The oven burner was not putting out the BTU's needed so I just purchased and replaced the dual thermal valve. Before I ask for an exchange want to make sure the part is defective and need some more troubleshooting tips.
I have checked the voltages and am getting 120vac at the valve as the knob is moved from boiler to oven. The igniters light up at the right time. The thermostat seems to kick in OK.

The broiler works just fine.
The flow for the oven barely lights the tube

Finally I removed all the gas outlet connections to see how good the gas flow would be if there were no restrictions. (yeah I know)... As expected the boiler gas flow is steady and seems to have a good volume. When hooked up the broiler functions just as it did when new.
When the oven circuit is energized the flow (from the other side of the valve) is much less than that of the broiler. If I throttle the outlet with my finger there is some flow, but when there is no restrictions the flow stops completely. This does not happen on the broiler. Could there be a grounding issue?

It is hard to believe that new part is faulty and am looking for a simple way to bench test or oven test this part. Is there a better wiring diagram that what came with the unit. I

Need a little help.

Sounds like the problem is a weak Bake igniter. Check the current drawn by the igniter while it's on. If it's 3.2 amps or less then the igniter is the culprit.

- The part number for the Bake igniter is AP4091207

Thanks:

I have a Fluke 21 and connected one leg of the igniter circuit to ground and got a reading of .89. If this the correct way to measure the amp draw on the circuit? Is so can I wire the upper igniter in the lower circuit to test it or is that just not necessary.

You have to wire the meter in series with the igniter to measure the current in the igniter circuit. Tne Broil and the Bake igniters in this oven are not interchangable.

Guess I was lucky with the meter and did not have it on the circuit properly. Put it in series and the amperage reading for the lower igniter was 2.54 so will order/replace and advise.

Thanks Gene: Slowly dying igniter was the problem.

You are welcome. I'm glad you were able to fix it. Thank you for the feed back.
