perating Conditions

• Oven cavity below 200°F.

• Oven door closed.

• No service codes displayed in the time display window.

• There are no apparent oven operating problems.

Steam Mode (Prior to Serial Number C7439MS)

Refer to the Steam mode circuit diagrams on page 2-13 and/or the schematic

diagrams on pages 2-16 and 2-17 for the following sequence of events.

1. Relays K15 and K13 energized. Boiler drain valve closes and boiler fill valve

opens. Boiler fill begins.

2. Relay K6 energized. Fan motor turns on.

3. When water reaches low water probes, relays K1, K2, K3, and K4 energize.

High water heating elements turn on.

4. When water reaches high water probe, relay K13 de-energizes and boiler fill

valve closes.

5. When boiler water reaches “ready” temperature, relays K1, K2, K3, and K4 de-

energize and water heating elements turn off.
