This advice is for problems associated with GAS DRYERS that RUN, but DO NOT HEAT. Ensure your dryer ducting is clear and not clogged, first. ALL dryers require proper air flow in order to dry efficiently. If you do not 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 no “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 not 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 solenoid, 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 enough 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 enough 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.

Gas dryer throws reset after a few minutes


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.

Gas dryer


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.

Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

Gas dryer dosn't heat properly


The problem is the dryer coils are failing. They tend to fail as they heat up. They are inexpensive and easy to replace. Here is a link that should help http://appliancehelponline.com/gdryertroublevideo.html

This is probally the coils. They tend to fail as the dryer heats. There is a video at www.appliancehelponline.com/servicemanual.html that will walk you thru the troubleshooting. It's a different model but the testing of the parts will be the same.

It runs but no there is no hot air


the first thing you want to make sure is that the igniter is working, remove the orfice on the front of the dryer, an start the dryer cycle, it should glow if it doesn't then you have a bad igniter, if the igniter glows an you have no heat (at all) you want to check the thermalfuse onthe dryer, check for continuity with a voltage tester it it beeps means is ok , if it doesn't pass current replace it,
if you get partial heat only then it would look into the coils, the 2 coils are inside on the front of the unit. coils are replace for the most when your dryer takes a longer cycle meaning it takes longer to dry or finishes an clothing still damp.

good luck.

Dryer gets hot but wont dry clothes


Do you know if the dryer vent is free of obstructions?Check outside where the dryer vents outside ,and see if the air is weak or flowing freely.If it is not clogged the air should be pretty strong from the vent outside.If it has blockage it will definitly take longer to dry your clothes.

No hot air


If you have a pilot light (small flame) you can try to re-light it by turning the knob on the gas valve to the pilot position and pushing the knob down while lighting the pilot, you may have to hold the knob down for up to 30 seconds before releasing it. The pilot should stay lit and then turn the knob to the on position. If the pilot will not stay lit or the main burner will not light it could be the gas valve or the temperature sensor.
