No heat in dryer

Hello,
Your dryer is heated by gas and what is happening is,when the coils that open the gas valve work when they are cool but once the dryer is running and the gas valve coils get warm they wont work,this is pretty typical of a bad gas valve coil.Replacing the coils will fix that.To replace the gas valve coils,UNPLUG THE DRYER, use a putty knife and place in the seam between the main front panel and the small lower front panel AT the corners and depress the clip that holds small panel to main panel.On the right side of the base frame behind the small panel is the burner asm. the coils are held to the gas valve by a bracket remove that bracket and replace the coils, they are black round shaped and one has 2 wires and one has 3 wires the plugs pull off and can be push onto the new coils with just a small amount of pressure.
The part # for the coils is 279834 They can be purchased at your local appliance parts store or online at;

I hope i have helped you to be able to repair your dryer,

If the thermal fuse blew you would have no heat, I would suggest to make sure you have a clean vent system to assure the dryer can breath. Simple test, disconnect vent system and run dryer, if the vent system is the cause the dryer should heat. if the fuse is blown you will not get heat. If the dryer heats at first then stops heating, I would lead you to the coil kit on top of the regulator, then can fail but allow some heat at first. Once they get warm they can fail to reopen the gas valve (regulator).

This is usually due to the two gas valve solenoid coils sitting on top of the gas valves, one with 3 prongs and the other has 2. The coils work fine when cool but one or both are weak and fail when get heated. Both coils must work to open the two gas valves in order for the dryer to fire up. The coils are not repairable and the only viable solution is replacing both of them. Replace the solenoid coils and it should solve the problem.

Hello there:
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 fus

Gas dryers utilize a gas valve, ignitor assembly, and a series of coils mounted on the gas valve to provide heat and safety. The gas valve coils are the usual suspect when it comes to a "No Heat" complaint. I have provided a checklist from www.repairclinic.com, for your convenience. They also provide disassembnly diagrams and repair parts.

Firstly, ascertain that you have made an adequate "Heat" selection, then read on:

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.

Looks like the gas valve coils are failing. This usually begins to happen later in the cycle as the dryer has run for awhile. You will have to have the coils replaced.

If it does not heat , and you already checked the burner and the ignitor, then it is probably the thermal fuse at the back of the appliance.

See the following suggestions from Repairclinic:

If this is a gas dryer, you probably have bad valve coils, they can work intermittently, usually for the first part of a cycle, but when they heat up the internal resistance gets too high and they fail to open the gas valve. Once they cool off, (by continuing to air dry) they will work again for a few minutes. They will also make a buzzing/rattling (maybe "metal" ) noise as voltage is applied. For any Kenmore gas dryer, get part #279834 it contains both valve coils. Very easy to replace. Another possibility is that your duct work is plugged, check airflow. Hope this helps.

Most times I replace the coil assy. on gas control valve. OR could be the sensor.Or both.
