No heat it starts but the igniter doesnt light the gas

If your gas dryer is not working because it is not heating then you need to check this out. Today?s gas dryers often do not use the simple thermocouple with a pilot to prove the flame anymore. They use a much more complicated method of lighting the burner and proving the flame.

The use of electric igniters has become the standard for many dryers today. The thermostat calls for heat, power is supplied to the igniter, then after a certain amperage draw on the igniter, the gas valve is energizes to open and allow gas to flow starting the flame. As long as the amperage draw on the igniter is high enough then the gas valve stays open till the thermostat is satisfied.

Sometimes the igniter will crack and no current will go through and the igniter will not even heat up or glow. Sometimes the igniter will wear to the point where it will still heat up and glow, but the current draw will not be high enough to allow the gas valve to open. This creates a confusing situation where you look into the dryer and see the glow from the igniter, but get no heat because the burner never lights up. If this is the case then you will need to replace the igniter even though it seems to be okay. The only way to know for sure is to know what the current draw requirements are for that gas valve and to have an amp meter to check the current draw.

The problem is the dryer coils are failing. They tend to fail as they heat up. They are inexpensive and easy to replace. There is a video at www.appliancehelponline.com/servicemanual.html that will walk you thru troubleshooting this. It's a different model but the troubleshooting is the same. You can also enter your model 3 for diagrams and illustrations of your specific model.

Is this a GAS Dryer? Or, an ELECTRIC Dryer?

If this is an ELECTRIC dryer, the following link will give you some advice on how to troubleshoot a no heat problem:

If this is a GAS dryer, the most common failure for heat related problems in a gas dryer is a weak or blown igniter on the burner assembly.

The way the ignition system is supposed to work is like this:

1. Select the dryer cycle and press start.

2. The drum begins to spin and the igniter begins to glow.

3. Once the igniter reaches a certain current potential, the gas safety valve opens.

4. Gas is introduced into the manifold and you have ignition.

NOTE: It can take roughly 30 to 90 seconds from the time you start the dryer to the time it takes for the gas to ignite.

NOTE: This is a designed safety feature of the appliance that prevents free flowing gas from accumulating in your home without ignition. That's why you typically don't hear any gas flowing when you have an igniter problem. You might think you have a gas problem when actually you have an ignition problem.

You can purchase replacement parts (if required) at any of the following websites:

The first three sites on the list also offer some excellent exploded view diagrams of the appliance.

The igniter probably needs replacing and is not igniting the gas or it could also be the coils. You will need an authorized gas technician for this repair. Take care and not chances.

Check the following areas to address this issue.

1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.

If all the above check out ok, replace the timer or, control board.

The gas burner assembly uses solenoid coils in a circuit with the flame sensor to safely ignite the burner. When the dryer starts a heated cycle, the circuit through those components is energized. The igniter glows until it reaches the proper temperature to ignite the gas, at which point the flame sensor trips open and the current flowing through that circuit is diverted to the gas valve coils so the gas valves open, and the burner lights and continues to burn. If the solenoid coils on the gas valves fail, the gas valves won't open for ignition. If the gas valve coils are weak, the burner lights during the initial ignition sequence from a cold start but it fails to light the burner on subsequent ignition attempts. In this situation, replace the valve coils. I Had the same problem with mine and I fixed for like $25.00 US. Its not hard to do look at the video. Either buy your part from them or to get it fast and not out of this world go to "repairclinic.com

my dryer just stoped. when i press the start button it makes a noise and then theirs a small burnig smell if i turn the tumbler it works for awile then back to the dryer being stoped again.

time to replace your gas coils. those are the two round things on the gas valve. chances are the dryer ignites when first started but as the dryer heats up the coils fail and as it cools again the coils work again. make sure you replace both coils
