Testing Ceramic Thermostat

Know the resistance of the element should be this can be calculated using known values.

Testing ceramic thermostat. R v x v p where v is the voltage powering the element p is. Auto reset type ceramic base. The meter will indicate an open circuit by displaying ol on its liquid crystal display lcd for a good thermostat that has normally open no contacts or it will display zero 0 00 ohms for a good thermostat that has normally closed nc contacts. Method 1 of 2.

Testing a conventional element. I wondered how those little things work. Here is a l. This is a general guide to test any type of heating element for failure using an multimeter to measure the resistance of the element.

If you want a quicker and easier but less accurate test you can use an oven thermometer to test the temperature of the oven and compare that to the digital readout on the oven itself. Connect the multimeter pin ends on point c d as shown in the picture below. It is of single pole single throw structure and works under resistive load. Unless it happens the thermostat has defected.

Some ceramic heaters have a single heat setting or simple low medium and high settings. Before you buy a ceramic heater check out its thermostat. Connect the multimeter pin ends on point a b as shown in the picture below. If your multimeter points near zero then the thermostat is.

If your multimeter points near zero then the thermostat is okay. No electronics no circuitry it just works. To test the thermostat you ll first need to remove it then use a multimeter to test it. Some thermostats give you the option of pre programming your desired temperature.
