Hello, I need some help to fix my Gas dryer. When I turned on the dryer, I noticed the sound of rolling in the box. But the dryer is not heated up at all. Manufactuer / Model : Kenmore Gas Dryer / 74992301 I browsed the internet. Some experts mention that we need to measure the continuity of the components. Therefore, I opened the dryer and check the continuity of the igniter, radiant, coil valve and thermosat by the ohm meter. Here is the measured value for these component 70 ohm for the igniter 0.2 ohm for the radiant sensor 0.2 ohm for the thermosat 3 leg coil valve : more 1k ohm 2 leg coil valve : more 1k ohm I will appreciate your help Thank you and Best regards Hochul Kim

I suspect your gas valve coils are going out and need to be replaced. They can work when first used but later in the cycle one of them quits.

I would check the heating element...it probably shorts out once it gets hot and then touches metal that shorts it out...

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 dryer is gas check out this gas no heat tip....

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

check out this electric no heat tip...

Hi, If you have a gas dryer.
The most common problem with a gas and no heat is the ignitor going bad...

Here is a tip that I wrote about that problem...

If your dryer is electric..
There could be a number of different problems...

Hello Friend, Your problem is very simple to fix. You're dryer needs a gas valve coil kit. To replace coils just remove front of dryer body and look below drum you will see the gas valve. The valve coils are located on top of valve (two little round black cylinders). It's simple, just remove the two screws from the little metal bracket that holds them down, unplug the wires from them and just lift them straight up off of the valve. Take notice that one has 3 wires and one has 2 wires. Just replace with new coils and plug wires back in and re-fasten metal bracket. Your dryer will run like new. Happy to help, Tim. And please don't forget to give me your rating for my help.

Hello there:
here is a discriptive way of trouble shooting the dryer and it lists the common components that will normally fail if the element has not failed first
Gas Dryer DiagnosticsThis picture shows the main parts of a gas dryer's burner systemthat can fail. Understanding each component and it's failure mode canreally help diagnose a problem with a gas dryer.
Ignitor failure: The drum turns but the igniter doesn't glow, thereis no clacking sound as the gas valves open and there is no flameignition sound.
Radiant Sensor failure: The drum turns but the igniter doesn't glow,there is no clacking sound as the gas valves open and there is no flameignition sound.
Gas Valve Solenoid failure: The drum turns and the igniter glows andgets turned off but there is no clacking sound as the gas valves openand there is no flame ignition sound.
And another component failure to be aware of, but that's not shown here, is the operating thermostat:
Operating Thermostat failure: The drum turns but the igniter doesn'tglow, the gas valves don't open (there is no clacking sound) and thereis no flame ignition sound.
And here's a picture of other components to ohm out if you're getting no heating at all:

Hello Friend, If the burner on your gas dryer is igniting the first few times producing heat in the early part of the drying cycle and then Doesn't ignite the remainder of your drying cycle, It's pretty safe to say that you need to replace the valve coils. Here's general information pertaining to the replacement of your valve coils: Your problem is very simple to fix. You're dryer needs a gas valve coil kit. To replace coils just remove front of dryer body and look below drum you will see the gas valve. The valve coils are located on top of valve (two little round black cylinders).

Hello Friend, Your problem is very simple to fix. You're dryer needs a thermal fuse and or gas valve coils, and maybe an igniter all three are very simple and affordable to replace. To replace the thermal fuse just remove back cover of dryer and look down where the air blows out. Now, just to the left where all the wires are you will see a white plastic part with two wires plugged into it. This part is called a thermal fuse. Just remove these wires and replace the thermal fuse. Now, if this don't solve the problem you will need a gas valve coil kit. To replace coils just remove front of dryer body and look below drum you will see the gas valve. The valve coils are located on top of valve (two little round black cylinders). It's simple, just remove the two screws from the little metal bracket that holds them down, unplug the wires from them and just lift them straight up off of the valve. Take notice that one has 3 wires and one has 2 wires. Just replace with new coils and plug wires back in and re-fasten metal bracket. Your dryer will run like new, if it doesn't then you will need to check the igniter. The igniter is attached to the end of the burner assymbly by one screw and a simple two wire plug. Inspect for breakage, and replace if needed. Happy to help, Tim.

Hi .No The Solenoids Are Turning The Gas On . I would Check The Venting . Remove The Venting Clean All Venting. Thanks The Appliance Doc
