Extremely slow warming CGS3760ADW Magic Chef oven

21 posts in this topic

Our Magic Chef CG53760ADW gas oven takes nearly an hour to heat up to 325.

From what I've read, I'm guessing this is probaly the electronic ignition?

Thanks

How long does it take for the GAS to come on. That is, do you see an orange glow for a minute before the flames ignite, or much longer?

The couple times I have been able to observe the oven, it has had an orange glow for a fairly long period after the oven was started - 10 minutes or so.

if you can, remove, the "Floor" of the oven, there should be 2 screws, in the rear, of the oven cavity. If you pull those out, and remove the cover, then you can get eyeballs on the flame. It is very possible, that the ignitor, is weak, and its taking a while to draw the proper amperage to start the gas flow. This can also be tested with an amp meter, clamped around one of the wire leads from the ignitor, to the gas valve, it should draw about 3.3A if im not mistaken.

If you choose to use the amp clamp method, and the Ignitor does draw proper amperage then, you may have a bad gas valve. I really doubt that the gas valve is bad. Many times I have learned the hard way that a weak ignitor is the cause of oven woes. You can also check the gas valve by using the Broil setting. The broil ignitor will come on and then shortly after you should have a flame, this will verify that the gas valve is good, and a weak Bake ignitor is the cause of your oven woes.

The orange glow is the bake ignitor, and if it takes 10 minutes to open the gas valve, then it would be very wise to replace the Bake ignitor.

Started the oven three times today; first time took the ignitor about 30 minutes of glowing prior to ignition, second time about 4 minutes glowing prior to ignition and the third time about 8 mintues of glowing prior to ignition.

BTW, RegUS_PatOff, are you a fan of your local Sprecher brewery?

Magic Chef model CGS3760ADW oven worked perfectly till this afternoon when it suddenly won't ignite. Replaced the oven ignitor 2 years ago when oven exhibited long pre-heat times and un-even heating. Today ignitor does not heat at all.

Before I simply order parts - any particular troubleshooting if current ignitor shows continunity when I work on it tomorrow?

Thanks

If you have ~120VAC to igniter but it won't glow replace the igniter.

This Magic Chef over is giving me fits with an intermittent ignition. The ignitor is showing about 200 ohms and every time it doesn't ignight, I am showing 120V to the ignitor and the 200 ohms. The oven won't ignite for a day or two and then suddenly it works perfectly. I did replace the ignitor about 2 years ago, but..........

This intermittent work/not work is driving me crazy.

Thanks for any suggestions.

can you do a double check on that model number. how long does it take before the flame gloriously appears when it decides to show? is the igniter bright and healthy or sickly and sad faced? guessing a weak igniter.

Check the amp draw at the ignitor when it is not lighting. Flat ignitor a need 3.2 - 3.6 naps to open valve and round igniters take 2.5 - 3.0 amps to open safety valve. If you have the amps and the gas valve is still not opening then you have a bad valve. If you don't have the amps you have a bad ignitor.

About a minute when it ignites. Really bright whiteish orange. When nothing, beautiful black iginitor.

Oven worked like a charm yesterday - Mom said nada today - stone cold. When Mom can't bake, bad day.

I'll run an amp check and then go forward.

A couple weeks ago posted a question regarding intermittent oven ignition. I've about worn out a multimeter trying to troubleshoot this issue.

When the oven lights, we are getting 120V, 240 Ohm thru the ignitor and drawing about 3.1amps to the gas valve. Peachy.

Then the oven decides a cold meal is in order and everything is stone dead since we do not receive 120 v.

However I've discovered that if you push the "bake" then "set temperature" button, the oven does it's sometimes ignite, sometimes not routine - HOWEVER -

if you push "bake" "set temp" then "bake" again, the oven ignites time after time. I've checked the owners manual and it states to start oven, you push "bake" then "set temperature", NOT push "bake" again after setting temperature.

My chief baker swears that she only has had to push "bake" "set temp" before all this came up.

Is this intermittent ignite issue trying to tell me that a control board is going to be history?

I read all 4 of your topics about this oven. Did you ever replace the ignitor? Maybe the connections are the issue.

3.1 Ohms does mean replace the ignitor.  Make sure not to touch the part that glows, or it will fail prematurely.  Given that you can return the part if you order it through this Web site, it is time to stop analyzing and just replace it.
