With the modular basket lift, 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 Issues
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 Issues
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
1-70 and 1-71 can identify the components and wiring connection points.
