I have a 5 year old maytag gas oven model MGR5755QDW that will not heat up on the bake mode. The broiler and clean mode both seem to work fine.

I had the same problem with the same model: MGR5755QDW.

I luckily found this thread and ordered the bake igniter suggested by Gene. Ordering was easy and the part came quickly ($55 with shipping). Great experience. I installed the part with the instructions it came with and page 30 of the service manual I found here: http://www.servicematters.com/m...ibrary/docs/16022498.pdf

My notes:
- Be sure to unplug the oven from the electrical outlet and disconnect the gas.
- The oven door comes off easily once you find the little latch on each hinge that rotates forward. I used a screwdriver to pry the latch forwad.
- Study how the old igniter is set up before removing it. That was my best guide to how the new one should be installed.
- The bracket and wire connection options were a bit confusing (at least to me). The bracket the new igniter came preinstalled was right for me, and I ende up cutting off the weird (and different) connectors on both ends (the igniter end and the oven end) and connecting the wires with the included ceramic wire caps.

I never fixed anything like this before, but I just heated my oven to 350. Awesome.

It seems possible that my old igniter was perfectly OK and that my problem was just a loose connection - especially since I had moved this oven recently. But I didn't want to mess around once I got in there to fix it, so I was happy to just buy and install the new part.
