I have a Maytag MDB7601 that is 10 months old and waiting on its second repair under warranty for the same symptoms. Last time the touchpad internal parts had issues. Repair lasted 5 months and now acting up again. Mine has the recessed (hidden) touchpad with the only touchpad in the front being the on/cancel button. Try to turn off at breaker and wait 1 hr. after turning back on it will sometimes work again temp.
