Issue: The hood is making squeaking noise when it's
running.
Possible Cause: The blower fan wheel is offset to 1 side
and touching the casing or unbalanced.
Solution:
How to adjust and replace the fan wheel
• Disconnect the main power.
• Remove the entire hood from its mounting location.
• Remove the duct and expose the blower fan wheel.
Follow these instructions to re-seat the fan wheel:
• Slowly rotate the fan wheel to check which part of
it is in contact with or too close to the casing.
• Rotate the fan wheel so that the blade with two
small cuts is facing you. (
Figure 4
)
• Use a long screwdriver to slightly release the fixing
screw.
DO NOT remove the screw completely. It's very
difficult to put it back in.
• Adjust the fan wheel left or right to the center of
the casing.
• Tighten the fixing screw and plug in the hood to
the main power.
• Run the hood in different speeds to check if the
issue is fixed.
Follow these instructions to replace the fan wheel
with a new one:
• Remove all 4 screws holding the blower casing.
(

• Take out the blower unit.
• Remove all 3 screws and the side grille. (
Figure 6
)

and not in contact with the casing.
• Tighten the fixing screw.
• Install the side grille.
• Put the blower unit back into the hood and tighten
all 4 screws.
• Connect to the main power and run the hood in
different speeds to check if the new fan wheel is
working properly.
