A dryer usually overheats because of a kink or blockage in the duct work, blockage in the outside wall cap, or because of a defective cycling thermostat. The cycling thermostat tells the dryer when to heat and not to heat. Clean any lint from the inner and outer ductwork. You can also remove the vent from the back of the dryer for a load or two to determine if the clothes dry faster or not. If this doesn't fix it, go ahead and replace the cycling thermostat. Make sure to use the appropriate setting to dry the clothes.

    The dryer pulls in air from the front, so any piles of clothes
    may
    be blocking air flow. Vents should be rigid or flexible metal. Plastic
    venting collapses easily, collects water, and collects lint. If your
    dryer can't get rid of any excess heat or moisture, the heat will build
    up in the dryer drum, and becomes a fire hazard.

    You should empty the lint trap either before or after every
    load you
    dry. The warm, dry air needs to be able to flow through the wet clothes
    to be the most effective. You also cut the risk of dryer fires by
    keeping the lint trap clean. You can wash the lint trap in soap and
    water and scrub it with a nylon brush periodically to wash the filmy
    residue build-up from it.

Dryer starts and about 5 minutes later stops and lights start flashing


DRYER OVERHEATING: Heating Element
A defective heating element can make a dryer too hot. 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.

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.

Dryer runs then shuts down wont start up for an hour:
Bad motor windings

Dryer will run about 10 minutes then shut off. Try to turn it back on and it just will buzz


Either a motor with bad windings,. or an over heating problem?

Dryer starts (heat on) after 5-8 minutes heating cycle stops and only cool air run through.


your heating element need to be cleaned.......

1. pull the unit out from the wall
2. Remove the screws holding on the larger rear panel.
3. Using a vacume cleaner extension, remove as much debris as possible from all accessible components.
4. Clean out the dryer vent and the connection to the wall, making sure that air can pass easily.

THAT SHOULD DO YA. If the heat continues to cut off, you are dealing with a faulty heating element in which case you will be best off to purchase a new dryer. (replacing a heating element is typically the beginning of a failing unit)

GOOD LUCK AND PLS RATE THIS POST!!!

Dryer heats to proper drying temperature and then temperature is not maintained and drops off causing long drying time when on timed drying...GE Medallion 850 - bottom heat sensor was cleaned.


you didn't mention if dryer was gas or electric. gas dryer could have bad valve coils which will work for a short time and then fail, cool off and then work again and fail, causing intermittant heat.

Dryer runs but won't heat


As the clothes gently toss about inside the drum, a temperature control thermostatic disk regulates the heat. It is set for 160f for cotton and it mounts on the blower housing. As air is drawn into the drum and out the backside of the dryer the heat is regulated by this control. It sends 120 volts to the gas assembly. Right next to it is a fuse. The duct fuse is set to blow at 250f. Should that control fail to open and allow for heat to build to abnormally high temps. Note: the fuse will kill the heat source only on most dryer, the dryer will however continue to run. Lint and vent blockage can restrict the airflow and make the heat inside build to dangerous levels.The control thermostat powers up the heat for a minute then shuts down for a few minutes, then repeats this all throughout the drying process, the gas does not stay on! That would burn the clothes. If both of those items check ok and the dryer vent and lint has been cleaned, I next take a look at the gas assembly. I check the flame sensor first. If the flame sensor is open the ignitor will not glow. If that turns out to be good I next check the ignitor itself for continuity. If it turns out to be good I replace the coils. Those coils cannot be checked because they do not act up until energised. Sometimes the coils will work, get hot and fail, cool down and work again. I have some repair photos: HERE

Gas dryer not maintaining heat. 70 Series Kenmore/Whirlpool 76722


Fuse is ok . Problem is the soils on the burner valve . If the dryer heats when started , the electricity goes thru the coils to open the valve . Once the coils get warm , 1 will open (short) until it cools back down . The coils can be replaced just by removing the front panel . Only 2 screws hold the coils in place . No turning off gas , dissasembling dryer .

The dryer runs but does not heat. Thoroughly cleaned.


The duct fuse must have continuity in order for power to get to the gas assembly even though she may run she won't heat if the fuse is blown. 53481c0.jpg
If that is good and you have power to the gas assembly nothing will happen if the flame sensor is dead. If the sensor is good then the next thing to check is the ignitor. MORE

Kenmore gas dryer starts to heat but does not maintain the heat. It cools down after a few minutes.


Something simple for you to try is: remove the duct from the dryer,run a cycle,IF the unit works fine, you will need to have your vent system cleaned to the outside. If you still have troubles, you will need to place a service call to have the unit diagnosed
