1.8.7 Improper Basket Lift Function
Modular Basket Lifts
Older Decathlon Series fryers may be equipped
with modular basket lifts. The modular
basket lift consists of a notched rod to which
the basket lift arm is attached, a reversible-
drive gear motor, and a pair of roller-activated
microswitches. The gear motor engages the
notches in the rod, moving it up or down.
Microswitches at the upper and lower limits of
movement stop the motor when the basket is in
the full up or full down position. A manual
(push-button) controller or computer controls
voltage to the system.
Problems with the modular basket lift system
can be grouped into three categories:
• binds and jams;
• motor and gear wear;
• electronics failure.
Binds and jams. Noisy, jerky, or erratic movement of the lifts is usually due to lack of lubrication
of the rods and their bushings. Apply a light coat of Lubriplate or similar lightweight white grease
to the rod and bushings to correct the problem.
Another possible cause of binding is improper positioning of the motor, which prevents the gear
from correctly engaging the teeth in the rod. To correct the problem, loosen the screws that hold the
motor in place and move it forward or backward until the rod has just enough slack to be rotated
slightly.
Motor and gear wear. The most likely problem is erratic motion of the lift due to a worn drive
gear. Failure to keep the lift rod and bushings properly lubricated will cause unnecessary wear of the
gear. The problem is corrected by replacing the worn gear.
If the lift cycles correctly but fails to remain in the up position, the problem is a failed motor brake.
A failed motor brake cannot be repaired and requires replacement of the motor itself. If power is
reaching the motor but the motor fails to run, the motor is burned out and must be replaced.
