Ot Gas Oven will not light.

[David/toledo]

The Glow plug comes on and will stay on but doesn't light. Looking for ideas on where to look. For what is wrong I am guessing a gas switch. You know the old story the wife wants a new one do to the fact that it is 20 years old and I would does perfer to fix it seeing Work has been SLOWWWWW.

If this gas oven has a standing pilot light and it won't light, it would be a bad thermocoupler (the thing the flame touches(sp)). This could still be the same problem with the newer electronic ignition gas ovens. I have no experience with the new electronic ignition gas ovens. Other then to say I have new one and the damn thing is a pain. Now if/when our power goes out we can't cook anymore..


Sorry for the rant.

Are things so slowwww that they shut off your gas?
I would be checking for an additional valve for the oven.
Or, is the gas turned off to the entire unit.
Maybe you wife has turned it off to get a new one.
Can you smell gas anywhere?
Good luck
Regards Walt...

Your use of the term "glow plug" leads me to believe you don't have a pilot light, but rather one of those miserable ceramic type igniters that are in series with a solenoid that controls the gas flow. The original idea, of course, is that if the ceramic lighter is open, i.e. burned out, then there is no current flow through the gas solenoid, therefore it does not open, therefore you don't fill the room with gas, etc., etc. Also means the turkey stays cold.

While you normally burn out the igniter, killing a solenoid is certainly not out of the question. Trace the wires back from the igniter, and they should lead you to the gas solenoid. Make sure you have continuity through it. If not, the mystery is solved.

Ya no polite light.

David..Had the same problem as you describe...glow ignitor works but the main burner won't come on. Researched the problem and can tell you its the ignitor. As they get old and from gas contamination by-products form the internal resistance changes. The ignitor is in series with the gas valve and its a safety device to prevent gas from flowing to the main burner. Cost is @ $45.00 for the ignitor and a few minutes to install a new one yourself. Check out some of the appliance web sites for do it yourself repair...ton's of good info. Regards, Mark in Buffalo

Absolutely no content, but funny anecdote -

Last week, I thought our oven went boots-up and wouldn't light. There was no pilot, couldn't find the thermocouple to test, no piezio spark, I was thinking I was at a diagnostic dead end, and would need to call a service agent.

Turns out that while cleaning the stove top, the selection dial for the oven had been inadvertently turned to "time cook" -- i.e. a count-down timer to start the oven at a pre-set time. Once returned to it's normal position, oddly, the oven functioned normally.

swimbo'o oven got to where it would sometimes light or not....Electronic igniter would glow but the gas valve sometimes would stick. When I would turn it on and it would not fire up I would take the drawer out from under the oven, the gas valve was behind it, tap on the valve with a screw driver handle....just like magic it would burst to life. I ordered a new one on line, looks just like the old one, fits perfect, and now 6 months later it does the same thing as the old one........Grrrrrr.

I had the same thing. Think I replaced the igniter and a valve. Worked fine.

25+ year old stove, I'm now on the original gas valve and
the third ignitor. These are actually silicon carbide.
High resistance when cold, so the gas valve stays shut.
When the thing glows red, the resistance has dropped enough
to allow current to pass to open up the gas valve.

The red-hot surface lights the gas via a catalytic reaction.

My failure mode is always a dead open at the ignitor itself.

They're about 75 bucks at any appliance store, there are
as far as I can tell, only two real types: the round ones
and the square ones.
