We’ve got an old Montgomery Ward gas range oven. Recently we found out that the oven won’t reach a hot cooking temperature. I turned the oven setting to broil, and looked under the oven and observed that there was no flame coming from the broiler burner. I ordered a new valve and ignitor set from a local appliance parts retailer. After installing the new ignitor, and valve assembly, I turned the oven to “broil”, I found the same problems to be occurring again even with the new ignitor\valve assembly. I already sank over a hundred dollars in to this oven with the purchases of the two new parts. I would really like to keep from having to toss this oven for a compariable used one. Is there anything I am over looking? Could there be a problem with a thermostat?or a thermocouple? The range top works fine and gas flows freely from the valve under the gas range, but for some reason doesn’t “light” in the broiler burner. I could use some help, on this one, I am getting tired of not having complete home cooked meals. thank you:confused: 
I’ve never seen a Montgomery Wards model number like that. Theirs usually start with 3-letters. What you posted almost looks like a Tappan model number but might be missing 2 numbers at the start. Eg. [SIZE=“4”]12-[/SIZE]2442-12/510640
But what was the ignitor doing???
You can read about the various types of oven ignition systems and how they are suppose to function at the following link:

The ignitor is glowing and it si new so it should be drawing enough amps. I can’t understand why the oven the burner isn’t lighting? I mean what else can it be if both the ignitor and valve are brand new?
Is it the correct one that matches the oven valve’s specifications? There are two common ignitor types, each of which draws different amperages as described at the link I previously supplied.
Is the gas valve releasing gas into the oven burner?
If gas IS being released into the oven burner but that gas is just not igniting, a blockage in the oven burner or the gas ports closest the ignitor could be the cause. Either that or the ignitor might not mounted properly.
If gas is NOT being released into the oven burner, a blockage in the tubing leading to the oven gas valve might be a possibility.

There is no impedance to gas flow through the supply line
On the pipe that supplies the gas to the ignitor to light, there is a small slit that is located directly under the ignitor, I "widened"it some what prying it open a bit with a flathead screwdriver
the valve and ignitor assembly are both new and SHOULD be properly matched, amperage wise
Unfortunately I don’t have a an ammeter, only a mutlimeter, I will look around for one.
This problem couldn’t involve the thermostat? Could it?
All the thermostat does is provide power to the ignition circuit. If the ignitor is glowing the control system is doing its job.
