Doug B Owosso , MI May 22, 2020 Appliance: Maytag 30`` Electric Built-In Cooktop MEC7430BB00 Maytag Cooktop Mec7430bb00 / : Burner didn't work. How to replace Infinite Switch (Dual Surface Element). I called Appliance Parts Pro's support line to verify I was ordering the rights parts (new Burner unit and switch) and they verified I did. The parts were packaged well and shipped quickly. I had no problems removing the cook top and replacing the parts. Thank you for your help and knowledge. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
