I have replaced this part three times. It has a burn mark at r3 on the board each time. When this happens dryer does not shut off?
Answer Hi Wayne. When the control console is rotated up and secured, the wire harness inside
the console could push the resistors together causing them to short. Failure of the control board leads to dryer shutting down and the sensor lights turning off. Manufacturing moved the main harness toward the back of the console away from the sensor board and tied the harness to existing wires. See photos below. Using a new wire tie, bundle the chime board harness. A new chime/sensor board was introduced last December with two resistors elevated above the control board.This change involves a revision to the wiring harness, schematic, Chime Board and Dryness Display Electronic Control Board, which is used for sensing the dampness of the clothes load. Now the boards have been combined into a common Chime/Display/Electronic Control Board. Continue to use the earlier control boards on machines built prior to the series change.Series 23 MDG8400AWQ, MDG8400AWW, MDE8400AYQ, MDE8400AYW,MDE8400AZW. Please contact the manufacture as they need to revise your unit if your serial # is 23....... or more. Thank You.
I tought the timmer had gone bad so I ordered new timmer installed, and timer does not rotate. What is the problem?
Answer Hello Bobby. Test across brown and white wires on the dryness sensor board 33002734. If there is 120 volts there and the timer does not run, replace the timer. If there is not 120 volts there, you will need to trace and see where your loosing power at, if the unit is heating correctly. 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
