It can be annoying if the heater that your thermostat controls works and then turns off unexpectedly. 

According to Cadet, the heater won't turn on because it detected abnormal temperatures. Also, the sudden stop is due to the wrong voltage connection.

Another reason why the heater turns off is the thermostat settings. You may observe that the heater is cycling every 15 seconds. If that is the case, you should update the thermostat settings. 

If you have a digital thermostat, here are the solutions suggested by Cadet:

  • For the TH401 model - change the heating cycle from "Std" to "Fan."
  • For the TH106 model - change the factory setting to the ON position

For non-digital thermostats cycling less than 5 minutes, the cause is the wattage inside the room provided with heat. 

Refer to the owner's guide for detailed troubleshooting instructions. If you need further assistance, contact the Cadet technical support team.

Should You Set The Thermostat To Auto Or On?

With the thermostat, you have the option to adjust the fan settings. Whether you keep the fan setting on or auto is a matter of preference. You can use any of the settings depending on your family's needs. Read the distinctions of the settings below.


If you set the thermostat to ON, it runs the fan constantly. Some advantages of this setting include:

  • Distributes air inside the home evenly
  • Better air filtration and flow
  • Less stress on the heater's fan

However, you might spend more on this option. You also need to replace the air filter often, which adds to your expenses. Sadly, the constant heat can make your home colder in the winter.


On the contrary, setting the thermostat AUTO will only work when the HVAC cycle starts. Once the cycle is over, the thermostat automatically turns off.

With the AUTO setting, you can save on energy and air filter replacement costs. Besides the cost savings, you will benefit from superior dehumidification during summer.

The major disadvantage of the setting is the absence of air circulation when it is off. Other downsides of this setting are less air filtration and faster wearing out of the fan. 

Both settings have their pros and cons, so it is up to you which to use for certain times of the day.

In Summary

It is easy to turn off a Cadet digital thermostat. On the touch panel, press both + and - simultaneously. Then, press the M or - buttons four times until the standby icon appears. The icon will blink slowly to signify that the thermostat is off.

There are various Cadet thermostat models, so it is best to refer to the product manual for instructions.
