Hi, I’m Patricia Bleckman with KE2 Therm Solutions. In this video I’m going to cover how to quickly and easily troubleshoot a temperature sensor.

Although our temperature sensors are extremely robust, from time to time our technical support team is asked for the best way to determine if the temperature sensor is working correctly.

The answer is to submerge the sensor in an ice bath. This is the quickest, easiest, way to determine if the sensor is reading correctly.

To create the ice bath, mix 80 percent ice with 20 percent water in a container. Place the sensors you would like to validate into the ice bath. The temperature should be reading 32 degrees.

Another method that is commonly used is to compare the reading of KE2 Therm’s sensor to a third party thermometer.

The issue we commonly see here is that many of these devices are not calibrated or even worse do not use a sensor that is appropriate for the temperatures required for refrigeration applications.

Another thing to consider is that since sensors rarely fail, it is also important to make sure the sensor does not have damage to its wire and that it has a good connection to the controller’s terminal block.
