Having your heat pump get stuck in heating mode is pretty awful in the middle of summer. It’s possible that you simply forgot to tell it to switch modes. However, it’s also possible that there is a serious problem hindering your heat pump’s operation. Let’s take a look at why heat pumps get stuck in one mode, and what you can do about it.

The Reversing Valve

The reversing valve is the part of the heat pump that makes it possible for the system to offer both heating and cooling functions. It’s a four-way valve that sits in the refrigerant line of the system. Inside the valve is a slide that dictates the direction that refrigerant flows through the system. The slide is controlled by an electromagnet called a solenoid, which moves it back and forth between the two positions. Depending on the direction the refrigerant is flowing, the heat pump will either heat or cool the home.

Reversing Valve Issues

There are two possible problems that can affect your reversing valve. First, the slide may simply become stuck in the valve. The valve will need to be opened, and the slide freed, in order for the heat pump to be restored to proper function. The second possible problem is that your solenoid loses its charge. Without the ability to move the slide, the heat pump will become stuck in one mode. If that happens, the only thing that can really be done is to replace the solenoid. Regardless, you’re going to need a professional to handle this problem for you.
