i own a LG DLE5977B, that tripped my breakers a few times. it was very hot to the touch (back panel) when it was in normal drying cycle which uses medium heat. this happened a few times, i allowed it to cool each time prior to restarting after resetting the breaker. Now it is working and not getting as hot as it was, i am running it on high and it is not tripping breaker anymore. it feels warm but i dont think it is hot as it should be on high. i have check for blockages and found none. i would expect a thermostat or sensor might be at fault possibly, what parts should i check out?
