My dryer is not getting hot enough also. It takes 2 full runs to dry fully. All the vents are cleared, The heating coils are all glowing full when on. I just replaced the moisture sensor & the high temp thermostat. Yes I cleaned out the lint filter area & the blower wheel is turning. The moisture sensor light used to always show high, but now just the low light. Please help.

ANSWER Jamie, you've checked a lot of things, a couple of more things. Check the rubber seal between the blower housing and the inlet duct, make sure there is a tight fit between the two comonents, if it's sucking room air into the blower, it throws the thermostats off. Check and make sure the dryer is level in both directions, When you replaced the moisture sensor, did you clean the surrounding area and make sure the wires were attached properly to the bar and frame, if thats alright then you'll need to repalce the dryness control display. the light "HI" light should illuminate whenever something damp/wet touches the new moisture sensor bar, a new bar and if the wires are OK the problem would be in the display board 33002389 . Thanks and Good Luck
