6.3.3 DOOR GASKET REPLACEMENT

The cooking compartment door gaskets are made
of a silicone-type rubber material that is very du-
rable but subject to wear during normal operation.
Should the gasket leak, readjust the door gasket
to the unit or replace it.
Procedure—Replace Gasket:
1. Open the cooking compartment door.
2. Remove the six screws on the outside of the
door, and remove the inner door assembly.
3. Remove the eight nuts from the door gas-
ket mounting plate on the inside of the inner
door assembly.
4. Remove the door gasket mounting plate and
the door gasket.
5. Install the new door gasket (see Figure 7-2
for part number) to the mounting plate.
6. Reassemble the mounting plate with gasket
to the inside of the inner door assembly us-
ing the eight nuts.
7. Reassemble the inner door assembly using
the six screws on the outside of the door.
NOTE:
Remember that the lip on the door gasket mount-
ing plate must fit into the channel on the inside
edge of the gasket to insure a proper seal.
Procedure—To Adjust Gasket to Unit:
To prevent steam leaks around the door, adjust
the gasket tension to cavity. Adjust the gasket by
loosening the six screws on top and bottom of
door, move inner door plate in or out, left side or
right side, and tighten the six screws.

6.3.4 EXTERIOR PANEL REMOVAL

WARNING:
To prevent hazard in servicing the cooker,
be certain that the steam supply boiler is
shut down, the cold water shut-off valve is
closed, and the electrical disconnect circuit
breaker for the cooker/boiler unit is off be-
fore removing side panels.
Access to all internal plumbing and electrical as-
semblies is from the right side and right front. The
left-side panel is removed by removing the bottom
screw and pushing up on the panel until the lower
lip disengages the frame. The panel is shown as
item #25 in Figure 7-1.
The electric control panel, shown in Figure 7-
3, may also be removed as a unit by removing
screws and pulling the panel forward. Removal of
the control panel is completed by unplugging in-
terconnecting wiring at the pin housing.
6.3.5 STEAM AND WATER SOLENOID VALVE
REPLACEMENT
Replacements for the 1/2-inch steam solenoid
valves and the 1/4-inch water valves are available
as complete units from Market Forge Authorized
Service Agencies. It is necessary to replace an en-
tire steam valve when the coil is faulty or the dia-
phragm ruptures. Replacement coils are available
for the water valves. The valves are accessed as
explained in Subsection 6.3.4.
