Question about Haier Heating & Cooling
Hi, on all heat pumps, the reversing valve will be energized in the cooling mode only. The only units that the coil on the valve is energized in the heating mode is a Rheem and Ruud unit, they will default to cooling if they fail, this is crazy but they do it. You say your reversing valve is energized and stays there. I know you don't have a Rheem. If it is energized at the coil, it must be in the cooling mode. If you want it in the heating mode, and it is not switching the sleeve and ball bearing in the valve, it may be the thermostat, a faulty reversing valve 24 volt coil, or the control board at the outdoor unit it self. I wish I knew what season you are in, if you live where it is hot or where its cold right now? For a temp. fix on this, you can de-energize the valve by removing the panel where the compressor is and unplug the coil to the valve and it will switch back the other way if the valve isn't hung up its self. Very easy to unplug this coil, just grasp the black plug if you are sure it is energized, and pull it off of the 2- terminals to remove power to it. Depending on what mode it is in, I am assuming cooling as it is energized in cooling, you can also go to the circuit board and find the o or b terminal, which ever is being used to switch the valve, and take off the wire. This should kill the power to the coil. To find out which part is causing it not to de-energize, you will have to start at the thermostat after you hook all up like it was, and remove the o/orange wire or b/blue wire to see if it kills this coil. If so, the stat is bad. If not, wire it back up and go to the control board. Kill all power to the a/c. You want to take a look at the back side of this board. It is very tight and will have 4-stand off screws to remove. If you need to remove any wires, write the colors and terminals they come off of so you know where they go. This is very important. You just want to peak in behind it to see if you see any hot or burnt spots anywhere. I have seen this over, and over again. If so, this board is the problem. If you are still getting 24 volts to this coil when you are not in the cooling mode, you still have a faulty stat or control board. These are what sends voltage to the reversing valve coil.I would start with the stat as this is the least expensive of the two parts. If you don't feel you can tackle this, don't feel bad as this is something that you must be or have some training in to troubleshoot it. If this coil is energized, unplug it to kill the power to reverse it, so you can temp. fix this. Please keep me posted on this and please rate me as I know you will be kind. I will be checking in with you to see if you called out any one, and I hope that the reversing valve has not froze up on you.
