Re: Dryer will not heat when using any of the heating...
First check element, then is it isnt broken check safety fuse on element assembly for continuity theres an other termal fuse right of the fan assembly all accesible with the front panel off

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
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.
Make sure a heating cycle is selected. Air and Fluff cycles do not use heat.
Make sure that both phases of 120 volt power are energized (total of 240 volts between the 2 phases).
Most likely the heating element is damaged, which usually means there is no heat at all. A dryer with 2 heating elements will have some heat, but not have enough, when 1 heating element stops working. A dryer with 1 heating element can partially fail and have partial heat, too.
If you have normal heat on Auto cycle, I have seen a few times that these new dryers channel the heat circuit separately through the timer for auto and timed cycle's. This isn't normal but you have a bad timer. But for any other readers this isn't a common problem generally the timer use's the same heat contact for auto and timed cycles, this is the exception.
1
Check the cycle selector control to make sure a heating
cycle has been selected. The selector should be in an "Off" position
when not in use, but it should be turned to a drying cycle when in use.
On some models, make sure you are not accidentally running the dryer on
the "Air" cycle, which does not use heat.
2
Check the gas supply valve to make sure it is open if your dryer is a gas dryer. If it is not open, just lift the valve open.
3
Look at your house's main breaker box to determine whether a
circuit breaker is tripped. The electric dryer runs on 220-240 volts
and has a double breaker. If the breaker for the heating element is
tripped, the drum may tumble the clothes without heat. Turn the dryer's
breakers to off, then back on; test whether the dryer will produce heat.

Consult a technician if troubleshooting does not resolve the problem.
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...
the timer : if you use time dry the timer should always move and complete the cycle. if you use auto dry the timer uses a sensor to tell the timer to move. If your not getting any heat your sensor might not tell the timer to move.
So lets start with the no heat problem. First make sure your Vent is clear or just disconnect the vent and put a pair of womans stocking over the end to keep the dust down, This will ensure you do not have a blocked vent. ((( If you have a blocked vent on a gas dryer the safty sensor will shut off the gas valve and you will only get a little bit of heat))) Now try the dryer for small load, ((( if this solved your problem then you have a cloged vent )))
If this did not solve your problem then the coils on your gas valve in the dryer are probably bad.

Hi, If the dryer heats but will not advance in either time or auto cycles, you need to change the timer. You can test to see if the timer is getting voltage. Remove the top rear panel and locate the two wires going to the timer motor. There should be 120V when the dryer is running in time dry. Please let me know if this helps or if I can assist you further.
stat 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). Drying is too slow
It normally takes about 45 minutes for a dryer to dry a full load. If your dryer is taking more than an hour, check these.
Vent Heating element Internal ductwork Cycling thermostat Vent
Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance.
Heating element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace it.
Internal ductwork
Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum, contact a qualified appliance repair technician.
Cycling thermostat
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.
