I have a Magic Chef model cgr3760adh that the oven and broiler won't light.

Its 8 to 10 years old. Has worked fine. Its 8 to 10 years old. Has worked fine.

The oven igniter may glow but that does not necessarily mean that it is working. You would have to measure the amps draw. Flat igniters should be between 3.2 - 3.6 amps at the gas valve. A new igniter should be less than $50 online. Given the age of the oven this is most likely the culprit since they usually last less than 8 years. If it does not glow white hot, it will not open the gas valve. A faulty valve could be the problem but I'd test the igniter first. Hope this helps
