I have a Whirlpool Dryer LER7646EQO. I need to know how to diagnose the automatic dry-miser feature.
the way this works is you set the timer to say more dry,you start it and the heat comes on,when the dryer reaches temp the heat shuts down and the timer starts to advance,it will move a little until the heat comes on and it stops advancing,dryer heats up and it does this until the clothes are dry,when on timed dry there's a clock motor on the timer and the timer uses the clock motor to count down.this is the difference,now does the timer advance at all,if not you could have a bad timer or the heater element is touching metal and grounding,you can start the dryer on air fluff and see if it gets hot, also try running it on timed dry and see if it advances to off or does it stop at a certain point and doesn't go to off,or if you have a volt meter,pull off the vent line,remove the back panel,remove the wires going to the heating element,set the meter to say 20k ohms,touch the leads together and you should see anything but 1,now touch one lead to one side of the element and the other lead to the metal case that covers the element,if you get any reading other than 1 the element is grounding to the metal case,check both sides like this,also while you have the back open,did you remove the metal duct that the lint filter slides down into,if not do it but you said you changed a gasket there so i'm sure you did this,if you look to the right of the duct you'll see the thermal fuse and the cycling thermostat remove them and check them out,if you had that much lint in there they probably are covered with lint also,the cycling thermostat tells the dryer when to cycle when it gets hot and cool.if the heater isn't grounded most likely you have a bad timer,you can run it on timed dry and see if it gets stuck on a certain spot and doesn't fully advance to offhope this helps you out
