(f) If the motor does not run, shut the electrical supply to the pit
off and remove the gearbox and motor assembly as indicated
above. Separate the two, energize the pit circuit, and turn
the rotisserie switch on. If the motor runs, replace the
gearbox. If it does not run, replace the motor; however,
check the gearbox by rotating the input shaft manually. The
output shaft should rotate (remember the output will rotate
much slower than the input). If it does not rotate, the
gearbox is also defective.
5). P
ROBLEM
Black residue (carbon) on the meat after cooking or “creosote”
odor
in smoke.
C
AUSES
One or more of the following:
(a) improper wood,
(b) too much wood in the firebox, or
(c) improper draft.
P
ROCEDURE
(a) Check smoke exit flue and the stack and clean if necessary to
remove any obstructions.
(b) If a new supply of wood is being used, check its type and be
sure it is not the problem by using some wood from your
regular supply.
(c) Too much wood in the firebox can cause this problem. Also,
if your wood is dry, it can occur. Soot is produced when
there is inadequate oxygen available for complete
combustion. When you build a roaring fire in the firebox by
using too much wood or wood that is too dry, there may be
insufficient oxygen available. Reduce the amount of wood
you charge into the firebox when this problem occurs.
6.) P
ROBLEM
Rotisserie not revolving smoothly.
C
AUSES
One or more of the following:
(a) the chain is loose,
(b) the gearbox is defective, or
(c) one of the sprockets is not secured to its shaft.
