Caloric Pilotless Wall Oven not working
Posted 24 May 2005 - 04:16 PM
The ceramic ignitor glows orange but no gas comes through the burner. It acts as if a thermocouple isn't allowing the valve to open but I can't find a thermocouple. Not sure if its somehow built-in to the ignitor. Anyway the themperature controller and light seem to work. It calls for heating when the dial is set for a temp above the warmth caused by the ignitor running.
Do you think its the ignitor and if so, how do I test? I have it out and can check it with a meter. Alternately, do you think it could be the square gas valve looking thing on the right side behind the face plate? I think this would not allow gas to flow if the two wires coming out aren't completing a circuit. Can I jump these as a test?

-the light that works as expected is the indicator light. (The oven light works too.)
- the square gas valve looking thing that is a suspect is a "safety valve".
- there is a thermocouple in the cooking comparment to keep the oven at the setpoint. When I meant I couldn't find a thermcouple, I meant at the burner. I guess I was thinking along the lines of a water heater.
Anyway, any thoughts? How do you test the safety valve? Jumping the leads did NOT have any effect.

The only way to know for sure is to use an amp probe and see the amp draw of the ignitor. If the ignitor at least glows you know the safety valve has continuity and also the t-stat and that it's most likely getting 120volts as needed.
The thing that you are calling a thermal couple in your oven cavity is the oven t-stat sensor that senses the heat in the oven and tells it when to turn on/off.
This should be the ignitor for your oven: CLICK HERE
And, about jumping the leads on the safety valve, I don't know what you did or mean by jumping the leads but if you sent 120volts direct without the ignitor in the circuit you have fryed the safety valve also. If you have fryed the safety valve the ignitor will no longer glow, so if after whatever you did the ignitor is still glowing your safety valve should still be ok.

Yep. That's my ignitor and it glows a very bright orange but I wouldn't say white. How many amps should the ignitor be pulling? Should it be tested when its on and hot?
I did use a jumper as a test to connect the two wires coming out of the safety valve thinking that if I closed that circuit it would open the valve and allow gas to flow. The good news is that I reinstalled the ignitor and it still glows bright orange.
Thanks again. I'll definately be ordering what I need from you guys.

See this page for more information and specifications on these ignition systems.

This was exactly the info. I needed. My ignitor drew slightly under 2amps instead of the 2.5-3.0 amp specification. Glad I didn't become one of those boneheads you refer to in your repair revelation and waste money replacing the valve.
I placed the order with you guys. Thanks.

My igniter looks like this: http://www.repaircli...sp?R=154&N=2198.
My question is, to replace the long ceramic igniter, do I have to access the rear of the oven where there appears to be a removable access cover or do I take apart the heat shield and just pull the old igniter out through the front of the broiler and then just attach and slide the new igniter into the back wall of the broiler and reassemble the heatshield?
Thanks for your help!
