Igniter Works, but Gas won't fire up on Sensor Dry, Will on Timed Dry

The gas won't fire upp on Sensor Dry cycle, but will on Timed Dry. Also, if I stop it while running on Timed Dry, I can restart the cycle, but the Gas won't fire up again. Every time I stop it, I have to start a new Timed Dry cycle to get the gas to fire up.

Help!

PLEASE do not use this dryer until it is fixed. it may be a saftey hazard. From the sounds of it. Your ignitor is only getting a signal every now and then. Now either is a coupler in there to tell the ignitor when to fire and when not to fire. It seems that it is going out only alloweing the dryer's ignition to come on only when a new cycle is started. That is where i would start... check with an appliance repair shop and find out if it will be something you can do your self or if it is something they have to do....
Now I do STRONGLEY recomend that you have a service technicion come on and service your dryer do to the fact that it is a GAS dryer. if something inside the dryer where to get pinched or broken it could cause a bigger problem....
so please take this advisment under consideration....
Thank you.

Gas dryer does not dry in "timed Dry" setting


In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

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.

Problem with the Kenmore 400 series Model 110-77422600. Dryer will not advance through the cycles on either the timed or sensed side, therefore no heat to dry clothes


Most likely could be timer problem or clogged vent and check for any defective sensors or heater
Problem could be related to defective parts or component or wire
and best practice is step by step troubleshooting deduction to isolate problem and rectify problem with replacing defective part

In most gas appliances It could be caused by defective igniter or main valve or control board or dirty nozzle or gas line issue .
Use step by step troubleshooting procedure

For Best safety reason and prevent dangerous consequences and prevent of any hazards of fire and complication with home insurance companies and most important personal safety reason when it comes any gas or propane appliance repair it is best practice to contact insured and bonded local expert gas appliances service centre for best safety reason

Dryer doesn't get hot enough to dry clothes


Hi


Thanks for using FixYa. The first thing that should be checked is the Thermal fuse which is mounted to the exhaust duct inside the back cover. If this fuse goes bad the dryer will not heat and you’ll have to replace it as it cannot be repaired. If this I fine then you’ll need to check the thermostat, igniter and coils. Also as its only 3 months old so it is recommended to use the warranty to avoid any further issues. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

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.)

MDG4000BWW gas neptune dryer The timed dry/air fluff doesn't work until it gets to damp dry or wrinkle release. Works on the other cycles. Have removed lint screen & 4" hose cleaned and vacuumed.


on a timed dry cycle u are selecting the time it will dry
only after the time has run out will it tumble with no heat
on other setting the machine is stopping the heat and putting the machine into a cool down or air fluff mode
sounds like it isworking normally

Dryer start up fine then the gas turns off as ignitor continues


Hi Jim. Perhaps this will help you.

The burner assembly consists of the gas valve, the igniter and sensor, and the thermostats. The gas supplied to the appliance is turned on and off by the gas valve, as follows:


  • First--when you close the dryer door, set the timer, and press or turn the Start button--the motor starts. When it reaches full speed (in about a second) a switch on the motor turns on, which allows the electricity to flow through a simple thermostat to one side of the gas valve.

  • The gas valve then sends power to the igniter, which glows bright orange.

  • As heat and light from the igniter warm up a sensor that's right next to the igniter, the sensor circuit opens, then supplies power to the other side of the gas valve. This completes the circuit and opens the valve.

  • Once the valve opens, the gas rushes out and the igniter ignites it. As the gas burns, it keeps the sensor warm, which keeps the gas flowing.

  • When the dryer reaches the pre-set drying temperature, a simple thermostat turns off the flow of electricity to the gas valve and therefore turns off the gas.

  • When the temperature in the dryer falls about 20 to 30 degrees, the thermostat again allows the electricity to flow through to the gas valve, and the cycle starts over.

If you selected the Automatic setting, the cycle continues until the clothes are dry, then the timer advances and turns the dryer off.

If you selected a timed setting, the cycle continues until the time has expired, then the timer turns off the dryer

Gas shuts off/flame off w/in minutes of starting maytag gas dryer


If you did all the things listed, there are only 2 left that will cause the problem. The cycle thermostat located on the exhaust vent and possibly poor airflow. Remove the connecting vent from the rear and try a timed load. If it works repair the vent exhaust problem. Most cycle thermostats include a thermister that could also be defective causing the short cycle. The flame sensor and gas valve coils would have been the number 1 diagnosis. I would need a model number to more specific.

Gas never ignites in any cycle in a 10yr old Kenmore dryer.


Chances are your igniter has gone bad. It must pull atleast 3.2 amps to open the gas valve and ignite the gas. A new igniter could probably purchased for 20 or 30 dollars.

Speed Queen dryer does not heat...


you have weak gas valkve coils and they will work when cold but after a few cycles they become electrically open and will not allow the gas to flow.
just replace both gas valve coils and that will fix your problem.
