The lights work, but the fan is not spinning, is stuck, or is rattling .

□ The thermal protection system detects if the motor is too hot
to operate and shuts the motor down . In this case, the motor
will function properly after the thermal protection system cools
down (after approximately 10 min .) .
□ Check that the fan isn't jammed or scraping the bottom .
□ If nothing else works, the motor may be defective or seized . If
so, replace the motor .
□ Check that the distance between the cooktop and the bottom of
the range hood is between 457 .2 mm (18 in .) and 762 mm
(30 in .) .
□ Check that duct work follows all requirements . Use round metal
duct work with a uniform diameter of 150 mm (6 in .) . The length
of duct work must not exceed 10 .7 m (35 ft) . Reduce the length
of duct work and the number of elbows if necessary . Ensure that
all joints are properly connected, sealed, and taped .
□ Check that the duct does not open against the wind .
□ Ensure that the power is on high speed for heavy cooking .
□ Wind from opened windows or doors may affect the
performance of the range hood . Close all windows and doors
to eliminate outside air flow .
□ Check the light bulb to see if it is loose . If so, tighten .
□ Remove the problem bulb and insert one you know is working .
If the properly functioning light does not come on, the problem
may be the light assembly . Have the light assembly serviced or
replaced .
