Question about Whirlpool Dryers

1 Answer

My whirlpool gas dryer will not cycle through on Automatic Dry. When I start the dryer it will ignite and heat up, but then after it cools, it will not ignite again and therefore will not cycle. I have replaced the timer/motor and the cycling thermostat. Any help?

The burner valve coils (2 in a kit) need replaced . After electricity goes thru them , they will warm up , causing one of them to "open" (short internally). It will not work again till the coil cools back down . Only 2 screws hold the coil bracket on , so , they are not hard to change .Don't have to turn the gas off but do unplug dryer . The burner valve is located in the front of the dryer by removing the front panel .

Kenmore Elite HE4 Gas Dryer Shuts off prematurely in the Auto Dry cycle and the Timed dry cycle


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.

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.

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...

Dryer stop heating


Try vacuuming out the intake and exhaust vents for the burner. Lint collected there can block the burner operation. Hope this helps!

Hello there
when a gas dryer will not heat up properly there can be several different reasons i will try to explain them here for you ok
No heat If your dryer doesn't heat, check these: Igniter Gas valve coils Thermal fuse Igniter 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.)

My dryer is not getting my clothing dry. what could be the issue of not drying my clothing?


Blocked air vent. Check where the vent exits to the outside, as usually condensation builds up on the "bird blocker" which attracts dust, which attracts condensation, which attracts dust... etc.

Gas valve coils. The gas valve is opened by two electromagnetic coils. When they start go go bad, they will open the gas valve in the beginning of the cycle, then as the current heats them up, they will quit working, and you will lose heat partway through the cycle.

Igniter. The gas is lit by an electrical lighter similar to the cigarette lighters cars used to have. If the igniter breaks, then the gas valve coils don't turn on, and you get no heat at all.

Whirl pool gas dryer mod ggw 925opw3 will not heat up and dry sometimes at start up it get hot but only for about five min then you can feel cool air stat to com out the outside vent???/


It sounds like you could have one or more issues here. please be advised that only a gas technician should work on gas units. There are solenoid coils that are used in gas model dryers they energize the gas valves allowing gas to flow through to the element igniting it. if one or both of these are faulty you will experience a on and off heat problem. part numbers for the solenoids are 694540 and 694539. another possible problem is that you cycling thermostat located on the blower housing is faulty which gauges the temperature of the air coming from the gas flames. If this is faulty it will not receive the correct temperature reading, therefore not calling for any.part number for the cycling thermostat is 8573028.hope this helps

Thanks

My whirlpool gas dryer will not cycle through on Automatic Dry. When I start the dryer it will ignite and heat up, but then once it cools down, it will no longer ignite again and therefore will not...


UNPLUG the dryer. This model you need to remove the two screws under the lint screen. Now use a flat blade screw drive and insert it in the gap between the top and the front panel and pry the top up. Now locate and remove the screws on the inside of the front panel in upper corners. The front should lift off. You will see the two black coils on the gas valve. When you remove the three wire coil, make sure the sleeve inside it gets put back on the post the coils slides onto.
If I can assist you further, please let me know.

Thanks

Whirlpool gas dryer is not hot .burner ignights but it is not hot enough


If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.

Normally, this is what happens during an automatic cycle:

  • The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.

  • When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)

  • The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

if this helps please give me a fix ya vote
