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:

MODULAR BASKET LIFT

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.
