I have a 10 year old, model SVD48600P Jenn Air, dual fuel range and a loud buzzing is coming from the back of the oven. The stove top burners work and oven light works but no control panel, oven or broiler. Too loud to leave on, so I've turned it off at the breaker. Any ideas? I was thinking transformer or relay?

turn off the main break,them put it back on,that maybe resolve the problem.
I have thi's problem before and that's all I,did.

Your control panel is getting ready to quit. Mine did the same thing, I ignored it and now nothing on the touch panel works. About $150.00 for the part.

SOURCE: Oven does not heat up

We may have found it -  google Maytag Gas and Electric Range Service Manual (1997 models to present) and save it as a PDF to your desk top.  Then print out the PDF pages # 18, 25 & 26, 52, 62 65 & 66.  Those pages sound exactly like the problem we're having, which sounds identical to the problem you're having. We now suspect the issue is the gas valve heater coil and the volts it needs for ignition.  Because without enough volts, the ignitor won't ignite (like, duh?).  The specific PDF page is # 66 in reference to the Glow Bar Operation item # 4. If we're right, we'll need to get three small parts, totaling about $60 in all.  Let's hope this is the solution!

You probably have a 1940's model of Magic Chef. Check for the model number under the lid of the cook top on the upper right hand side of the stove. It should have the model number and the serial number, too. You will need both. The Old Applicance Club run by Jack Santoro is the place to go along with a site called "Antique gas stoves"in Georgia. Good luck with the world of vintage stoves.

there is no reset buton ,but there are some basic things u can do.first u can chk the power coming into the stove.open the back and u will see power cord connected to the stove.use a multimeter and chk voltage between black and red wire.it should read 240v and black/red with respect to green should read 120 volt.if that is ok look for any burnt wires etc.if all is ok then most likely could have control board.
