Dryer heats intermittently cycles off heat then will cycle back to heat when it cools down. Drum and fan continue to work. Clothes seem to just air dry. Takes forever.
Re: Dryer heats intermittently clcles off heat then
The intermittent nature rules out the thermal fuse (which is either burned out or not).
Take off the panel so you can watch the burner. If the ignitor comes on for a minute (you will see it glow), but then turns off with no gas igniting, the problem is probably the gas-valve solenoids.
If the ignitor heats up only once in a while (like after the dryer has been off for a while), but the gas consistently is released and the fire lights whenever the ignitor heats up, the problem is the thermistor (thermostat in the blower). The second thing is actually the easiest to fix, and cheapest. You my find that simply cleaning the thermistor probe will fix it. For my kenmore, the part has been updated from the original to limit the degree to which it gets fouled up with gunk. I can give you links to parts and/or instructions if you like.

Please make sure that you've removed all of the lint from your dryer prior to every cycle. Next, try to see if the varying the load size effects whether your clothes are heated or not.
If all else fails, please schedule an inspection by Whirlpool by calling 1 (866) 698-2538. Thank you.
if u can run it on delicate or fluff cycle with cool air more than likely its ur cycling thermostat or the hi limit thermostat going defective test it with a meter for ohms..
1. On gas and electric dryers that have an "Auto Dry" cycle, the cycling thermostat is often used to advance the timer as well regulate the drum temperature. Essentially, thermostat will alternately turn on the heat source or the timer motor when the temperature has been satisfied. To check this thermostat, you will have to check for power to the timer motor with a multi-meter, during a cycle. This is a live voltage test and caution should be used.
2. Some dryers will use a cool down thermostat to tumble the clothes without heat, at the end of the dry cycle. Power is routed through this thermostat to the drive motor to keep it running until the drum temperature has dropped to a specific temperature. If this thermostat fails it can cause the drum to turn indefinitely or until the door is opened. You can check the thermostat for continuity with a multi-meter. This test should only be made with the power removed from the dryer.
Lastly check the moister sensor for OHMS according to ur schematic as it must show a certain amount of ohms as per ur unit. When unit has been on short while
DRYER OVERHEATING:
Heating Element
A defective heating element can make a dryer too hot or not heat at all. . If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.
Other Causes and Conditions Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.
Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.
HI LIMIT THERMOSTAT DEFECTIVE? SHOULD SHOW OHMS AT ROOM TEMPERATURE
Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.
Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer. https://www.youtube.com/watch?v=3m5NZvY9V5Q GOD IS still GOOD !!!! SO MY ADIVE IS FREE
I would check the cycling thermostat and hi limit thermostat as they regulate heat. the cooling cycle should come on at end of cycle as the thermostat detects the dryness of the clothes. also may want to check the moister sensor inside the drum usually on the door, they look like 2 aluminum strips.
Your drum may be out of round. The drum belt on the outside of the drum may be rubbing against the cabinet. When the cabinet heats up, the side walls of the cabinet may be bowing inward, thus making contact with the belt on the drum. This would explain why it is intermittant. When the heater turns off, the cabinet cools and the sides bow back out.
I have a ref. thermometer, round metal type I got a Wal-Mart that I check the dryer temp at the discharge. I bent the metal bottom so I can lodge it in the discharge pipe, turn the dryer on and watch the temp. Normally on high heat it will go up to 140-150 and cool down to 120-125 then cycle back on.
