Hello! My LG dryer model #DLE3777W runs but won't heat. I replaced the High Limit Thermostat and the dryer heated for one cycle and then no heat after that. Next, I replaced the thermostat and still no heat. Could it be the thermistor? Looking for recommendations of what to do next.

Thanks so much!

Hi Butch,

Ohm test the thermistor, make sure the dryer is unplugged when ohm testing.

At 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms. at 100 degrees wpi;d be 6.2K ohms, 120 degrees 4.3K ohms. If the thermistor reads outside of the range then it needs replaced.

Here's the thermistor for your model:
6323EL2001B Thermistor Assembly
