The ignitor can glow and still be defective.
Take a volt meter and check for power at the gas valve while calling for heat.
If you have voltage, replace the coils again.
No voltage, replace the ignitor and flame sensor.

My Maytag gas dryer, Model No, LDG7500AAW will run but not heat. The igniter glows red, but the gas will not flow. What might be wrong?


Replace the 2 burner coils ,if the igniter keeps cycling trying to start the flame. If it doesn't replace the flame sensor mounted on the side of the burner tube.

Dryer won't light. Igniter glows, then turns off,


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...

Frigidaire crown gas dryer runs fine but after about 10 minutes it turns itself off and i cant turn it back on for about an hour


From the description you give the most likely cause of this problem are bad gas coils or a bad gas valve.

You say you see the flames for 10 minutes before it stops heating but you don't mention if the igniter is continuing to glow. One thing we need to know is if the igniter continues to cycle on and off when the dryer stops heating.

There is a small square plug on the front panel you can remove to try and visually check if the igniter is glowing.

The problem won't be the thermal fuse or one of the thermostats. Once the fuse is open the dryer won't heat but it won't start to heat after 20 minutes.

After the dryer runs ten minutes and stops heating then check if the igniter is still cycling on and off. This is important because if the igniter is working then the thermostats and igniter are okay.

When the igniter glows at some point you might hear a click and the igniter would stop glowing. The click is from the flame sensor and after the click and the voltage is removed from the igniter at the same instant the voltage is applied to the gas coils and you should get a flame.

You might hear a hum, buzz or vibration from the coils when this happens. If the coils seem to react to the voltage but there is no flame then most likely the gas valve is bad. If the coils don't do anything then most likely the coils are the problem. The gas valve and gas coils can work for 10-15 minutes and then heat up and stop working till everything cools down.

One other thing I must tell you about the gas coils. Here is a link to the gas coils you will need. These are the new style that will last quite a bit longer the the older one. The coils are like the spark plugs in your car. The will need replacing in time due to wear. Below is a video to walk you thru the repair process.

No heat


This information is Courtesy of expert heatman101

If your gas dryer is not working because it is not heating then you need to check this out. Today?s gas dryers often do not use the simple thermocouple with a pilot to prove the flame anymore. They use a much more complicated method of lighting the burner and proving the flame.

The use of electric igniters has become the standard for many dryers today. The thermostat calls for heat, power is supplied to the igniter, then after a certain amperage draw on the igniter, the gas valve is energizes to open and allow gas to flow starting the flame. As long as the amperage draw on the igniter is high enough then the gas valve stays open till the thermostat is satisfied.

Sometimes the igniter will crack and no current will go through and the igniter will not even heat up or glow. Sometimes the igniter will wear to the point where it will still heat up and glow, but the current draw will not be high enough to allow the gas valve to open. This creates a confusing situation where you look into the dryer and see the glow from the igniter, but get no heat because the burner never lights up. If this is the case then you will need to replace the igniter even though it seems to be okay. The only way to know for sure is to know what the current draw requirements are for that gas valve and to have an amp meter to check the current draw.

I have an Amana Dryer Model # LGD20AW and when the dryer is first turned on the glow plug will heat up and ignite the gas but as the dry cycle continues the glow plug will heat up but no flame will ignite...


The glow coil or glow bar heats up and a sensor on the side reacts to the heat and then sends a signal to a gas valve.(solenoid valve) When the gas doesn't ignite when the coil is glowing... here are some reasons. 1. The sensor on the side of the burner assembly isn't working or sending power to the valve. 2. The valve is getting power but not opening. 3. The ignitor is not glowing hot enough to activate the flame sensor. Usually it is the sensor or the igniter not the valve.

If electric then the thermostat or the heating element has failed.
If gas: First thing to check is 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.

No Heat on a whirlpool dryer. 14 years old.drum turns,timer moves,getting gas to valve,tapped solenoids-no change.burner not lighting. thanks for any info


if ignitor not coming on could be flame sensor mounted on side of burner housing or ignitor ..if ignitor glowing but burner no lighting replace both solenoids bad connections interally on solenoids..also if ignitor not glowing possible small white thermal fuse open.. sensor and fuse can be jumped across to confirm ..

No heat


You may have a weak igniter. Just because the igniter glows, does not mean it is working properly. The glow bar type igniters are supposed to draw a certain amount of current in order for the gas valve to open. If the current potential is never met, the gas valve will not open. This is a safety feature used to prevent gas flow without ignition. The current readings for the igniters are as follows: Round style glow bar: 2.7 to 3.2 amps Square style glow bar: 3.2 to 3.7 amps If it is reading less than the required amperage, replace it. This may just solve your problem. Let me know if this helps you.
