You may have a simple matter of a weak igniter. Just because an igniter glows, does not mean it is good. They do wear with age and eventually require replacement. 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 – 90 seconds from the time you start the dryer to the time it takes for the gas to ignite.
: 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.TWO BASIC IGNITER TYPES
Carborundum (Cylindrical in shape) – needs to produce 2.5 to 3.0 amps for the gas safety valve to work.
Norton (Rectangular in shape) – needs to produce 3.2 to 3.7 amps for the gas safety valve to work.
NOTE: There is a UNIVERSAL FLAT BAR igniter on the market as well, that can be used as a substitute if the igniter type that came with your range is not available.
The igniter typically goes bad in one of two ways, the igniter either stops glowing completely, or becomes weak over time and doesn’t produce enough current to open the gas safety valve (in this case the igniter will still glow but the manifold still won’t light
Longer ignition times can be another symptom of an igniter possibly going bad.
You can purchase a replacement at any of the following websites:
The first three sites on the list also offer some excellent exploded view diagrams of the appliance.
If your replacement igniter comes with a connector plug that does not match your appliance, you will be instructed to cut the old plug off and splice the wires together using ceramic wire lugs included in the kit. Do not use standard wire lugs as they will melt.
If the model number is correct, the part number for a replacement igniter on this dryer is either 4391996 or 33002789. The part number depends on your SERIAL NUMBER. If you need assistance determining which one to use, post back with your serial number and I can confirm it for you.
I hope this helps you.
