Bruce C Round Lake , IL December 03, 2014 Appliance: Maytag Freestanding-Double Oven-Gas MGR6772BDW Maytag Range Mgr6772bdw: No heat on bottom unit of double oven. How to replace Bake Igniter (Gas Oven). Replaced the bottom Ignitor Bake. I've never performed this type of repair before and it only took 10 mins. I am not very savvy when it comes to fixing anything (especially appliances), but this ended up being a simple repair. Only difficult things was getting a couple of the screws off (they were a bit rusted/corroded). Followed the instruction video on appliancepartspros.com. Very pleased with appliancepartspros.com, ordered the item and it arrived next day. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
