Steveb for Model Number svd48600b Hi. I've noticed that the screen on the control panel of my oven/range has become dimmer and dimmer over the past few weeks, until a week+ ago when it just went dark. I can still turn the oven on-- it works, all the controls appear to work-- timer, dinger, temps, etc.... I just can no longer see the numbers, or readouts. If I go to do the timer, and it runs its course, and then set an extension time, I can in fact read that. As well as the temps at that point, once that timer exhausts. But once all is turned off from there-- no visible readouts, time, etc.... I talked with one of the customer service techs, and he said that sometimes it helps to "clean" the contacts on the wires. So, I pulled the front panel, and removed the connectors, and then reset them. The buzzer went off, but no lighting. Then, I removed the control panel from the face, and noticed that in the upper left corner of the panel off to the far left, there is what appears to be a scorch mark, like you'd see on an old fuse that had blown. It's about 1/4inch round, and shows silver-ish in color. I posted on the forum back on the 8th-- 9 days ago-- and no one ever responded. Please help me figure out what's wrong here. Thank you.
Answer Hello Steve. Based on the information you provided, it sounds like the oven control WP71001799 is bad and will need to be replaced. Check and make sure there is power coming to the display. If so, and the unit does not light up, you will need to replace the board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
