    Default How to fix oven that won't heat up

    Model Number: CGR1425ADW
    Brand: Magic Chef
    Age: 1-5 years

    Hi - my stove top works. but when tried broil, the broil light blinked for less than 30 sec and then it shuts off. And when bake, the button only goes up to 350 or below degrees. and less than 5 sec, it changes to 100 degrees. And there are no heat comes on when bake or broil. the ignitor was replaced in 2008. Could you please tell me what is wrong and what I can do to repair it? Thanks in advance.

    Start by checking the oven sensor. It should read 1100 ohms at room temperature. If it checks good you'll probably need to replace the igniter. Open the broil drawer and see if it glows red when turned on.

    Thanks for the instruction - checked the oven sensor; it reads about 108x. and I checked the igniter the same way as the oven sensor; it only reads 289. I guess the igniter is the problem. Meanwhile, for some reason, the left side of the oven open up. What is the best way to bolt it back?

    Hello - Thanks for the instruction. Checked the oven sensor; it reads about 108x. and I checked the igniter the same way as the oven sensor; it only reads 289. I guess the igniter is the problem or maybe not since it got reading of 289????
    Also for some reason the lower left side of the oven (where it sits on the floor area) open up. What is the best way to bolt it back together?

    108x?? Is the x suppose to be a 0? You need one thousand, one hundred ohms

    You need an amp probe or a meter that can measure amps. The igniter needs to draw 3.2 to 3.6 amps to open the safety valve.

    Can you take a picture and post it here so I can see what you're talking about

    Hi - Yes, oven sensor reads 1089 or 1084. And I have a digital multimeter. I used OHM area to check the oven sensor. What (which option/dial) should I choose to check the ignitor? ACV, DCV, BAT, DC or DCA? Do I have the option at all? And I will try to take a picture and send you it about the gap.

    It looks like your meter doesn't have that capability. The oven sensor checks good so replace the igniter.

    Beside using the meter, is there other way to check if the ignitor is good?!

    That's why I said to check to see if the igniter turns on and glows red when you turn the oven on. That will confirm supply voltage at the igniter. It might turn on but doesn't mean it's good. They get weak over time and fail to generate the necessary amps to open the oven safety valve. So to answer your question, not unless you have a crystal ball...lol.

    Hello - I got a chance to check. The igniter turns on and glows red. I can feel heat generated but not too much; I think it got something to do with the oven temperature display - it drops from 350 degrees to 100 degrees. And the broil does not seem to work. It shuts off after 30 sec with no heat generated. And I am attached a picture of the oven with the open gap on the left side. Thanks for your help!
