Could not have been any easier thanks to INSTANT REPAIRMAN on PartSelect. The site indicated the electronic board was the problem in 99% of cases. The Maytag repairman had come by earlier indicating the problem could be fixed for $500 or we could have a new hood installed for $2500. Fortunately, I decided to give it a try myself. We ordered the part as per the recommendation on this site, turned off the electricity, switched the electronic board with the new one taking care that all wires matched (actually drew a little diagram), and flipped the switch. It worked! 20 minute installation, personal gratification and $500 richer. Priceless! Thanks PartSelect and thanks Instant Repairman!!!
