Whirlpool WMH73521CS Installation Instruction

Depending on your model, the mounting plate may be in the foam 
packaging, or it may be attached to the back of the microwave 
oven.
NOTE: To avoid possible damage to the work surface, cover the 
work surface.
1. Remove any remaining contents from the microwave oven 

cavity.

2. If the mounting plate is attached to the back of the microwave 

oven, remove it and set it aside.

3. Tape the microwave oven door closed so that door does not 

swing open while the microwave oven is being handled.

NOTE: To avoid damage to the microwave oven, do not grip or 
use the door or door handle while the microwave oven is being 
handled.

The microwave oven is set for recirculation installation. For wall or 
roof venting, changes must be made to the venting system.
NOTE: Skip this section if you are using recirculation installation. 
Keep the damper assembly in case the venting method is 
changed, or the microwave oven is reinstalled in another location 
where wall or roof venting may be used.

1. Remove screws attaching damper plate to top of microwave 

oven exterior. Slide damper plate toward the front of the 
microwave oven and lift up.

2. Keep damper plate and screws together and set aside.
3. Remove 2 screws attaching blower motor to back of 

microwave oven.

4. Lift blower motor out of microwave oven.

5. Rotate blower motor 180° so that exhaust ports face the back 

of microwave oven, and lower blower motor back into the
