Why Is My Heat Pump Not Switching to Heating Mode?

With a couple months of cooler weather still ahead, being able to heat your home is essential. So if your heat pump isn’t switching to heating mode, your initial instinct may be to panic. But don’t worry too much. If you are in need of heat pump repair services in Olympia, WA we are here to help.  In the meantime, read below to discover common reasons for this issue.

Reversing Valve

This valve is essential to your heat pump. The reversing valve is what allows your heat pump to switch from cooling to heating mode. If the valve is stuck in a certain position, then you won’t be able to switch modes. The reason for immobility can often be traced to the solenoid, which can be replaced. Other times, the reason the valve is stuck is due to a refrigerant leak. If this is the case then your reversing valve will need to be replaced.

Refrigerant Leak

Regardless of whether your system is in cooling or heating mode, your heat pump needs an exact amount of refrigerant to operate correctly. If there is a refrigerant leak somewhere in your system, you may notice lukewarm air blowing into your living space rather than the heat you prefer. Refrigerant leaks are typically hard to detect. If you suspect this, it’s best to call a technician to inspect and repair your system if needed.

Thermostat Troubles

Your thermostat is the heart of your heating system. Thermostats cue heat pumps to change modes, but they can malfunction just like any other component. Sometimes the components inside the thermostat can become dusty, which affects its operation. Or perhaps the wires connecting it to your system have become frayed and corroded. Another reason for a faulty thermostat is an issue with programming.
