Maytag GAS range problems


A friend has a Maytag GAS range Model MGR5755BDQ. About 2 hours after a thunderstorm, the clock/timer/oven control stopped working with its readout flashing "F1". She can't find the owners manual.
I've tried a power reset. After about 30 seconds it goes back to F1". I suspect that a lighning surge blew a chip or two. I may have to replace the clock/control PCB and have found online sources but still wonder what the code "F1" means - probably the obvious...
Anyone have trouble codes for these ranges? I've checked the online sites - so far they don't....
------------------------------
Also, the top sealed GAS burners puzzle me.... There is one large opening, about 1/4" inches in diameter in the circumference of each burner. The hole is to the rear, many times larger than the standard burner holes and is not near the spark igniters. The problem is that a large volume of gas jets out of each of these large burner holes, sending a small finger of flame up the side of a pan, sooting up the pan.
What was the purpose of these larger holes?
tnx,
Doug

Check the back of the range. There's usually a envelope there with instructions and/or wiring diagrams you won't find in the manual. I've found info there on adjusting the oven calibration. As to the burners, without more info I can't give an opinion. Carefully check the instructions for converting the range. There might be more info there.

You may find the manual on the Maytag web site. You can also try troubleshooting at www.repairclinic.com
Never saw burners with a large hole as you describe. Sound strange to me.
Oh, and thank you for reminding me why we bought a range with no computer or circuit boards. Our Bertazzoni has no electronics at all.

All gas burners have a large opening to admit air which mix air with the gas before combustion. They generally have a sleeve in the vicinity that can adjust the size of the hole. Move the sleeve until the flame is the standard blue.
Without Oxygen, you'll get a yellow flame signifying incomplete combustion and that will, as you found out, generate soot.
Anyway, your problems about "F1" and this weird flame are not connected.

Thanks for the above but your comments about an opening to admit oxygen is not applicable.
I'm not talking about that.
What I'm trying to describe is a "sealed" gas burner - typical on the top burners of newer gas ranges.
Around the circumference of the burner is a series of small holes allowing gas to jet out - so far - pretty typical.
However these burners have one large hole, about 1/4" in diameter on the circumference that lets a large volume of gas jet out. In a sense a large "finger" of a gas flame that rises up the side of any pan that might be on the burner. These lharger holes or jets or not near the spark ignitor for each burner - so ignition has nothing to do with their purpose.
I know that "F1" computer issue and the flame is not connected.... I didn't imply that it was, did I???
