TROUBLESHOOTING THE BASKET LIFT SYSTEM
If the basket lift motors are activating, but the basket lift fails to raise
or lower, or if its movement is erratic, the probable cause is
jamming or binding of the basket lift rods. Apply a light-weight white
grease (such as Lubriplate
TM
) to the rods. If this does not correct
the problem, check for bent or otherwise damaged rods and links,
and for loose bellcranks.
