Product review (5 stars): a great experience.
Maytag Oven Model MGRG752CDS - Wife told me that the oven wouldn't heat, so I did a little troubleshooting.  Gas burners on top of the stove worked, looked inside the oven and turned the broiler on and could see the igniter glow and then the fire light.  Turned the bake setting on and nothing.  Removed the racks, removed the two screws in the bottom pan, and lifted the pan out.  The flame spreader is integrated on the bottom of the pan so that saved me some work.  Turned on the bake setting and watched the igniter...nada!

Looked at a couple of the other online appliance parts places to make sure I had the correct part number.  Ordered this part from Amazon and paid the extra for one day shipping.  Put a little oil on the screws to loosen them up, then removed them by hand with a screwdriver.  Pulled the end of the igniter wire up through the bottom of the pan and there was enough wire there to get it up through without pulling the stove out.  Unclipped the old igniter, connected the new part, pushed the wires back down through, put the screws back in and ran a test.  Turned on the bake setting, the igniter glowed and we were cooking with gas again!

From diagnosis to replacement with one day Prime shipping was right around 24 hours!  Got the part for half the price of other dealers, even with the  overnight shipping costs, and saved myself $70 to $100 for a simple repair rather than calling a service person.  Overall, a great experience...the right part at the right price, shipped quickly!  Thanks Amazon!
