COOKER PROBLEMS (cont'd)
Steam escapes from compartment during cooking cycle
Initially in the cooking cycle, air is displaced by steam in the compartment through the
Compartment Vent (Thermostatic Trap). Displacement of air is audible by the hissing noise but
should cease when the Thermo-static Trap reacts to the higher temperature of steam entering
the trap. However, malfunction will occur if dirt is lodged internally in metal to metal seat of trap.
Unscrew bonnet from top of Compartment Vent. Remove internal mechanism, cleanse
thoroughly and replace. If malfunction persist, replace Compartment Vent.
As mentioned previously, if the Exhaust Solenoid Valve has a burnt out coil, it will be
incapable of being energized and thus remain open allowing steam to exhaust.
Cooking cycle cannot be activated
Although this appliance has been thoroughly tested, it is advisable to inspect that all wire
terminations are positive and secure before assuming any other malfunction.
When Power Switch in Generator Control Box of Cabinet is ON and steam pressure reading
shows 5 to 6 p.s.i. on Pressure Gauge of Cooker Control Panel and all compartments fail to
function for the cooking cycle, then power obviously is not being supplied to Cooker and wiring
must be checked.
The magnetic coil of the Steam Solenoid Valve may be defective and require replacement. With
Compartment Door open, observe if steam enters compartment when an outside source of (120
V) power is supplied to valve leads. If the valve energizes and steam enters compartment, then
valve is operative and malfunction of cooking cycle is due to either a defective Timer or
Microswitch.
When Timer is dialed. Operating Handle pulled out and cooking cycle will not activate in only
one compartment, then Microswitches may require adjustment of their activating levers or
replacement if defective. With Cooker Cover Panel removed, observe that levers of
Microswitches are fully engaged by Arm of Operating Handle as it is pulled out. Bent Levers
may fail to activate Microswitch(es) resulting in failure to energize valves and/or Timer and must
be straightened (by hand) to assure positive contact.
A defective Timer will prevent cooking cycle from functioning and must be replaced. It is not
recommended that repair of Timer be attempted.
