Kenmore 90 series Hi My dryer gets very hot in a short period of time and then turns off. Not on long enough to dry any clothes. The drum and the outside of the dryer is hot. Can you help? Thanks

If its getting hot and cycling and your drum is turning than the problem is a clogged or kinked vent hose or maybe a bird nest in the exterior defuser.

Your Sensor that senses the clothes are wet or dry is shorted out. The dryer works likes this so the dryer heaters dont stay on while the clothes are dry. When the sensor senses the clothes are damp or wet, the heater stays on, when they start drying the sensor senses it and starts to turn down the heaters

Check your dryer venting for obstruction.  Take the vent hose off and run the machine,  If it works with the venting disconnected, It is between your wall and the outside of the house.  If it still has the same problem it is somewhere in the exhaust.  If the dryer can't circulate air, nothing will dry.

could be your vent plugged and causing the thermal fuse to open up and go bad.

Hi, It's an over heating motor that's cousing the thermal switch to trip, on the motor.

Motor retails for $150.
Labor for putting it in is $90.

It might just be worth replacing it.
Sorry for the bad news :(

Best of luck.

The problem is with the gas assembly coils. They get hot and quit. Then later on they cool off and will work a little bit. Making it an agrevating intermittant problem. These are only 20 bucks and easy to replace:

Hi, if you get no glow on the ignitor and you have voltage its the little white two terminal fuse on the exhaust side that has no continuity on the series 80 it has 2 blue wires, these complete the circuit for both gas valves and the ignitor. If you have an ohm meter it you will find it rite away. Hope this helps.

dryer will not start

Poor drying problems with dryers generally are attributed to clogged ducting. You have probably heard this before, but the first (and least expensive) fix for any dryer with long dry times is to check the air movement. As well know, dryers require good air flow to ensure proper drying. Now, when you said the air movement is strong, were you checking it at the air vent exhaust outside, or were you checking on the back of the dryer? An easy way to tell if there's a clog in the ducting, or a clog in the dryer is to run one load with the dryer vent disconnected from the back of the machine. Only run one load like this. Not a good idea to blow hot moist air into an enclosed area of your home over a period of time because it can cause mildew problems. If the dryer blows freely and your clothes dry faster, you know you need to check the ducting from where it connects to the wall to where it ends at the exhaust vent. Often it is not enough to just clean the lint trap and the outside vent. You need to check what's in between them as well. Mice and birds are notorious for building nests in dryer vents and clogging them up. Now...if the dryer is blowing poorly at the exhaust port on the back of the dryer, you will need to remove the door kick panel under the door and remove the vent duct housing to get to the blower fan. Make sure you unplug the dryer before attempting this. There are live voltages present even with the dryer turned off. Lint can get trapped in vent housing and restrict the movement of the fan, which, in turn, will cause poor air movement and longer dry times. Last of all, take a temperature reading at the exhaust port on the back of the dryer. A good temperature reading is roughly 140 degrees F. If the temperature is too low, you may have an operating thermostat or high limit thermostat malfunctioning. Check your vent ducting, first and let me know if you need further assistance. I hope this helps you.

A couple of possibilities to check. First, is the lint trap empty? If so, then the symptoms point to hot air bypassing the drum. Look for broken or misaligned plastic ducting inside the dryer itself. Check the exhaust air for moisture, as that is a better indicator than temperature. Don't forget that towels hold an enormous amount of water, & can be extremely long in drying, especially if not spun enough.
