Question about Weber Genesis Silver B Grill
This advice is for GAS ovens with glow bar type igniters. This is a fairly simple repair that MOST do-it-yourselfers can accomplish with just a little guidance. But, first, here’s a little gas oven theory to help you better understand how to determine if an igniter is bad:
The way the ignition system in most of today’s ovens work is like this:
NOTE: This is a designed safety feature of the oven to prevent 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.
An easy way to determine if you may have an igniter problem is to check BOTH your oven features. If the oven doesn’t light, check the broiler and vice versa. Since both the BROIL manifold and BAKE manifold are fed from the same gas source, but have separate igniters, it’s an easy assumption to make that the igniter may be bad, if one or the other doesn’t light.
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 oven still won’t light). Longer ignition times can be another symptom of an igniter possibly going bad.
For this solution, however, we’re going to assume you have a bad igniter and need to replace it. Follows these steps:
NOTE: The same method applies to both the broiler and bake manifold.
Most igniters cost around $50. Prices will vary with models. I hope this information is helpful.
