Here is a list of possible causes. NONE OF THE LEDS LIGHT... Check to make sure that ribbon connectors P3 and P4 are inserted all the way into the machine control electronics board. (To access the machine control, pull the dryer away from the wall and remove the three screws from the top panel on the back. Slide the top panel rearward about 1/2" and lift. The machine control is on the left hand side. P3 and P4 are the "ribbon" connectors going into the board.) A PARTICULAR GROUP OF LEDS DOES NOT LIGHT... A group or combination of LEDs share a common electronic connection. If this connection is open, all of the LEDs in the group will be disabled. If this occurs, replace the entire console electronics and housing. ONE LED DOES NOT LIGHT... Press the button associated with the LED several times. If the LED does not light, the LED has failed. Replace the entire console electronics and housing. NO BEEP SOUNDS... If the associated LEDs do light up, the beeper circuit may have failed on the machine control electronics board. NO DRYER FUNCTION IS ACTIVATED WHEN A PARTICULAR PUSHBUTTON IS PRESSED... If the associated LEDs do light up, the machine control electronics board may have failed. AN E3 ERROR CODE IS DISPLAYED... An E3 error code means that there is a user interface or a software mismatch. It can also mean that a component on the console electronics,or the machine control electronics board has failed.
