I have a MDG5500AWW Maytag gas dryer that will not start. I can't even turn off the display. It seems that the start, stop, and buzzer + bottons don't work. I have put the dryer in test mode. To get out of test mode, the directions say to hit the off botton, but it will remain in the test mode. All other bottons do something exept start, stop, and buzzer + bottons. I have changed the door switch and jumped the thermal fues (temporaraly). When I push the start botton, nothing happens. Not even trying to do anything. It looks like the next step is to change the touch pad? My serial number is 69396667GG. Is there any check I can do before forking over $150+ on a chance it is the key pad?
