Re: Gas burner doesnt ignite somtimes

Time to replace your gas coils. those are the two round things on the gas valve. chances are the dryer ignites when first started but as the dryer heats up the coils fail and as it cools again the coils work again. make sure you replace both coils

My dryer is not heating when I turn it on the glow plug comes on but does not ignite the gas

The most common cause of a no heat problem on a GAS dryer is worn or blown igniter. These appliances are equipped with a burner assembly with electronic igniters. The following link explains a little theory about how these igniters work:

I know the link is for a gas range, but the burner assembly functions are nearly identical, as well as, the type igniters used.

If you are having ignition problems it is probably a simple matter of a weak or bad igniter. The burner assembly will ignite automatically as long as the gas valve, igniter coils and igniter are all functioning properly. It can take up to 90 seconds for the burner to ignite. As the igniter ages, you may experience longer ignition times.
NOTE: Just because the igniter glows, does NOT mean it is good. An igniter may still glow, but could be too weak to properly operate the gas safety valve.

Replacement parts can be purchased at any of the following websites: All these sites have competitive pricing, so shop and compare. The first three sites listed also have helpful exploded view parts illustrations to assist you with locating and properly identifying any parts you may need.

If you have any questions, please post back with your complete MODEL NUMBER and let me know. I hope this information is helpful to you.

Kenmore gas dryer 80series model 110.c72852101

if you hear the valve clicking but no gas the valve is bad.when the burner lights theres a probe that senses that it is lit and sends a microvoltage back to the controller to tell its lit.check to make sure all ground wires are grounded to a clean metal surface.

After ten minutes the dryer stops and the filter light is lit

The glow-bar system sends electric current through a heating type of element until it glows hot enough to light the gas (this is used on most older style dryers) An I.R. sensor (infrared sensor) determines when the glow-bar is hot enough to light the gas, it then sends a signal to the gas valve to turn on.

To test this system, open the front cover where the burners are; start the dryer in the heat cycle; you should see the glow bar getting red hot (the glow-bar sits inside the burner box just above the burner tubes - there are two types; a round one that has spirals, and a flat one that looks like half of a coat hanger except smaller. If you have a hard time identifying them go look at the pictures of them in the store section) If nothing glows you will need to take a voltage reading across the glow-bar leads (there are 2) as you first start the dryer. No voltage means it's something else. Voltage means replace the bar (a replacement glow-bar should be kept in stock).

If the glow-bar lights and does not go off then the I.R. Sensor has failed. (I usually replace the glow-bar along with the I.R. sensor because one will take the other out, and it's just good maint. procedure to do as such.)

If the glow-bar lights for about a minute then goes off and you do not hear a click sound come from the gas valve (this click sound is the coil in the gas valve opening) then it's probably a bad gas valve coil (see below). If the glow-bar lights, then turns off (in about a minute) and the gas valve clicks on (and you can hear and/or smell that the gas valve is open) the burner tube holes are plugged and/or the glow-bar needs to be adjusted closer to the burner tube. To clean the burner tubes, you can either shoot compressed air into them, or remove them and run water through them. If it's an older dryer it's best to remove them and run water through them so as to get all the compressed lint completely out.
If you have a spark ignition (looks like a spark plug wire from a fact it is.) The way that this system works is, instead of lighting the gas with a glow-bar, it lights it with a spark. To test the system, open the burner cover, turn the dryer on in heat mode, you should hear the gas valve click, and the spark igniter sparking, (in fact, it may even light the gas, but then goes right back off.) If this is the case then most likely the ignition cable is bad. Most people think that just because they can hear the spark, and see the gas light that the cable is OK, however, the ignition module sends a small amount of voltage the opposite direction through ground, through the fire, and through the high voltage ignition cable back to the ignition unit to let it know that the gas has lit. If the ignition cable has a even the slightest crack in the carbon core cable; that small amount of voltage cannot jump that crack like the higher voltage.... So replace the cable. (if it's a weekend and your faced with a downed dryer; either buy one from an auto parts store, or borrow one from someone's car...) The other thing that it may be is plugged burner tubes, if it looks like there is a lot of lint in the burner compartment you may want to try blowing out the burner tubes or removing them and rinsing them out with water.

Check circuit breaker. If it's a 220V machine be sure you have all legs of your power.

Check your neutral leads (I can't tell you how many times I've seen wire nuts come loose...) I've also had alot of power cords (especially 120V) go bad; check them.

Check control fuses, there's usually more than one. Sometimes they put them in the computer control board.

If there is a transformer in the main circuit (There may be two-one for the heat circuit, the other for the control circuit) be sure to make sure you have incoming and out going voltage according to the schematic voltage or it should say on the transformer.

