ROBLEM
Rotisserie does not revolve.
C
AUSES
One or more of the following:
(a) motor failure,
(b) circuit failure,
(c) gearbox failure,
(d) broken chain,
(e) loose sprocket, or
(f) the overload device has tripped.
P
ROCEDURE
(a) Inspect the cooking compartment to be sure that the
rotisserie assembly has not jammed. If the assembly is okay
and the load is evenly balanced, turn the rotisserie switch to
the “off” position and let it sit for about five minutes, then
press the reset button on the contactor/overload assembly
and try the rotisserie switch again. If it still does not revolve,
proceed to Step (b).
If there has been a rack jam you will also need to proceed to
the next step. Other damage may have been incurred,
however, such as damaged racks or rotisserie wheel pins, or
rotisserie shaft. The racks can probably be straightened and
reused. If they cannot be reused, replace them with new
racks. The shaft can usually be repaired by heating it with a
torch and twisting or bending as needed until it is straight.
In severe cases, however, you will need to replace the shaft by
cutting it free from the welds that secure it to the rotisserie
wheels and installing a new shaft and rewelding it.
(b) Make sure that the circuit breaker feeding the pit has not
tripped. If it has, reset it and try to operate the rotisserie. If
it trips again or if the rotisserie shaft still does not rotate,
proceed with the next step.
(a) Open the motor/gearbox access door. If the gearbox output
shaft is rotating but the sprocket is not, then shut the circuit
off and tighten the sprocket onto the shaft.
NOTE: Make sure the 1/4 inch square key is in place on the
output shaft. If the chain is broken, repair it. If the chain is
moving, check the rotisserie shaft sprocket and make sure
the key is in place in the keyway.
(d) If the motor is running but the output shaft on the gearbox is
not rotating, proceed to Step (e). If the motor is not running,
proceed to Step (f).
(e) Shut the pit circuit off and remove the motor and gearbox assembly by
removing the bolts holding the gearbox onto the base plate. Remove the motor
from the gearbox and inspect the coupling between the two. If it is not broken,
replace the gearbox.
