GE JVM1490WH Installation Instruction

Snip all 4 webs 
on each knockout
panel and remove 
the metal knockouts
for rear airflow.

Locate the two “knockout” plates, on the rear
oven panel, near the top of the oven. 
Using tin snips, carefully cut the web area from
the two holes side-by-side (that secure the
knockouts to the oven). Cut all four webs on both
rear knockouts; this will allow the ventilation fan
airflow to exhaust out the rear of the oven.
CAUTION: Be sure to trim the sharp edges from
the openings after removing the knockout plates.

7 Place the blower unit back into the opening. 

9 Insert the tabs on each side of the damper into

the holes at the inside rear of the adaptor.

Roll the blower unit 90° so that fan blade
openings are facing out the back of the oven.

Blower Plate

Replace the blower plate in the same position
as before with the screws.
