GE SCB 1001, ZSC 1001 manual Demo Mode, Standard Test Load, Fault Codes, Display, Failure Detected

Demo Mode

The Sales Demo mode will allow dealers to demonstrate all oven functionality with one exception: No power is ever applied to any of the halogen lamps, heaters, mag HVT or inrush relays while the control is in sales mode.

The sales mode will be initiated by holding the “POWER / TEMP” and “START” pads down at the same time for a full 3 seconds. This mode can only be entered during the initial “SELECT TIME” display that occurs when the unit powers up after a long (>60 seconds) power outage. When sales mode is initiated, a 2 short-beep signal is sounded and all oven functions will operate with the following exceptions;

1.No power shall ever be applied to any the heaters, Halogen lamps, magnetron HVT or Inrush control relays. The control relays for any of these loads shall not be switched during sales mode.

2.The DEMO icon will be lit whenever the unit is in sales mode regardless of settings or the feature being selected.

The sales mode is cleared by holding the “POWER

/TEMP” and “START” pads down at same time for a full 3 seconds. The sales mode can only be cleared during the same initial “SELECT TIME” display that occurs when the unit powers up after a long (>60 seconds) power outage. After 5 seconds elapse, all functions of the oven will return to normal operation.

When power-up occurs, software will check the special sales demo identifier code. If the code is set, then the oven will stay in the sales demo mode. This will prevent the unit from powering back up to a normal mode if power to the salesroom had gone off .

Standard Test Load

The standard test load is one liter (1000 ml) water with starting temperature of 59°F ~ 75°F in a 1000 ml beaker. (DO NOT USE ANY OTHER LOAD OR DISH AS RESULTS WILL VARY FROM STANDARD.)

PERFORMANCE TEST FOR MICROWAVE

1.Use Clear Glass Tray and the beaker. (Part # WB64x0073)

2.Record initial water temperature.

3.Run at high power for 2:03.

4.Record end water temperature. The minimum difference between the initial and ending temperature should be: 32°F @ 120V.

Fault Codes

The smart board monitors various operations and can detect certain failure modes. In the event of specific failures, cooking will be terminated, a four beep signal will be heard, and a fault code will be displayed.

Pressing the CLEAR pad will remove the fault code display, unless the failure is a shorted keypanel switch. Detection of a failed sensor will have no effect on features that do not use that sensor.

F4 (open or shorted humidity sensor) and F6 (high cavity temperature during microwave cooking) codes apply only to microwave cooking. The chart below indicates failure modes which can be detected and displayed.

Display	Failure Detected
F1	Oven cavity thermistor open
F2	Open cavity thermistor shorted
F3	Key panel shorted (> 60 seconds)
F4	Humidity sensor open or shorted
F6	High cavity temperature detected
	during microwave oven cooking
