LG Dryer Heater Sensor

I have diagnosed a non-re-settable fuse as blown in the heating element of my LG DLE5977W dryer. A question that has come up is...did the fuse blow because the temp sensor at the end of the line went bad? The fuse is about $13.00 and the sensor is about $30.00. Is there a known temp at which the sensor should open? If it's known I could heat it in the oven and test it for function. I am a little leery of heating it with a propane torch for testing.

Thanks for the help,
Mark

Almost always the reason your fuse went out is the vent is clogged to outside. Repaired washers, dryers for almost 15 years and the main reason for dryer failure is a clogged vent.

Thanks for the response. I cleaned all of the piping, inside the dryer and out to the outside. There wasn't much lint in there but what was there is gone now. New fuse is installed and it is running. Next will be to discover if the thermostat at the end has burnt closed, causing the fuse to blow. The parts house suggested that as a possible culprit.

If the cycling thermostat was burned/shorted on....... the limit sensor you just replaced will burn open quickly.

The cycling stats usually fail open and don't close. I can't remember ever seeing one short.
It doesn't take much lint to block good airflow.
