refrigerator repair Las Vegas – defrost thermostat test

When it comes to troubleshooting refrigerator problems, there are some things you can do yourself, and others that should probably be left to the professionals, like Best Refrigerator Repair technicians.  One area that you can check for yourself is the defrost thermostat.  Here we’ll look at how you can test whether your refrigerator’s defrost thermostat is working properly.

Since you can’t tell if a defrost thermostat has failed simply by looking at it you’ll need to perform a continuity test. A continuity test will determine if a continuous electrical path is present in the thermostat.

If the thermostat has continuity it should be functioning properly no continuity means the electrical path is broken and the thermostat has failed. If you’re appliance’s thermostat has a closing temperature of thirty degrees fahrenheit or above you can easily test the part for continuity by using a multimeter. There are variety of meters to choose from for this demonstration we will use both analog and digital models.

When using a digital model, again rotate the dial to the lowest setting for ohms of resistance (or resistance with tone if your meter has this option), before you begin. Make sure the thermostat you’re testing has been removed or isolated from the appliance since the thermostat is activated by a change in temperature.

Place it in a glass of ice water for one or two minutes. Now use a probe to touch one of the thermostat’s terminals and the second probe to touch the other terminal. If the meter reading shows zero ohms of resistance the thermostat has continuity.  If the needle does not move or the digital display does not change significantly, there is no continuity which means the thermostat has failed and will need to be replaced.
