MOTOR AND GEAR PROBLEMS

With the modular basket lift, the most likely problem to be encountered in this category 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 (i.e., goes up, but then slowly settles
back down into the frypot), 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.

ELECTRONIC PROBLEMS

Within this category are problems associated with the relays, microswitches, capacitors, resistors,
interface board, wiring, and controls. The most common problem in this category is a lift that
continuously travels up and down. This is usually caused by a microswitch that is out of adjustment.
Troubleshooting the electronics of a modular basket lift is simply a process of verifying current flow
through the individual components up to and including the motor. Using a multimeter set to the 250
VAC range, check the connections on both sides of the component for the presence of the applied
line voltage. The schematic below and the wiring diagram on page 1-16 can identify the
components and wiring connection points.
