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.
	SAFETYALERT 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.
	WARNING 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 correctly, 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
	REPLACEMENT
		To avoid electrical shock or property damage, move the
		power switch to OFF and disconnect main circuit
		breaker, or unplug cord at wall receptacle.
		Light bulbs and surrounding surfaces may be hot.
		Severe burns 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.

2-4. BLOWER REPLACEMENT

1. Remove electrical power to unit.

		To avoid electrical shock or property damage, move
		the power switch to OFF and disconnect main circuit
		breaker, or unplug cord at wall receptacle.
	2.	Using Phillips head screwdriver, remove the side panel
Step 2		closest to the controls.
	3.	Remove electrical wires from wire nuts.
	4.	Remove discs and rod from inside of unit. (See Cleaning
		Section in Operator’s Manual.)
Step 3	5.	Unscrew knob and lift drive-side vent panel up and
		out of unit.
	6.	Loosen thumb screw and pull out on fan blade and
		remove from shaft.
	7.	Using a 7/16" nut driver, remove the nuts securing
		the blower to the unit, and remove blower from unit.
Step 5	8.	Replace with new blower in reverse order.

When placing fan blade back onto shaft, rotate fan blade on the blower shaft, while holding the blower wheel inside the control area. The fan blade should snap onto a pin at the base of the shaft.

2-5. THERMAL SENSOR

REPLACEMENT
	1.	Remove electrical power to unit.
		To avoid electrical shock or property damage, move the
		power switch to OFF and disconnect main circuit
		breaker, or unplug cord at wall receptacle.
	2.	Remove the side panel closest to the controls.
Step 2
	3.	Unplug probe from control PC board.
	4.	Press down on the probe bracket and pull probe from
		bracket, or using 3/8" socket, remove nut securing probe
		bracket to unit and remove bracket and probe from unit.
	5.	Remove vent panels from inside unit. (See Cleaning
		Section of Operator’s Manual.)
Step 3	6.	Install new probe in reverse manner, exposing the probe
		1½” (38 mm) inside cabinet.

1½ inch (38 mm) probe position is important. Improper positioning causes erroneous temperature readings.

7.Plug probe onto P2, a 2 pin connector.
