Maytag is so cheap that they can't even install some circuit protection.

My wife was recently complaining that the top oven in our Maytag gas range was not heating.  I found that the gas igniter element was open. Installed a new igniter and it still wouldn't light. Some more troubleshooting found this:



With no circuit protection, the failed igniter had caused some traces to be burned off of the control board. I looked up the part on the internet. It's about $300 for a new control board.

It was an easy fix to bridge the burned traces. Someone without electronics experience would be buying a new board. All because Maytag was so cheap that they didn't put a $0.50 fuse on the board. Or even worse they may have decided that the lack of protection would help them to sell more new ranges.

Looks to me like they DID install a fuse!  :-// :-DD

Is there one igniter for the entire oven or multiple?

Looks like some use a sparking style, and others a glow-plug heater style.

The range has two ovens. There are two hot surface igniters (glow plug) in the upper oven. One for the oven and one for the broiler. The lower oven has a single hot surface igniter. The top burners use the spark gap igniters. I should probably replace the bottom oven igniter. It has about the same amount of use as the top oven. I might not be so lucky if I have another shorted igniter. It's lucky that the short didn't damage the relay. I looked up the relay part #. Mouser electronics lists it. It's made in China and on many months back order.

ah the myth of the PCB fuse strikes again

real fuse : vaporizes wire in a closed tube that contains the byproducts. Nice clean disposal with no exposure.
pcb trace fuse : vaporizes some fiberglass, epoxy, copper and colorant and vents it in to your kitchen. Get to scrubbing strange chemicals, son

 :palm: nom nom chemicals

Kinda feel like its just a tad not well thought out. The company risk matrix factors me in as expendable ....
