Dryer does not ignite (Gas) - no heat?

I have the dryer somewhat apart and have reviewed previous posts. The igniter does not glow and there is no clicking sound.

Verify IGNITER glows the easy method


continuity checks on igniters are seldom accurate. An amperage test is the best solution. Igniters are fairly cheap, just replace if it is suspect. They are a wear item that go bad frequently.

What to do when dryer runs but does not heat up


Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse , coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
Problem -
Gas flame comes on first few times then quits and igniter keeps cycling on and off but never lets the gas go.
Answer ( most common ) -
Replace the coils on the Gas Valve.

Problem -
No flame, no igniter glowing at all,
Answer ( most common ) -
Inspect igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter when dryer should be calling for heat.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Gas dryer heat is intermediate


does the igniter glow white or orange? if it is orange you need to replace it. has to be white hot to ignite. if the igniter is white it could be the coils not opening the gas valve all the time - an intermittent problem.

Maytag Neptune MDG 5500 AWQ heats sporatically


your dryer has a safety feature that it will not run or heat when the door is opened. It is so no gas fumes are exhauseted into your home. Once the safety is engaged, It will not allow the dryer to restart for a short while. It should clear itself after only a few minutes. Hope this helps, good luck.

Model GGW9200LW0 Gas Dryer Unit does not heat, I checked and cleaned the vent line and I also changed the fuse. Still no Heat, any suggestions?


If this is indeed a GAS dryer, the next thing I would do is verify that your igniter is working. If you can see inside the dryer (under the drum where the burner assembly is), there should be an orange glow coming from the igniter after you start it. In simple theory a gas dryer works like this:

1. Press the start button, dryer drum begins to tumble, igniter begins to glow.
2. Once the igniter reaches a specific current level (as determined by the type igniter you have), the gas safety valves open and you have ignition.

Typically, the common fail item is the igniter. They simply wear out with age. I would recommend reviewing the following link to learn a little more:

http://www.fixya.com/support/r401858-replacing_oven_igniter_gas_range

I know the link is for replacing an igniter on a gas range, but the type of igniter and theory of how it operates is essentially the same. It is common to have an igniter STILL glow, but not ignite, because it has become weak and will not draw enough current.

Another problem associated with no ignition are the gas coils on the burner assembly. Your dryer should have two of them. One is the pilot position coil (3 terminals), while the other is called the main coil (2 terminals). If one of these coils is defective, it is recommended that BOTH be replaced.

Searspartsdirect.com has an excellent exploded view illustration of the parts I've discussed here. Just type in your COMPLETE model number and look under the "Burner Assembly" heading. The igniter is listed as item number 4 (part #279311) and the coils are listed as items number 13 (part #694540) and 14 (part #694539).

I hope you find this information helpful. Let me know if you require additional assistance.

Need advice!


Okay...here's what you need to do to check out a gas dryer:

This advice is for problems associated with GAS DRYERS that RUN, but DO NOT HEAT. Ensure your dryer ducting is clear and **t clogged, first. ALL dryers require proper air flow in order to dry efficiently. If you do **t have any obvious vent duct obstructions you can follow these simple steps in identifying WHICH dryer heating circuit component may be defective BEFORE you have to disassemble anything. With the dryer plugged in and the gas supply turned on, follow these steps:

PUSH START – Listen for a “click”. You have to listen carefully to hear it. If ** “click” is heard when you push the start button, this is usually an indication of a bad RADIANT HEAT SENSOR.

PUSH START – “Clicking” sound is present, but dryer still does **t ignite. This is usually an indication of a bad IGNITER.

PUSH START – Dryer ignites, but heating circuits shut off after a short period of time. You attempt to restart, but the dryer makes a “buzzing” sound. This is usually an indication of a bad GAS VALVE SOLENOID.

Now, these initial symptom analyses will give you a rough idea of where to begin troubleshooting. These tips are NOT all inclusive, but suited for the more common problems encountered with dryer ignition problems. In theory the dryer ignition works like this – You push the start button and the igniter begins to glow. This igniter will produce a certain current potential (roughly 2.5 to 3.7 amps, depending on type of igniter) and the gas valve will open. Once the gas valve opens, you have ignition. This is a built in safety feature of the unit that prevents free flowing gas inside your home or garage without ignition. If you suspect a bad gas valve sole**id, the dryer usually has two of them. It is recommended that you replace BOTH of them at the same time. If you suspect the igniter to be bad, open the dryer e**ugh to see the burner assembly. There should be a visible glow from the igniter after you push start. If the igniter does NOT glow, replace it. If the igniter DOES glow, take a current reading to see if it is producing e**ugh current. Here are the two types of igniters are their specifications:

Carborundum – cylindrical in shape (2.5 to 3.0 amps)
Norton – Rectangular in shape (3.2 to 3.7 amps)

I hope this information is helpful. Post back if you have any questions/concerns.

PS From the initial indications you gave, it sounds like you may have a bad igniter.
