This dryer only works on time only doesn't work on others selection. Is the dryness control board the problem.? Thanks.
Answer Roger, Yes, Power to the timer motor on the automatic cycles is controlled through a triac on the dryness control board. Make sure you order the correct part based on the series number(first 2 numbers of the serial number) or you'll have the wrong part and other issues, or check and cross reference the part number on the board assembly. Also check and make sure the connectors in the wire harness make good, tight contact on the pins on the dryness board and that there is a good solid neutral to the dryer.
The timer knob does not rotate. I've heard it could be the timer control or the sensor. The dryer does work and dry clothes. Must stop manually. What do you think?
Answer Hello Steve,
The way that you can test the dryness control board is the disconnect the sensor wire from the sensor bar. If the dryer runs for about 20 minutes, then shuts down or timer advances the the electronic control is good and the problem lies in the sensor bar. Check the sensor bar or clean with alcohol. The reason for cleaning is that some fabric sheets will coat the sensor bars 33001809. If you do not have continuity then your sensor bar is bad and needs to be replaced. If the timer still does not rotate or the dryer does not shut off after 20 minutes then you have a bad control. This unit came with 2 different boards depending on the series number. The series number is the first 2 digits of the serial number. If first 2 number are before 20 then you would need 33002734 and anything 20 and after is 33002905. You can test this with a multi-meter TJMA-DMT3.

Is the AP4044037 Sensor/Chime the correct part to use for Ser Num 19533185CG? Thanks.
Answer LK, according to the model/serial number the replacement chime switch is part number 33002732. Thanks!
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
