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

The following link will give you some additional advice on how to troubleshoot a dryer:

http://www.fixya.com/support/r385301-thorough_dryer_advice

Read through the link provided, thoroughly. It does cover many common dryer problems and how to diagnose them.

You know at this point that have power to the unit, because the drum light is working. Now...with the door open, does the light go out when you push the door switch in by hand? Is that how you determined the switch to be good? If the light does not go off, the switch may not be working properly and the dryer will not start. Another easy item to check is the thermal FUSE. The fuse is located behind the lower panel under the door. It is a white plastic component mounted to the top of air blower housing right under the drum in the front. There should be two wires going to it. If the thermal fuse is good, it should read a short (or close to zero ohms). These two first items I mention will kill a dryer from starting and are the most common problems to start with. Read through the section "Dryer Does Not Run at All" and let me know if require further assistance. I hope you find this information helpful.

SOURCE: Whirlpool gas dryer Model #WGD5530SQ0 not heating properly

If your dryer heats when you first turn it on and after a few minutes it does'nt. check the ignitor to see if it is glowing. It should glow bright then you will hear a click and the burner will light. If the ignitor glows bright but you hear a click but no flame and if you watch this for several minutes and this process continues of glow then glow goes out no flame, then you have a bad burner coil. There are 2 black solenoids sitting on top of gas valve. One of them is shorting out after it warms up. Replace both solenoids. You can usually get them as a kit from parts store.

Whirlpool dryer does not get hot enough to dry clothes.


Clean/repair the dryer vent. If the airflow is restricted the result is the one you just described.

Good luck,

Dryer runs but will not heat. Replaced fuse and


your cycling thermostat needs changed too. the thermal fuse is your last safety measure that goes, which means your cycling thermostat is not shutting down the heat element once it detects the right temp hot air in the blower housing so it let the heat element glow until either the high-limit sensor shuts the heat down or the thermal fuse blows. Change the cycling thermostat and good luck

Not drying


I know you cleaned the lint vent but your vent hose is clogged or damaged and there is no air exchange thru the dryer Air can only hold 100% humidity. You could dry your clothes for 10 hours but the air in the dryer is saturated with water and can not hold anymore so your clothes wont dry. Check behind your dryer and Ill bet the vent line is damaged. The problem is the air is not getting out of the dryer. Check the flapper at the end of the vent line. With the dryer running go to the end of the vent hose and there will be no air coming thru.
