Diagnosing the stuck HVAC reversing valve

Is there a pin in the transmissio n or transfer case that can come loose to make it not shift into reverse


There's no pin as such. An automatic gearbox does have solenoids for operating valves.
A valve can become stuck.

Reverse gear is first gear - when you select reverse a 'cog' moves onto first gear to reverse the direction of the gearbox output shaft - giving you reverse.

It may well be a stuck valve. Try selecting reverse a few times after the car has been run and the fluid is hot. A stuck valve (in the transmission) may free itself

Cool mode well reverse ob valve to heat


On a Rheem the reversing valve engages on heat. On a Goodman (and most others) the Reversing valve engages on cool. You will want the thermostat to engage the reversing valve on the orange. There may be a switch in the thermostat that allows you to chose either O or B. Select O. If you have a choice of wire on the thermostat of either O or B than choose O. Also check and make sure the thermostat wire goes to the outside unit. Also make sure you have a thermostat that is comparable with your heat pump.

Is there a way to free up a stuck reversing valve


Before you get ahead of yourself, check to ensure that the reversing valve is the problem. You may have an electrical problem that is preventing the reversing valve from moving either by the reversing valve being constantly energized or not energized at all.

But if your reversing valve is sticking...

Since most reversing valve failures are due to a low refrigerant charge and/or lack of proper maintenance, there is not much you can do outside of getting the system serviced and have the refrigerant levels checked.

If the reversing valve has failed, you should take into consideration the age and condition of your current system. It may be more economical to replace the system in that situation.

I have a goodman heat pump and i suspect a bad reversing valve


Sounds like reversing valve is stuck or metering device or check valve is stuck open. If it is a scroll compressor on 3 phase you may need to reverse 2 motor leads. try tapping reversing valve with rubber mallet when running. This may have done in last compressor by sending discharge gas to suction side.

Reversing valve issues.


You will need to replace the reversing valve. You cannot replace the coil with a remote sensing bulb on this unit. Usually you know when reversing valves get stuck when you are having low side problems with heat working properly

Reversing valve not switching over to air on heat pump. compressor will come on for about 10 minutes, then shut off. Hot air comes out vent.


Look for any refrigerant leaks - no or low refrigerant can cause problems in both modes. The unit may be going off on low suction.

-OR-

The unit may be stuck in the heating mode.

Make sure the system is calling for the correct mode (cooling or heating) - some systems are auto, but if you can, select cooling since that is the requested mode. Check for power at the reversing valve inside the condensing unit. If power exists, then the reversing valve is stuck. It could also be the reversing valve solenoid coil, so make sure that isn't bad. There should be a strong magnetic field at the solenoid coil.

If you can hear the reversing valve clicking (moving), check the T-stat and make sure it will switch modes. Also check the reversing valve relay (those can be located in either the indoor unit or condensing unit).

My intertherm heat pump has freon but will not heat is it posible that the reversing valve is stuck in the middle and will not let it heat if so where can i get a new one.


Verify power to the reversing valve relay.
Some reversing valves energize in HEAT some in COOL.
Tap the reversing valve with a hammer handle while it is on. If it is stuck, it may come unstuck.

HEATER DOES NOT TURN ON BUT AC WORKS.


- If no voltage output at the thermostat for the supply of heater/reversing valve, then replacement of thermostat is needed (but check the thermostat setting).
- If the voltage output at the thermostat for the supply of heater/reversing valve is present, then then check for heater/reversing valve fuse or overheat protection, and check for defective heater/reversing valve
