Troubleshoot Residential Heat Pump Thermostats

Like other types of thermostats, those thermostats that are designed to control your residential heat pump may occasionally encounter certain intermittent technical problems. It is important to know address these problems on your own, since troubleshooting and resolving heat pump thermostat problems can restore comfort to your home without requiring the time and money necessary to consult a repair technician. Does this Spark an idea?


1. Verify the thermostat’s temperature setting. Like other thermostats, heat pump thermostats will only activate a heat pump if the thermostat temperature is significantly above that of the ambient air temperature. Increase the thermostat’s temperature settings to at least 10 degrees Fahrenheit above the air temperature and give the heat pump at least five minutes to kick on.

2. Reset the thermostat. A reset is a simple remedy for many of the most common issues your thermostat may encounter. Depending on the make and model of your heat pump thermostat, there may be a reset button or you may be able to reset the thermostat by turning it off and removing the batteries for five minutes. Alternatively, simply turn the thermostat off for five minutes and turn it back on to test if the thermostat is operating your heat pump properly.

3. Verify that the thermostat has electrical power. If your thermostat is battery operated, replace the batteries. If the thermostat uses outlet electrical power, check the breaker box to see if the thermostat’s breaker is not tripped. Also verify that the heat pump’s emergency cutoff switch is not on, since this will prevent the heat pump’s activating regardless of thermostat settings. If none of the above troubleshooting steps restore the thermostat to proper order, you will need to contact the manufacturer of the thermostat for further assistance.
