DOOR REMOVAL (RECOMMENDED)

NOTE: Door removal is not a requirement for installation of the product but is an added convenience.
To remove the door:
A.
  Open the oven door as far as it will go.
B.  Remove hinge bracket from front frame and set aside. The hinge bracket must 

be replaced for proper door functionality when door is reinstalled.

C.  Push both hinge locks down toward the door frame to the unlocked position. 

This may require a flat-blade screwdriver. DO NOT LIFT THE DOOR BY THE 

HANDLE!

D. Place hands on both sides of the door and close the oven door to the removal 

position (approximately 1”–2” [2.5 cm–5.1 cm] from the closed position).

E. Lift the door up and out until the hinge arms clear the slots. 

NOTE: The oven door is very heavy. Be sure  

you have a firm grip before lifting the oven door off the hinges. Use caution 

once the door is removed. Do not lay the door on its handle.  

This could cause dents or scratches.
