Hi, very common problem.

The problem is with the gas coils.
When they get weak, they only come on for about 10 minutes and then the machine will blow cold air. There are 2 of them with one being the booster coil. They come in a pair and run less than $20.

Best of luck. Please e-mail me if you have any other questions.

How to fix a whirlpool gas dryer that tumbles but no heat ?



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.

Whirlpool Cabrio gas dryer does not heat. About every 1 minute it makes a low screeching sound for about 20 seconds. It spins fine but just cool air. I already removed the rear panel and completely...


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.

What is wrong with a whirlpool gas dryer model #LGR4634EQ2 that won't heat and the timer runs down to near the end but not far enough to shut off?


Gas Dryer no heat: or shuts down soon after heating CHECK:

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.

Dryer wont heat for more than 10 minutes when cold


did you clean the vent line?THAT COULD MAKE IT RUN HOT THE AIR CAN'T BLOW OUTSIDE,BUT WITH THE DRYER HAVING HEAT WHEN IT STARTS AND THEN AFTER LIKE 10 MINUTES NO HEAT IT SOUNDS LIKE YOU HAVE BAD GAS COILS,WHEN THE COILS ARE STARTING TO FAIL THEY WILL WORK FOR LIKE THE FIRST 10 TO 20 MINUTES AND WHEN THEY HEAT UP NO GAS,WHEN THE COOL THEY WILL WORK AGAIN,I WOULD CHANGE THE COILS AND CLEAN OUT THE DRYER AND VENT LINE,THIS SHOULD BE DONE ONCE A YEAR SO YOU DON'T HAVE A FIRE AND YOUR CLOTHES WILL DRY ON TIME,EVERYONE THINKS SOMETHING IS WRONG WITH THE DRYER AND ALL THAT HAPPENS IS THE VENT LINE AND THE DUCT WHERE THE LINT FILTER SLIDES INTO FILLS WITH LINT AND THE AIR CAN'T BLOW AROUND GOOD ANYMORE,ALSO WITH A SHOP VAC VAC UP THE LINT WHERE THE BURNER AND MOTOR IS AND THEN SET THE VAC UP TO BLOW AND BLOW THE MOTOR AND GAS BURNER OUT,DO THIS AND YOU'LL HARDLY HAVE ANY PROBLEMS WITH THE DRYER

A whirlpool gas dryer will not heat up


If your dryer is not getting any heat, you need to make sure there is nothing blocking the vent. IE: LINT. Air flow is key to efficient drying. Make sure the dryer settings are appropriate for the clothes you want to dry. The timer selection, fabric selection, and the temperature selection all play important roles in proper dryer operation.
Check the heating element, burner operation, ignitor, thermal fuse, and the wiring (power cord).
• Heating element (For Electric Models)
• Burner operation (For Gas Models)
• Ignitor (For Gas Models)
• Thermal fuse
I WOULD START WITH:
To protect from over-heating, many dryers use what's commonly called a thermal fuse. If the thermal fuse gets too hot, it will blow, and completely shut down your dryer until it is replaced. This fuse is often mounted within the exhaust duct in the back panel. It's about an inch long, and is usually found within a white plastic housing. When fuses blow, it means they have no continuity and no power will flow through it. A bad thermal fuse needs to be replaced. When replacing this fuse, check the dryer vents to make sure there is no lint buildup which can cause the heat to stay trapped and blow the fuse again.
Visually inspect your heating element for any broken or burned areas.Check the coil for continuity with a Volt Ohm Meter. If there's no continuity, it means that the element is bad and you need to replace it.
If the ignitor is cycling without the burner lighting, you probably have defective electrical coils in the gas valve. These coils look like black cylinders with wires coming out the top of them, and are located near the burner valve assembly. When they get power, they open up and allow the gas to get through to the burner. If this is a new installation, make sure the gas valve is turned on.

Dryer runs but won't heat


As the clothes gently toss about inside the drum, a temperature control thermostatic disk regulates the heat. It is set for 160f for cotton and it mounts on the blower housing. As air is drawn into the drum and out the backside of the dryer the heat is regulated by this control. It sends 120 volts to the gas assembly. Right next to it is a fuse. The duct fuse is set to blow at 250f. Should that control fail to open and allow for heat to build to abnormally high temps. Note: the fuse will kill the heat source only on most dryer, the dryer will however continue to run. Lint and vent blockage can restrict the airflow and make the heat inside build to dangerous levels.The control thermostat powers up the heat for a minute then shuts down for a few minutes, then repeats this all throughout the drying process, the gas does not stay on! That would burn the clothes. If both of those items check ok and the dryer vent and lint has been cleaned, I next take a look at the gas assembly. I check the flame sensor first. If the flame sensor is open the ignitor will not glow. If that turns out to be good I next check the ignitor itself for continuity. If it turns out to be good I replace the coils. Those coils cannot be checked because they do not act up until energised. Sometimes the coils will work, get hot and fail, cool down and work again. I have some repair photos: HERE

My gas whirlpool dryer won't heat. Cool air does


Hi

Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.

Please do rate this solution as FixYa and revert for further assistance.

Thanks

Whirpool dryer won't heat up


You need to replace the thermal fuse and the timer. A bad timer will over draw a thermal fuse and cause it to blow.

Please remember to unplug the dryer before servicing

Whirlpool Gold Ultimate Care II: No heat


didc, on a gas dryer, if the thermal fuse blows it will still rotate, but will not heat. Since this is a gas dryer, see if the ignitor is glowing. If it is, then you know the thermal fuse is good. If not, the thermal fuse may be blown or the ignitor itself and thus the reason for no heat. Catriver.7152136.jpg
