1-1. INTRODUCTION This section provides troubleshooting information in the
form of an easy to read table.
If a problem occurs during the first operation of a new
rotisserie, recheck the installation per the Installation
Section of the Operator’s Manual.
Before troubleshooting, always recheck the Operation
Procedures Section of the Operator’s Manual.
1-2. SAFETY Where information is of particular importance or is safety related,
the words NOTICE, CAUTION, or WARNING are used. Their
usage is described below.
SAFETY ALERT SYMBOL is used with DANGER,
WARNING, or CAUTION which indicates a personal injury
type hazard.
NOTICE is used to highlight especially important information.
CAUTION used without the safety alert symbol indicates
a potentially hazardous situation which, if not avoided, may
result in property damage.
CAUTION used with the safety alert symbol indicates a
potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
WARNINGindicatesapotentiallyhazardoussituation
which,if notavoided,could resultin deathorserious
injury.
1-3. TROUBLESHOOTING To isolate a malfunction proceed as follows:
1. Clearly define the problem or symptom and when it occurs.
2. Locate the problem in the troubleshooting table.
3. Review all possible causes, then one at a time work
through the list of corrections until the problem is solved.
Ifmaintenance proceduresarenotfollowed correctly,
injuriesand/orpropertydamagecouldresult.

2-1. INTRODUCTION This section provides procedures for the checkout and replacement of
the various parts used within the rotisserie. Before replacing any parts,
refer to the Troubleshooting Section. It will aid you in determining the
cause of the malfunction.
2-2. MAINTENANCE HINTS 1. You may want to use a multimeter to check the electric
components.
2. When the manual refers to the circuit being closed, the
multimeter should read zero unless otherwise noted.
3. When the manual refers to the circuit being open, the multimeter
will read infinity.
2-3. HALOGEN LAMP

Severeburns could result.
1. Push in and twist bulb counterclockwise to remove defective bulb.
2. Use the foam packing around new bulb, and push new bulb into
Step 2 socket. Twist clockwise to lock into place.
When installing the new bulb, do not touch light bulb with
fingers. Wrap the foam packing around bulb to install the
bulb. Failure to follow these instructions could cause dam-
age to bulb.
3. Restore power to unit.
