To check if a thermostat is working correctly, first turn it up to a desired temperature above the current room temperature. Then wait to see if the thermostat kicks on and runs the HVAC system. If the HVAC system starts up, wait until the room temperature reaches the desired temperature and make sure it stops running.
If it continues to run after the desired temperature has been reached, the thermostat isn’t working correctly. If the thermostat doesn’t run at all, it could be malfunctioning or the breaker could be tripped.
If the breaker is tripped, reset it and try testing the thermostat again. If the thermostat still doesn’t run, it may need to be replaced. Additionally, check the wires and connections of the thermostat and make sure it is mounted in an area that is not receiving direct sunlight or high temperatures from other heated objects like lamps or TVs.
How do you test a heating thermostat?
Testing a heating thermostat begins with making sure power is properly supply to the unit, which may be done with a voltage tester or multimeter. Make sure the thermostat is set to the correct heating cycle and the right temperature.
If these parameters are correct, the next step is to disconnect the wires from the thermostat base and attach them to the component being tested, such as an electric heating element. Turn on the component and note the temperature readings on the thermostat during the heating cycle.
The thermostat should accurately reflect an increase in temperature and turn off the heat when the correct temperature is reached. If all of the components of the thermostat are functioning correctly, the thermostat should pass the test.
If the thermostat does not detect the increase in temperature or does not turn off the heat at the correct temperature, it may indicate a problem with the thermostat or one of the component parts. The thermostat should be either replaced or the component parts should be replaced.

How do I test my thermostat with a multimeter?
Testing your thermostat with a multimeter is a relatively straightforward task. Before beginning, make sure to turn off all power to the device and remove the cover. You’ll then need to locate the terminals and note which ones have power and which ones need power.
Once this is done, use the multimeter to test each terminal. Simply set the dial to measure volts and connect the multimeter probes to the terminals you wish to check. You should expect to see approximately 24 volts in the terminals that have power connected.
Terminals that need power should show no measurable voltage. If the meter shows abnormal readings or no reading at all, the thermostat may need to be replaced.
If the terminals you tested all show the expected readings, turn on the power to the thermostat and set the thermostat to its highest setting. Check the thermostat terminals with the multimeter again.
If the thermostat is working, you should now measure high voltage at the terminals that have power connected. If the readings still appear low or off, the thermostat will need to be replaced.
