Broken door micro switch. (unit does not start heating)
37 of 68 people found this instruction helpful.
  • JAMES from BILLINGS, MT
  • Very Easy
  • 30 - 60 mins
  • Screw drivers
Unplug the unit before servicing. Need phillips screwdriver. Open door. Use step ladder to access and remove 2 small screws from top of the room air diffuser at top of unit. Slide diffuser slightly to the left to align the diffuser's plastic tab on the left side to rotate toward you. (The wires for the front control panel are at the far l eft side of this difuser, but difuser is slotted for easy removal). Once the difuser is removed you will see 1 screw at the top that secures the pannel cover on the left side of the unit. Remove screw and slide this panel slightly up and out. This exposes the plastic frame that holds the upper and lower door switches. To locate the door switches and observe how they work, close and open the door and watch the door (bayonets) open and close the micro switches. Do the (red) buttons on top of the switches move up and down when the door bayonets push and release? If the buttons do not "pop" up when opened the switch is defective. The switch frame is secured with 2 screws. Remove screws and rotate the unit out for easy access to the micro switch(s). The internal (spring?) on my unit that is suposed to allow the red (visible) button on top of the switch to "pop" up when the door is opened was broken. Carefully pry the switch outward while being careful to lift the plastic holder-piece that holds the switch in place. Be careful, there is a small pin on the frame, so rotate the switch OUT toward you while lifting (carefully) the plastic holder-piece (you will see it on top of the switch). You can use an ohm meter to test the continuity of the switches. But if the buttons don't "pop" they are defective. Replace switch and reassemble.

  • 30 - 60 mins
  • Screw drivers
Leave the unit installed. Remove 8 screws, 4 on each side of the bottom of the drawer. It is hinged on the back but front will drop down. Remove screws attached to the white slide rails but hold bezel assembly so the spring metal on each side do no break. Look in assembly from the back to front. With a long Phillips remove the screws hold ing the bezel on. 3 screws. Remove old Bezel. Put new on and reassemble using the reverse.
