The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the ignitor and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot ignitor and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly.

Hi and welcome to FixYa. I am Kelly.

Your power for the burner assy goes on a series circuit from the timer to the high-limit thermostat to the operating thermostat to the thermal fuse to the gas burner assy, thru the motor centrifugal switch to the door switch. EACH of these must be functioning for the burner to light.

This manual will help with some of the how to do it as far as component access, removal and replacement of parts.

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.

Fails to turn off, and now no heat.


Runs and never stops:
In all probability this may well be the timer motor has quit,and thus the timer needs replacing right? Maybe, but you need to first check to see if your dryer has a moisture sensing system, If the sensor board contacts get corroded or goes caput, then the dryer wont know when to advance and shut off in newer models!

The heating element have got old and brittle over time and finally gave up the ghost. But it is not always the element. It could be one of the safety Hi-limits have blown. All parts of the dryer will have continuity if its working properly. Test for continuity by using a meter set on Ohms,or use a poor man's meter. You can make your own poor man's meter by using an ordinary flashlight . Break the circuit in the flashlight and add a couple of wires to it so that you can make the light come on in the flashlight, that's right hot wire that flashlight. When the bulb lights up you have a circuit! You now have a poor man's meter. The next step is to check each little gizmo on the dryer that the wires attach to. All the limits attached to the side of the heat element, the door switch (when door is closed) etc.should have continuity (closed circuit)(the light should come on in the poor man's meter) If you come across an thing near the blower housing with 2 wires attached to it, that is a thermal limit, a safety or a control thermostat (So as not to get a false circuit you need to remove one of the wires to each thing you check) Look for lint buildup or blocked vent going out the house. If everything is good and you have paid the electric bill, then the timer could be bad.

Whirlpool Gas Dryer LGR7646JQ1 Auto Setting Does Not work


I am thinking the timer has gone bad, They tend to work in some spots, and not others , when they fail. If you can put the dryer in Auto mode, then nudge the timer until you hear the burner light, see if it continues from there. If it does, chances are pretty good it's the timer.
