Being mindful of these precautions will help to ensure that your applications work correctly. Remove the wires from your thermistor with care. What is the relationship between temperature and resistance for the application (curve)? 0 seconds of 3 minutes, 6 secondsVolume 0%. If the dryer is perpetually shut off with the heating element still activated (checking if the towels are dry) without letting the machine run on and letting the heating element PROPERLY cool, it will cause the heating element to eventually sag and break or ground out. Thermistor probes are also ideal for an application that functions in low ranger temperatures. The thermal cutoff is located on the heater assembly and it controls the temperature of the dryer. But when I hook it up the vent (22 feet and very clean) it overheats.. After 20 years of working fine. It monitors the temperature of the dryer, and when that temperature gets too high, it shuts power off to the motor (not to the heating element !!!). Some of the most commonly controlled systems that use thermistors include air conditioning units and refrigerators (to name a few). Both sensor types are available within a similar range of tolerances, and as a result, both can have similarities. Blew the cut out again the same night. When calculating resistance, readings include the resistance coming from lead wires and connectors. As a result of many devices function within a larger unit, high levels of heat are generated. The cycling thermostat monitors the temperature in the heating chamber, and when the temperature rises too high, it cuts power to the heater. Remove the 5/16-inch (8 mm) screws behind the top cover or panel. Over time and use, the thermistor can display incorrect temperature. is a fundamental consideration depending on several factors such as stability, accuracy, temperature range, etc. It blew again this morning after replacing it last night. No heat on air dry only. Usually, the thermostat housing is fastened with two or three 10mm or 12mm bolts. A PT 100 sensor has resistance across the sensing element lower than that of a PT 1000 sensor. It also has the ability to make power factor corrections. Operating a dryer with a bypassed thermal fuse is both unnecessary and unsafe, so a bypass should only be done long enough to troubleshoot a potential problem. If you have a faulty dryer thermostat, the dryer may keep the heat on for too long, causing the dryer to get too hot.
