Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.
Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?
Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.
Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.
Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

I would check the vent and be sure it is open and free of lint. That would be the easiest thing to check. If you have the flexible white duct replace it, it is a lint trap.

The solenoid that controls gas flow to the main burner can go bad. Need to test with a voltmeter. If the flame sensor is good then that would be the next logical safety switch.

    My flame sensor has continuity. Where is the solenoid and how do I test it with a voltmeter?

  • Brock Stewart Apr 03, 2015

    Also was wondering should the flame touch the flame sensor or does it just need to detect the heat?

SOURCE: the gas dryer is not getting hot enough to dry

In light of everything you checked, it sounds like you have a bad set of coils on the gas valve. When they go bad, it can take a long time between cycles. Hope this helps!

SOURCE: Maytag Neptune Dryer taking hours to dry a load

Hello Friend, Your solution is simple. It sounds like your dryer is working properly, and your actual problem is a blockage somewhere in your 4 inch exhaust tubing. Check it and make sure it is not clogged up with excessive lint. Also if your tubing is clear you need to check your connection where it travels thru the wall etc. It would be a good idea to find the actual location where it exits to the ouside and check for good airflow. Your dryer is equiped with a safety thermistat and if you are not getting the proper exhaust flow the burner will cut off and restart in the manner that your's is doing. I Hope I have helped you, Tim. And please don't forget to give me your rating for my help.

You might want to replace the thermacouplar. Sometimes when they are going out , all will appear to be alright but as you stated it takes a long time for the flame to come back on. This sounds to me like the thermacouplar is going out.

Maytag dryer runs and tumbles but will not heat up to dry clothes. model # LDG7500AAW, serial # A3351803. it does have flame but will not stay hot. Is this a thermostat problem?


I would suspect a faulty high limit thermostat is causing this problem. It is usually a small round, black device mounted on a small plate and attached to the internal ductwork with two screws. Hope this helped and best wishes.
