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 the 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 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.
Correct the problem 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. The brake cannot be repaired and the motor
must be replaced.
If the motor fails to run when power is reaching it, replace the motor because it has burned-out.
Electronics Failure
An electronics failure may be caused by relays, microswitches, capacitors, resistors, interface boards,
wiring, and controls. Troubleshooting electronics is 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 each component for the presence of 120 VAC. Examine the diagrams on
Pages 1-31 and 1-32 to identify components and wiring connection points. (See Page 1-22 for simplified
basket lift schematics.)
