Why Friedrich Air conditioner starts to shift but does not complete reversal?
- J
  John Ramirez Jr.Aug 21, 2025
  If your Friedrich air conditioner starts to shift but doesn't complete the reversal, it could be due to: * **Not enough pressure differential:** Check the unit for correct operating pressures and charge. Raise the head pressure. If it still doesn't shift, use a valve with a smaller port. * **Body damage:** Replace the valve. * **Insufficient compressor pumping volume:** Raise the head pressure and operate the solenoid. If it doesn't shift, use a valve with smaller ports.
