Levy R Palatka , FL January 13, 2019 Appliance: Maytag Undercounter Dishwasher MDB7749AWM2 Maytag Dishwasher Mdb7749awm2: No lights on control panel unit acted like it was totally dead. How to replace Dishwasher Thermal Fuse. Watched video on checking thermal fuse. Fuse was bad, ordered new fuse and a new control panel because 4 out of the 6 plastic screw posts were broken. Shipping took 2 days!!! Super fast service!!! Installed new thermal fuse, control panel powered right up, so I swapped out new control panel for old one, super easy and quick. Put panel back on, unit works as good as new!!! Thanks Appliance Parts Pros for the fast service and very informative video's on how to do it myself. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
