Yes, the electric heat tip tells about them..


If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes 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 different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

How to set the dryer for the most heat


Your dryer will have heat settings on it. Often there are just 2 , a warm dry cycle and a hot dry cycle and you select the one you require. Other machines will have more temperature setting options.
So just check the controls on the front of the dryer and you will see how to operate the temperature settings. The most simple machines will have the timer and the heat settings on the one control knob.

I have a frigidaire gallery series dryer that will run on low heat setting just fine but when I set it on medium or higher it shuts off after a minute or so. ..I replaced the thermistor but it didn't help....


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.

ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

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.

Electric dryer getting way too hot

3-5 ACCESS TO THE BLOWER WHEEL OR THERMOSTATS

To get to the blower wheel, remove the back of the dryer.

The blower wheel is under the bottom of the lint screen duct to your left, as you look at the back of the dryer.

The operating thermostats are at the blower wheel outlet.

In electric models, the hi-temperature cutout thermostat is mounted to the heat riser.

3-6 TEMPERATURE CONTROLS AND HI-TEMP SAFETIES

These clothes dryer machines use operating thermostats to control the temperature inside the drum, and hi-limit thermostats to prevent overheating of the dryer drum.. Many machines also have extra temperature controls, such as bias thermostats and heaters, hi-temperature cutoffs, and thermal fuses.

Bias thermostats are just like regular operating thermostats, except that they are mounted inside a bias heater. When the bias heater is energized, it generates a small amount of heat, which causes the operating thermostat to open sooner, keeping the dryer drum cooler inside. Thus a bias heater allows a single operating thermostat to act like both a hi-temp and a lo-temp operating thermostat.

A thermal fuse is found on the blower outlet, right next to the operating thermostat(s.) This fuse will blow when too high a temperature is sensed at the outlet; usually when one of the operating thermostats has failed. If it blows, the motor may not start, or you may get no heat (no voltage to the burner.)

A thermal cut-off is mounted on the clothes dryer heater box. It is a back-up for the hi-limit thermostat. Whenever you replace it, you should replace the hi-limit thermostat, too. A high-temperature condition causes it to open, an overheated grounded heat element may also cause it to open.

I have a Whirlpool Commercial Quality Electric dryer Model LER3548PQ0. It heats some but doesn't seem to be hot enough. Does this unit have more than one heating element


Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.

Dryer gets hot and turns off


Hello there:
A lot of the times the problem lies with in the Cycling thermostat that is going out Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly.and can make the dryer stop working after it is working for a given amount of time If so, you need to replace it.
Next is the The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.
It overheats and shuts down due to a bad thermostate Usually when an electric dryer overheats it's because of a defective cycling thermostat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above). It seems to run forever If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system. Normally, this is what happens during an automatic cycle: The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

My Kenmore dryer seems to have a mind of it's own on heating. Sometimes it heats very hot, sometimes little heat at all. It does not seem to matter what setting it is on, low, med, or high. Nor does it...


when was the last time you cleaned it out,try running it with the vent line removed,you need to clean out the duct that the lint filter slides into,vac out the inside of dryer where the motor is,if you have a shop vac put it on blow and blow off the motor and clean out the vent line and the outside vent,if the vent line is long i use a leaf blower to clean out the vent line,also is it gas or electric?next time send model number?if it's gas you could have bad gas coils,when they heat up they fail,clothes are warm at end of cycle.run the dryer for 15 to 30 minutes and check to see if the flame is still lighting if not bad gas coils.hope this helps

Dryer runs hot on low heat setting


What kind of dryer do you have? Some dryers use a bimetal or snap-disc thermostat with a heating element under it to control temperature. the heating element is used for the low heat setting to make it turn off early since it will sense a temperature higher that what is actually there. If the heating element is bad then the thermosat will only operate at the high temperature. You should look at replacing that element.
