Kenmore 90 series

There's thermal fuse on the blower that blows when the cycling thermostat malfunctions or the lint/vent duct are blocked. This thermal fuse is wired in series with the dryer motor and if it blows, power to the motor is terminated causing the dryer not to start and no dryer function works. Check to make sure that the lint filter is always clean and the vents are clear. Click on the link below for the detailed troubleshooting of the dryer, particularly the thermal fuse, when it doesn't start.

Troubleshooting Not Starting Whirlpool and Kenmore Dryers with Lint Filter on Top

OF COURSE SOMETHING BURNT INSIDE THE SYSTEM. YOUR MOTOR MIGHT BE BURNT. 90 SERIES, YOU MUST HAVE THE LINT FILTER ON TOP CORRECT? TAKE FILTER OUT, UNSCREWS THE TWO SCREWS, PULL TOP PANEL TOWARDS YOU AND LIFT UP. DISCONNECT LID SWITCH CONNECTOR, UNSCREW TWO SCREWS HOLDING FRONT PANEL ON, REMOVE FRONT PANEL, TAKE DRUM OUT AND CHECK THE UNIT. GOOD LUCK

Check the lint caught in the exhaust vents. If it is clear replace the spark ignitor if no click is hear upon starting up

that's normal,obviously you haven't cleaned out your dryer and vent line,nobody ever tells the customer when you buy your dryer that it should be cleaned out at least once a year so you don't have a fire more so if it's a gas dryer with an open flame inside the dryer,you gotta vac out the inside where the motor is,clean out the duct that the lint filter slides into and blow out the vent line,i use a leaf blower to clean out the vent line,take it off the back of the dryer,stick the leaf blower in the line if it's a long run if it runs through the wall and to the outside flapper and blow all the **** out of it,also if you have a shop vac put it on blow and blow off the motor,you won't believe how much lint comes off the motor even though it looks clean,so vac out the inside of dryer,clean out the lint filter duct and blow out the vent line

The door switch or actuator is broken. A common problem. On most Kenmore dryers this is replace by lifting the top. Since you haven't given the whole model number I will discuss raising the top on the most common model.

If your model has a lint filter at the top the slide show below should show you how to raise the top.

Kenmore Dryer

Disconnect power to unit. Lift the cover from the lint filter or if yours is the one with a filter and cover together, remove the whole filter. You will see 2 screws under the cover/filter, remove them. Now, you will need a putty knife or a thin shafted straight screw driver to remove the top panel. Push the putty knife or screw driver to "pop" the front top clips. The top panel will hinge back towards the wall and can be left there. Just inside the top of the front panel, you will see 2 screws, remove them. You will see the wires for the door switch on the right side. *** the top of the front panel toward you to gain access to the switch for replacement.

Reverse process for reassembly. Good Luck

easy, get some high temp adhesive before opening up.

then if lint screen on top, remove screws under cover, pull top forward and lift. it hinges in rear. remove 2 screws on front holding front panel to cabinet sides. disco door sw and lift front panel up to remove. undo belt from motor , note setup with spring roller.

if lint screen in door, remove contrl console, screws under end caps(pop off frame end caps from top). remove screws at rear of top holding it to rear panel. and slide forward. to remove. remove lower kick panel (use putty knife, hidden clips in seam), remove screws holding air duct to blower housing, disco wires to moisture bars at connector. remove screws holding front panel to cabinet, then at top and remove panel remove springs if necessary. pull tensioner away from belt and remove belt.

lift drum up and out. note gasket flange orientation and pull off. clean and sand off old as well as possible and apply glue to drum as you apply new gasket, it will be tight at end.

Your motor is very likely overheating and needs replacement. A simple test is the motor will be so hot you cannot even touch it. Hope this helps!

By overheating I presume you mean the high temperature fuse is tripping.
The two most common causes are poor air flow and a bad themostat. If there's a good flow of air coming out of the exhaust vent then it's likely the thermostat. Expect to pay $20-30 plus labor for a new one.

possible motor overheat ..if unit has a lot of lint or has had vent problems now or in past lint may have accumilated around motor and caused it to overheat and shut off.. probably to late to save motor

the motor overload can caouse that problem in that case new motor is needed if the dryer turn right back on after it turns off the even heat control board in panel bad if it humms are no noise after turn off and you have to let cool down the motor is the problem
