The symptoms my dryer is displaying include shutting down mid-cycle, sometimes after a minute or so, sometimes twenty-five minutes in. Some of the buttons on the User Interface are unresponsive but when I enter Diagnostic Mode all the buttons light and the display reads "88" which I think means that there are no stored fault codes. I have checked all the usual culprits with a meter and all the hardware seems to check out.
Answer Hello Anthony,
The "88" in the display indicates that you have entered the diagnostic mode. Opening the door should cause a beep tone and a number and letter to be indicated in the two-digit display. Closing the door firmly should cause a beep tone and the display to go blank or indicate “88”. If any fault codes are present, they will display soon after the initial "88". If no fault codes are present you should check the plug prongs for burned spots which indicate a loose wall outlet, (which requires a new receptacle to be installed, and if the burned spots cannot be sanded down to shiny metal, the cord should also be replaced). If this, the breaker, and the terminal block all check out fine, the main control board 8546219 is the suspect.
What is the difference between part#AP3777740 and part# AP3775978? The are both illustrated as part #19 in the exploded appliance view.
Answer Hello Joe,
These have different color buttons determined by the color of the unit. There are actually three: platinum, biscuit, and pewter. Two are listed since platinum and pewter use the same color buttons.
Dryer button not responding when touched.
Answer Hello Derrick. Check and see if the thermal fuse and the door switch is good on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
