Replace igniter

You could have a weak glo bar, that is common or the main oven gas valve could be bad.You have to trouble shoot and find out which it is.If you happen to have a seperate broiler in that range that has a separate glo bar you can use it in the lower oven to see if it will open the gas valve.Hope this helps.

you could have a bad ignitor check that it is actually igniting the gas and you can see flame, also check the cavity sensor a probe that sticks into the oven at the top usually on the left top corner but if the bake cycle works with good results them it is ok
check for flame when it starts give it a mibute to ignite, if it does not then you need to replace the broil ignitor.

It could be that the ignitor is weak and only partially heating which could be causing the gas control valve not to open and allowing the gas to flow into the broiler burner tube.

I would also suggest you see if you can smell gas to confirm that the gas supply valve is actually opening up. With the oven door closed, turn on the broiler and after 20-30 seconds of having the ignitor glowing red, turn off the broiler control and open the door and see if you can smell gas, if not it could be either a weak ignitor or a faulty gas control valve.

I would suggest that before you start ordering parts, you swap out the oven ignitor with the broiler ignitor to verify that the broiler ignitor is the problem. It could also be the broiler tube has a blockage of some sort possibly from cooking debris, that is preventing gas from flowing into the tube.

Here's a diagram for your unit along with the parts list.

Hope you find this very helpful and best regards!

you may need new coupler on pilot system

i have a magic chef gas range. broiler work, burners work, fan works when you turn the oven on, but oven does not get hot. could it be the electronic ignitor or does even have one.

Hi, Even tho the ignitor is glowing, it can be bad. It has to pull enough amps to open the gas valve. This is very common problem. I can get you the part and or prices if you could get me the model#
If I can help further, please let me know.

Thanks
Vic

I called a repairman it was the igniter.

You have two ignitors one for bake and one for broil your bake is not working

Ignitor is very fragile and may have cracked.
