Question about GE Zoneline AZ55H07D Air Conditioner
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.
If it was me I would cnage the sensor first. Simply because it is way cheaper than the control board and these sensors are fickle as hell to begin with.
