Ignition and Control system. The float assembly switches, the timer, the preheat
thermostat, and the TIMED/MANUAL switch control operation of the 115 VAC
components.
The transformer's secondary supplies 24 VAC power to the Gas Burner and Ignition
and Control system.
In units with the
Key Pad Control Panel, an additional transformer provides
24 VAC
to the electronic timer.
STEAMCRAFT 10 TIMER CIRCUITS
All model SteamCraft 10's have either Key Pad Control Panels or Dial Timer Control
Panels. Key Pad Control Panels have electronic timers. Dial Timer Control Panels
have mechanical timers. Either type of timer controls the steaming cycle when the
unit is in the TIMED mode.
• In units with the electronic key pad timer, a 24 VAC transformer supplies power to
the timer. The compartment thermal switch prevents timer countdown until the
compartment temperature rises above 190°F. A buzzer within the electronic timer
signals the end of timer countdown.
• Units with the mechanical dial timer use a separate 3-second timer and buzzer to
signal the end of the cooking cycle. These units do not have a compartment
thermostat.
ELECTRICAL CIRCUIT COMPONENTS
This section briefly describes ihe major SteamCraft 10 circuit components and their
functions. Refer to the drawings in Chapter 7 for the installation location, assembly
details, and parts ordering information for each of these components.
When servicing, repairing, or replacing any component, use only Cleveland Range
authorized repair parts and procedures. Check that the repair part has the correct part
number and is compatible with the power supply rating on the SteamCraft 10 Product
Identification Plate (Chapter 1). Verify proper wiring connections of newly replaced
parts before energizing the unit. Refer to the schematic and wiring diagrams on the
unit or at the end of Chapter 7.

The terminal block provides connection points from the external electrical supply to
the steamer.
• Model 24-CEA-10. The three-terminal block has connections to the transformer
and heater contactor.
• Model 24-CGA-10. The two-terminal block has connections to the transformer
and operating component circuits.
