Charles S Alabaster , AL July 03, 2015 Appliance: Maytag Gas Dryer MDG6400AWW Maytag Dryer Mdg6400aww: My gas dryer was working but not heating. How to replace Dryer Igniter Assembly. I watched a video on the Appliance Parts Pros website and then took the cover off the front of the dryer. I didn't have an Ohm meter to check the electrical but based on the video decided it was probably a problem with the igniter. I took the igniter off and noticed it had a burnt spot on it. I ordered a new part from AppliancePartsPros.com and the part came within 2 days! I easily installed the new igniter and it worked perfectly! 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
