Gas valves open but gas will not ignite

I have a kenmore gas dryer. The igniter comes on, the valve opens, however the gas does not ignite. There is a strong gas smell inside the dryer and at the vent. I recently replaced the thermostat and coils.

Sears kenmore gas oven - bought a new oven safety valve because the oven ignitor was coming on, but gas valve was not opening. Put new safety valve on, doing same thing, if you tap the valve on top, it...


Hello,

The reason the igniter would come on yet not let the gas flow is because the IGNITER IS WEAK and not drawing the proper power to open the gas valve. Replace the igniter nad the oven will work without having to tap on the valve

I HAVE A KENMORE 80 SERIES GAS DRYER. WHEN YOU TURN IT ON IT FIRES UP AND GETS HOT. AFTER A WHILE (5-10 MIN'S) FIRE GOSE OUT AND WILL NOT COME BACK ON.


Hello,
If what happens is the flame comes on when it first starts,after the flame goes off you see the igniter glows then goes off but no flame,the coils that open the gas valve are working while thier cool but once the dryer gets running,when warm to hot the gas valve coils wont open the gas valve so when the igniter comes on and no flame the coils have failed to open gas valve and need to be replaced, all manufactures use the same coil supplied by one parts supplier, and them not opening the valve when warm is a very common occurence regardless of what brand gas dryer it is.
The part number for the coils is 279834 they could be picked up from your local appliance parts store for under $20 or online at;

Model 110 72712101 kenmore gas dryer will come on run about 2to3 minutes then goes off after a short the glow will come on again but will not relight.


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. Here is a link to the parts you need.

Kenmore 300 gas dryer..not getting hot only nine months old


Hello there:
If your dryer doesn't heat, check these: IIgniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too. The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one. Gas valve coils 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. Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

Kenmore 700 series gas dryer .runs but no heat


There are several things that can cause this problem. It could be a defective hot surface igniter, inop thermostat, bad gas solenoid valves ect. You will first need to check and see if the hot surface igniter is coming on. You can verify this by turning on the dryer and then watching for the hot surface igniter to start glowing from the burner inspection hole at the bottom of the dryer(or remove the front/back panel if no window). It should glow very bright. Then after it is glowing to it's brightest point you should then hear a click(the sound of the gas valve solenoid opening) and the burner should come on. There are two gas valves in the system as a safety so you could have one valve that is bad. When the gas valves are charged they should be magnetized on the top of the valves. You can also give these valves a light tap to see if they are sticking. The gas valve solenoids and bad igniter are the most common cause of inop gas dryers. It could also be a bad thermostat or high limit cut off switch is open. Take a look at the dryer and let me know what you find. Also be careful doing any work on your dryer without the proper tools and knowledge. You could hurt yourself from electrical shock or explosion if you are not careful.

I have gas dryer that igniter glows but gas does not ignite drum turns vent is clear


Likely you have a bad gas valve coil set. There are two small black cylinders on top of the gas valve... if these are bad they will not open the valve to let gas come in.

Gas pilot light


Most modern appliances that use gas as an ignition source do not have a pilot light. The gas and ignition is controlled by a burner assembly with a gas safety valve. In theory, the way the burner ignites is:

1. You push the start button, the drum begins to turn and the igniter on the burner assembly begins to glow.

2. The igniter must reach a predetermined current potential in order for the gas safety valve to open. Once this current potential is reached, the gas safety valve opens.

3. Gas begins to flow into the burner manifold, and you have ignition.

NOTE: It can take 30-90 seconds for the burner to ignite. As an igniter ages, it may take longer.

The reason burner assemblies are designed this way (especially in dryers) is to prevent free flowing gas from filling up the appliance cabinet without ignition. If such a condition existed, the could be a potential explosion hazard.

If you are experiencing problems with ignition, the first thing to check is your igniter. The do wear out with age and are fairly simple to replace.

NOTE: A glowing igniter does not necessarily mean it is good. If it is weak from age, it may never reach the required current level to open the gas safety valve.

If you have questions, or require additional assistance, please post back with your complete model number (located on a nameplate around the door opening on most dryers) so I may be able to provide you with better service. I hope this helps you.

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.

Dryer will heat up then gas shuts off and will not re-ignite.


That is a sign that the coils that open the gas valve have become weak. The one sitting toward the outside has a 3 wire connector and works with the igniter. When worn out they may open the gas valve for about 3 second or sometimes not at all.If you look inside the door and get me the model number I will get the part number for you. Some people sale a kit of 2 each. Let me know, Sea Breeze
