When I turn on the oven the igniter glows red hot but the gas never comes on and the oven never gets above 110deg.
Answer Hello Kevin. If you are sure the igniter 74007498 is getting hot enough, you will need to change the valve. However, if the igniter is weak, the oven will not lite. Hope this helps.

Had to shut gas off to repair leak. Gas company relit pilot,it stays on but burner won't lite. Why??
Answer Gramps, For that style wall oven, and with the complaint you have described, you most likely have an inoperative flame switch 968-114.
This is more or less an electronic thermo coupler and works very similarly. Unfortunately the part is no longer available from the manufacturer, and we are not aware of a substitute or replacement part.
I have a wall oven that is setup for propane and I would like to change it to natural gas. Can I just change the gas orifice size?
If so, do you have one or know the orifice size?
Answer Hello Charlie! The unit is self convertible. Refer to page 9-10 on the following link for the conversion. Thanks! https://www.maytag.com/digitalassets/MLPDF/Installation%20Instructions%20-%20W10526072.pdf
The igniter does glow red but the burner does not ignite. Is there a thermocoupler and if so could it be bad?
Answer Hello Don,
The ignitor 12400035 is probably bad because if it's only turning red, it isn't hot enough. You see, the ignitor has to pull 3.2 to 3.6 amps in order to build up a strong enough magnetic field to open the gas valve. When it's pulling enough current, it will glow bright orange to almost white hot. The current can be measured with a clamp on amp meter TJCL1100. To do this, clamp the amp meter on one wire that leads to the ignitor.
A thermocouple is not used with an ignitor. If the issue isn't the ignitor, it will be the burner 74005025 or the safety valve 74001929 or both.
The ignitor gets so hot that at 6" away I have to move my hand back. But no flame? Does this sound like the valve is bad?
Answer Hello Cathy. Test for 3.2-3.6 volts AC at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. You can test this with a multi-meter TJMA-DMT3.
