Re: dryer runs and heats but shuts off prematurely
It could be the timer or the sensor as well. Before replacing parts, it may just need a cleaning. If you are not familiar with the product then you should call a professional. The dryer is designed to shutoff when it is overheating, which as you stated it heats up nicely, but shuts off.
Lint, the unfortunate result of drying gets on the sensors and other parts and causes them to react prematurely. If you haven't cleaned the unit, it may just need that, if not I would then say start looking at replacing parts. For safety concerns, you should have your dryer cleaned yearly.
Another thing to check is the exaust for kinks or blockage, when this happens it causes heat back into the unit and again shuts it down.
Give those a try and it may just solve your problem.

there is a cycling thermostat in line with the high limit thermostat and timer circuit,on timed dry its disabled and the timer will run no matter what,on any sensor dry setting it uses the heat of the element to heat this cycling thermostat to move the timer as the clothes get drier as the heating element heats the timer doesn't move,when the heater cycles off from the high limit thermostat then timer moves again,you need to find out if its a bad heating element,thermal fuse or possibly even a circuit breaker in the homes electrical panel tripped out on one of the 2 phases that gives you the 240 volts required to operate the dryer element,the breaker may not show its tripped,so shut it off and back on and try this first
It could be a high limit overload, but the cause may be a blocked air vent.
You can remove the dryer vent in the back and see if the problem stops, this will tell you if the vent is blocked or not.
Check the blown fuses and home’s circuit breaker tripped. Dryer use 2 household Fuses or a circuit breakers, If one is blown, the dryer may still operate but not heat. Alternatively, the dryer may heat, but it may not heat up as hot as it should. Replace the Fuses or reset the circuit breaker.
Another common cause of a dryer failing to heat is a faulty Heating Element. You will need to replace it.
Good Luck and have a nice day. Rating the solution is highly appreciated.
Visually inspect the heating element, burner operation, ignitor, thermal fuse.
Make sure there is nothing blocking the front of the dryer. Air flow is key to efficient drying. Make sure the dryer settings are appropriate for the clothes you want to dry. The timer selection, fabric selection, and the temperature selection all play important roles in proper dryer operation.

During the auto-drying cycle, the moisture sensor could be the problem.
If it also shuts off prematurely during the timed cycle, the operating thermostat could be turning the heaters off before the machine reaches operating temperature. Another possibility is that the operating thermostat does not turn off the heaters at all. When the machine heats up, it gets too hot and the high limit thermostat turns the dryer off.
have you checked to be sure you venting is clear leading to the outside of you home. obstructed venting will form your dryer to shut the heat off prematurely with then result in long dry times.
if it is a gass dryer, the the gas valve coils could be goind bad but check the venting first.
Unless I am wrong, I believe the heat in a dryer is either ON or OFF ... there is no "gentle heat" as such. Most dryers achieve 'gentle heat' (or any heat setting, for that matter) by cycling the heat on and off for certain periods of time.
Which is not to say that your dryer is not malfunctioning. If you continue to believe your dryer is not under control, you probably cannot repair it, the on and off cycle being regulated by a variety of delicate sensors.
I suggest if you suspect you are having out of control heat with your machine, it may be time to call the professional to have a look-see.
Your timer may be the cause of both problems. Not cycling and no heat. Whirlpool makes a excellent dryer and is worth repairing. Replace the timer first. If you still have a heat problem most of the other parts are around $30.
lets start simple on this,first check your dryer vent for obstructions(mainly lint build up,)also check the weather flap (where your unit vents to the outside)this should swing open when the unit is in operation.either one of these can cause excessive heat build up in the unit.(this will cause the thermal limit switch to shut the unit down)thus keeping you from setting your clothes on fire.hope this helps,thanx for using fix-ya
