Replaced oven ignitor and it did not work

12 posts in this topic

My Magic Chef oven quit working. The glow plug gets hot and the burner lights but the flame is very low. I replaced the ignitor and it does the same thing with the new one. What else can I check or do I need to call a repair guy.

The burner fires up in time but the flame is low?  Low compared to what?  Would help if I could see a picture.  If the flame really is too low, I'd expect to see other combustion problems:  sooting, yellow flame, etc.  Any of that?

Also, whenn you are saying the flame is too low do you mean it never reaches the temp that you set it to, or just the look of the flame itself appears not to be high enough?

If the flame is igniting it is not the ignitor. If the height of the flame is your only issue BUT the temps are reached than that is not really an issure UNLESS as the Samuri said there are those other problems. Please elaborate a bit for us. Thanks

I will take some pics tonight when I get home from work.

The flame is blue and looks OK but is only about 1/8 inch high. The oven worked fine for a few years and I have made no changes. The flames produce very little heat and would never get to temperature. I thought the ignitor was not allowing the gas to flow properly so I tried replacing it.

I will post the pics tonight.

Thanks

On top of the flame is a metal sheet "flame spreader". Does the blue flame touch that? If not there is a simple adjustment just to increase the size of the flame. let me know.

The flames do not reach the spreader. The flames are very small. The funny part is for the first 4 years I had it the flames were normal and it worked fine. Since it quit I assumed something was broken.

To give an idea of the flame size before I take pics it is about the size of a stovetop burner flame on simmer.

Nothing broken. Maybe clogged.

You will need an adjustable wrench. I will look to see if the Samuri has any pics of what I am talking about but here goes.

On the gas valve itself there is a brass looking bolt for a wrench with the brass part extending out another one inch in a cylinder shape. In the end of the is a VERY TINY hole. This is called an orfice. The actuall end of the burnner slips over that. But you do not have to remove the burner to do this adjustment. If you turn this piece on way you are restrctiong the amount of gas to come through. If you turn it the other way it allows a little bit more gas to come through. Just like tightening up or backing off any bolt. You want to have the oven off. Turn the orfice 1/2 turn like you would be loosening a bolt. Turn the oven on and check the size of the flame. Only do 1/2 turn at a time and check. To high of a flame will cause all sorts of problems. Just get it to spread on 1/2 of the flame spreader.

Please let me know how it goes. Remember to unplugg before the adjustments and then test. Dop this over and over till you get it just right. But do not do this while it is plugged in as there are wires on that valce and if the metal wrench slips a millimeter and touches the wires you will destroy you gas valve and that's expesive.

Take your time, don't rush it, and unplug it each time then turn it back on to test.

That worked!! Thanks

The funny part is how did it work OK before then quit when it only needed adjusting?

You hear about "clean burning gas" however there is all sorts of stuff that clog gas orifices and jets.  We have to clean all sort of junk out of the gas valves in Dearborn heaters all of the time since they get clogged with white goop and rusty looking grainy stuff. Probably got a chunk of junk that clogged it and was blocking the gas to the burner.   Good job, GLC....  :cool:
