Clothes not getting dried

possible blockage in vent if ok bad fan motor or heating element overheating

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?
Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

If it works to begin with and fails afterwards then that can only be them solenoids mounted on the gas assembly. Here is my home video which shows how to check and replace:

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

My whirlpool dryer Model GGW9896KQ2 seems to run ok but it doesn't seem to heat up properly and takes several cycles to dry clothes. I checked the exhaust vent and it seems to be blowing air out ok. Also, it appears the dryer goes to the cool down cycle way to early. In addition, the dryer will sometimes shut off before the time is acutally done. help--I don't want to spend money for a tech or even a new dryer. It's only 8 years old.

Hi, If you have a gas dryer.
The most common problem with a gas and no heat is the ignitor going bad...

Here is a tip that I wrote about that problem...

HI. thanks for the question. the motor seems to be at fault here. did you clean the venting from the dryer to the outside. , did you clean the lint inside the dryer. if not do that, thanks.

hi thanks for the question ther is a thermostat on the air duct at the back of the dryer it has 2 wires at ends and 2 wires in the middle smaller ones this thermostat opens to turn off heat and the small wires on this thermostat when the heats shuts off then power goes to the timer and not before if it shuts off on timed dry timer is ok i would vacuum the dryer make sure all the vent right to the outside is clean as air flow restriction can cause this problem thanks the appliance doc

This is some basic info I could find on your dryer. I will need you Serial Number in order to determine the year it was produced. Please post back with comments and let me know.


Whirlpool Duet GEW9250P 7.0 Cu. Ft. Super Capacity 8 Cycle Front Load Electric Dryer With AccuDry Sensing System. Dry clothes in the time it takes to wash them.
