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
(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.
(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
blue 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.
(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).

Note: the following steps require a skilled
technician for safety's sake. There are
dangerous moving parts (chain, sprockets,
etc.) which can cause serious injury.
