem with the main control board it might not send voltage to the compressor.

The dual shaft fan motor or circulation fan motor might be defective. The front AC is working good we just charged it up under the engine hood. I have a carrier pc6000. The main control board provides voltage to all of the components of the air conditioner. On one side the fan blade draws in outside air over the condensing coil to dissipate the heat.
