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

What is the make and model?

hi 1st check heater for breaks then go for stats

there is a cycling thermostat in line with the high limit thermostat and timer circuit,on timed dry its disabled and the timer will run no matter what,on any sensor dry setting it uses the heat of the element to heat this cycling thermostat to move the timer as the clothes get drier as the heating element heats the timer doesn't move,when the heater cycles off from the high limit thermostat then timer moves again,you need to find out if its a bad heating element,thermal fuse or possibly even a circuit breaker in the homes electrical panel tripped out on one of the 2 phases that gives you the 240 volts required to operate the dryer element,the breaker may not show its tripped,so shut it off and back on and try this first

Sounds like a bad timer. Your dryer is a Whirlpool product.so a replacement timer should be easy to locate. If the timer is advancing but the dryer won't stop, the problem could be the control unit. Run another load of clothes and take notice of the timer's position. If it doesn't run out, then it's very likely the timer. The video below shows step by step instructions for replacing the timer unit.

Hi,

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.
