SECTION 1. TROUBLESHOOTING

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 pr operty damage.

CAUTION used with the safety alert symbol indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

W ARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious 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.

If maintenance procedures are not followed corr ectly, injuries and/or property damage could result.

SECTION 2. MAINTENANCE

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
