We could no longer set the temperature on our wall oven after doing a self-cleaning cycle. The touch panel did not appear to be working properly. The technician confirmed this. He also said the control board needed to be replaced because the digital display was dim. He told me the unit could not be repaired because replacement parts were no longer available. We would need to buy a new oven. As it turned out, the control panel did not need to be replaced. The digital screen was just dusty. Once I cleaned it off, it looked and worked just fine. I had, incidentally, told the technician it might be a good idea to get rid of the greasy dust on the control board, but he ignored this. We did not need to replace the oven either. I told the technician we could probably get a replacement part for the touch panel from another company. That was indeed the case. The technician would not order that part, however, because it had not been authorized by Whirlpool, the maker of the oven. As I mentioned to the technician, the important thing was to find a part that worked properly, authorized or not. I do not pretend to be an expert on the subject, but I imagine Whirlpool would not authorize any company to make parts for their appliances that did not involve a licensing agreement, their logo on the panel, and additional fees for testing at Whirlpool. I ordered the part from Fixyouroboard.com, which has received nothing but good reviews. The company tests every part they send out and offers a two-year warranty . They provided a video link on how to install the touch panel. This required turning off the breaker switch that powered the oven, a little manual dexterity, and a few common tools. The repair was completely successful. We like the feel and placement of the touch-panel buttons better than the original buttons from Whirlpool. A comparable replacement for our oven would have cost around $1,000.00. If we had followed the recommendation from Tony's Appliance, we would have lost a lot of money.
