My Heat Pump Stuck

Why is My Heat Pump Stuck in AC Mode?

Monday, November 7th, 2016 at 11:00 am

For heat pump owners, it can be more than a little frustrating if the system refuses to switch modes properly. Blasting cool air is hardly comfortable when the temperature outside is below freezing. If your heat pump is stuck in cooling mode, you're going to need to have a professional fix it for you. While you're waiting for your technician to arrive, though, let's take a look at exactly why the system is acting that way in the first place.

The Reversing Valve

Every heat pump has a part in its refrigerant line called the reversing valve. This is a 4-way valve that has a slide inside it, which moves between two positions in order to direct the flow of refrigerant. The slide is controlled by an electromagnet called a solenoid, which pulls it back and forth between the two positions. Depending on the position the slide is in, the system will be in heating or cooling mode. If a problem develops with the reversing valve, it will cause problems for the heat pump.


There are two issues that can affect the reversing valve. First, the slide can become stuck in the valve. If this happens, the valve will need to be opened and the slide freed. Second, the solenoid can lose its charge. If that happens, the only real option is to replace the solenoid. You're going to need a professional to handle either of these repairs, so make sure you schedule an appointment as soon as you notice this problem.
