defrost thermostat problems?

It was a good day, it was a bad day, it was a good day again…

Everything started out great, until I realized there were issues with my refrigerator.  I called a buddy and described the problem and he said it sounded like the defrost thermostat was bad.  All I had to do to make sure was to test it.  And then he excused himself to take another call…

I didn’t necessarily know how to go about testing a defrost thermostat on a refrigerator, but I DID know how to do a search for how to do it.  Fortunately for me, I found an article that told me exactly what I needed to do.  It was suddenly a good day again!

Here’s that article that I found, in case you ever want or need to know how to test your own defrost thermostat on your refrigerator.  This article I found on the site Best Refrigerator Repair Las Vegas (http://refrigeratorrepairlasvegas.org/troubleshoot-refrigerator-defrost-thermostat/)

Troubleshoot a Refrigerator Defrost Thermostat

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 an analog model first rotate the range selection dial to the lowest setting for ohms of resistance then calibrate the meter by pinching the probes together while adjusting the needle to read zero.

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.