Make sure door switch is adjusted properly or hasn't failed.

Check belt or chain.

Check the conduit going into the motor, sometimes older motors get hot and the mount fails causing them to rotate in their craddle and pulling out the conduit and wires. After repairing the wires you can run a large hose clamp around the motor so as to secure it. This will keep you going long enough until it's replaced.

If the dryer works only while you hold the start button on, it means the start circuit in the motor has failed (120V - 220V single phase system) I've seen people put tape over the button, however this should only be a temp. fix...replace the motor. For a three phase system, it's most likely the start relay is bad.
Be sure to check the main start contactor, these seem to fail quite frequently, they are usually located behind the dryer in the rear control panel.

The igniter glows but nothing else happends

for one thing, the glow plug may not be glowing hot enough, to light burner. if glow plug does not heat up like it should, then gas will not come out. have glow plug checked.

The igniter glows but it wont heat

The burner power circuit is good as indicated by the igniter glowing. The problem now lies in the gas valve solenoid coils failing to open the valves to allow gas to flow be ignited. The coils are located on top of the gas valves one with two terminals and the other with three. Replace both coils to make the dryer heat up again.

Not getting hot. vent line is free of lint. Maytag Atlantis/gas

Chances are the hot surface glow igniter is not working. Most likely it is burned out. Set the controls to dry in high heat and note if the glowing coil does in fact glow. If not, it needs to be replaced. Open the burner access door and then turn the dryer on. Watch inside the burner compartment for the glow coil to light up and glow. If all the controls are set correctly on the front control panel and the dryer is running, but the glow coil fails to glow, you've located the defective part. The glow coil will need to be replaced.
To remove the coil, turn off the gas first. Unplug the dryer from the electrical wall plug. Then remove the entire gas valve as an assembly. The nut on the gas valve to remove it from the gas supply pipe turns counter clockwise. There will be small sheet metal screws used to secure the plate to which the burner assembly parts are attached. The plate holds the entire assembly and is attached to the bottom of the dryer's cabinet.
Next, remove the glow coil from the burner assembly. Take the entire assembled part to the local appliance retail parts store for a replacement coil. Glow igniters are fragile and they break easily. Handle and install the new igniter carefully. Glow igniters are a non-returnable and non-refundable electric component.
Be advised that some new replacement igniters do not come with quick disconnect ends. In this case, it is OK to cut off the quick, disconnect from the old igniter and attach it to the new igniter. Simply clip off the wires several inches above, disconnect the old igniter, attach to the wires of the new igniter, and wire nut the two ends together. Repeat the process to attach the other set of wires and wire nut them together. There is no positive nor negative polarity to be concerned with.
Additional Suggestions: Read the manufacturer's online Web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair procedures, instructions, pictorials and schematics, which may be available online.

Glow plug lights but does not fire gas everything

This is most likely faulty gas valve coils. These electrical coils are located just above the gas valves and when energized, these solenoids open the gas valves and permit the burner to light. If faulty, the gas valves cannot open and the burner cannot light. Due to the difficulty in testing these solenoids, it is recommended that both (all) be replaced at once if any are suspected of being faulty. Hope this helped and best wishes.

Kenmore gas dryer mod.110-73942. burner comes on as normal. After 5-10 minutes running Cycles off, igniter ( new) glows but no burner ign. Also replaced the sensor adjacent the igniter.

The gas valve coil is bad. When the ignitor is glowing the gas valve should open and allow gas in to be ignited. Change the gas valve.

After starting my GE gas dryer , the burner fires and everything seems fine . The burner stays on for a few minutes and shuts off like it's supposed to . After a few minutes , the glow element turns on to...

Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.

Just because the glow bar igniter comes on, does not mean it good. They typically get weak with age and fail to draw sufficient enough current to open the gas safety valves. That is why you don't smell any gas. This is a designed safety feature of the burner that prevents free flowing gas from escaping before ignition. Otherwise, gas would fill the cabinet and then "phoooooom", a huge flash or explosion when the trapped gas finally ignited. I would recommend you read the following link about glow bar igniters:

I know this link is for a gas range, but the igniter types and the principle of operation is the same. If you've had this dryer for a while, I suspect you need a new igniter. Replacements can be ordered on line at Just type in your complete model number and look under the heading for burner assembly parts. Another cause of failed ignition would be the gas valve coils. There are generally two of them on the burner. One is the main coil, while the other is a pilot position coil. When they go bad, however, they typically make a clattering noise. Let me know if you have similar symptoms.

I hope you find this information helpful. Let me know if you have further questions.
