Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

Hello,

Hello,
Your have one of two problem causing the gas to not come on on your dryer.
1) the flame sensor is bad...if the igniter comes on and stays on and doesn't go off...usually within 1 minute the flame sensor isn't working as its supposed to
2) the coils on the gas valve could be the problem...if the igniter does indeed go off within 1 minutes and as soon as the igniter goes off if their is no flame the coils on the gas valve is what would need to be replaced
here is what each part looks like

FLAME SENSOR


GAS VALVE COILS


I hope i have been able to help you fix your dryer,

Try shutting the unit off at the breaker box for your home. Leave it off 1 to 3 minutes then turn it back on. This will restart the board. If this doesn't fix it then the moisture sensor may be bad.

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...

to me it sounds like your venting going out side,if it doesn;t get a clear flow it will come on and off the thermastate inside sencing to much heat.try unpluging the vent then try it if it stays on then you know your answer

Clean the vent all the way to the outside.
The dryer will take 4-5 loads to reset the filter sensor.

Mahe sure the vent is not smashed behind the dryer.

Check the ignitor underneath the drum. (You have to open the panel to see it) It should glow shortly after the dryer starts, then the flame starts and the ignitor shuts off. If the ignitor does not glow then it or the thermostat is bad. If the ignitor is glowing but the gas does not light then the flame sensor may have to be replaced. If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

If everything above is OK then the thermostat or the auto sensor is not working correctly.

You dry by sensor???

Clean your sensor. The machine thinks the clothes are dry because the sensor is covered with who knows what???

Check your owner manual for the proper way to clean the sensor.

I hope this works for you

Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow. If it glows for several seconds (up to 15 seconds) and then goes out, then the problem is probably the solenoids (coils). If the ignitor glows and stays on, then the problem is usually the flame sensor.
