ELECTRICAL FAULT ISOLATION GUIDE

1. WILL NOT OPERATE IN EITHER HOLD OR 60-MINUTE TIMER POSI-

TIONS.

FAILURE

2. OPERATING IN HOLD POSITION BUT NOT IN 60-MINUTE TIMER

POSITION.

3. OPERATES IN 60-MINUTE TIMER POSITION BUT NOT IN HOLD PO-

SITION.

4. WITH COOK INDICATOR LIGHT ON AND STEAM ENTERING THE

CAVITY, TIMER DIAL FAILS TO TURN.

5. BUZZER FAILS TO SOUND AT END OF 60-MINUTE TIMER MODE.

6. STEAM FLOWS CONTINUOUSLY FROM BOILER DRAIN LINE.

FAULT LOCATION a. Incoming power b. Timer c. Door interlock switch d. Wiring a. 60-Minute timer b. Wiring a. Timer b. Wiring c. Hold thermostat.

a. Hold position set on timer.

b. Timer motor c. Wiring a. 60-Minute timer contacts b. Buzzer c. Wiring a. Cooling valve needs replacing b. Wiring c. Thermostat faulty.

TIMER MOTOR

A defective timer motor will cause continuous operation in the TIME mode, with the timer dial failing to return to the

“0 - Minute” position.

To confirm timer motor condition, proceed as follows:

1. Carefully check motor wire leads and tighten loose connections.

2. Turn on power to the steamer.

3. Set timer dial (any setting beyond “0 - Minute”). If operation is correct, the motor will turn the dial toward

“0 - Minute”. If the motor fails to operate, it is defective and the entire timer must be replaced.

4. Shut off power to the cooker

DOOR INTERLOCK SWITCH

Malfunction of the cooker door interlock switch prevents indicator lights from turning on and steam generator from operating when the timer dial is set. If steam does not enter the compartment and the cooking indicator light fails to turn on with the door latch securely engaged, the fault may be in the door interlock switch. Proceed as follows:

1. Turn off power to the cooker.

2. Disconnect wires to the door switch terminals.

3. Connect an ohmmeter between the terminals of the switch. The switch is marked “C” for common, ‘NC’ for normally closed and “NO” for normally open.

4. Actuate the switch by closing the cooking compartment door. If a zero reading cannot be obtained between the C and NO terminals, the switch is defective and must be replaced.

5. Remove the ohmmeter and replace the leads on switch terminals.

TROUBLESHOOTING

INDICATOR LIGHTS

If the cooker compartment functions correctly, with the single exception that the indicator light fails to light during operation, the fault is a defective indicator light. A “burned out” or defective light is verified by using an AC volt-meter at the leads, with input power on the selector switch in the correct position for that timer, the timer set, and the door latches closed. If 240 volts is present, the fault is in the indicator light and requires replacement. If 240 volts is not present, the fault is in the wiring or control components

(selector switch, timer or door switch).

BUZZER

If the buzzer does not sound at the termination of the operator-selected timer setting (timer dial returned to “0

- Minute” position), the fault may be a defective buzzer.

Buzzer operation is verified using an AC volt-meter at buzzer coil connections with input power on and selector switch and coinciding timer dial set at the “0 - Minute” position. If voltage is 240 volts, the fault is in the buzzer, which must be replaced. If 240 volts is not present, the fault is in the wiring or control components (timer or selector switch).

WIRING

Using an ohmmeter, wiring continuity between the connections shown on the wiring diagram is readily verified.

This is best done in stages, removing only those wires required for each continuity check. As each lead is replaced, it should be checked for evidence of corrosion, and cleaned if necessary. All leads must be tightly attached so as to provide a good electrical connection.

ADJUSTMENTS

EXTERIOR PANEL REMOVAL

WARNING

At least twice a year, have an authorized service person clean and adjust the unit for maximum performance.

ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS

The steamer has been factory set so that when it is ON, and during the READY phase, it will maintain water temperature in the steam generator tank at approximately

200 ° F (93 ° C) (just below water boiling point). However, for high altitude locations, an authorized service agency must adjust the steamer to achieve this temperature.

WARNING

To prevent hazard in servicing the cooker, be certain the cold water shut-off valve is closed, and the electrical disconnect circuit breaker for the Cooker unit is OFF before removing side panels.

Access to all internal plumbing and electrical assemblies is from the right side. The right-side panel is removed by removing the bottom screws from panel.

CAUTION

Shut off main electrical power to unit.

DOOR GASKET REPLACEMENT

The cooking compartment door gaskets are made of a silicone-type rubber material that is very durable but subject to wear during normal operation. Should the gasket leak replace it.

1. Open the cooking compartment door.

2. Remove the four screws on the outside of the door frame, and remove the door panel assembly.

3. Remove the six screws from the gasket plate in the door panel assembly.

4. Remove the gasket plate and the door gasket from door panel.

5. Install the new door gasket to the door panel. Replace the gasket plate and six screws.

6. Reassemble the door panel assembly in the door frame using the four screws.

7. Gasket replacement is now complete.

Door may be difficult to close until gasket has compressed to conform to opening. Leaving door closed overnight will compress gasket.
