5.1 General Information
This section provides common removal and install procedures
for parts in more than one mode of the Tri-Res. When Part
Numbers differ by Tri-Res Model, the Part Numbers are not
given in this section.
The following procedures are based upon having access to
the Tri-Res on all four side. If the Tri-Res is installed between
other appliances and there is not enough room on the sides for
access, the Tri-Res must be pulled out from its position to gain
proper access.
Care should be taken in moving the Tri-Res so as not to stress
or pull on the electrical, gas, and water connections.
5.2 Cavity Compartment Side Panels
For Part Number see Parts Identification Section.
Removal
1. With a flat blade screw driver remove the two 10-32 screws
on the lower edge of the panel and two at the back edge. The
panel is retained to the steamer by these four screws.
2. Once the screws are removed, the panel can be pulled for-
ward about 1 inch, then raised above the top panel overhang.
5.3 Top Cover
For Part Number see Parts Identification Section.
Note: Under normal conditions the top cover should never
have to be removed. The most likely reason for removing it is if
the panel itself has been damaged by a falling object.
1. Remove right side and left side panels and upper rear panel.
2. Slide the cover forward until clear of the front overhang, and
lift off.
5.4 Tri-Res Control PC Board P/N 160650
1. Remove the four screws from the right side panel. Once the
screws are removed, the panel can be pulled forward about 1
inch, then raised above the top panel overhang and removed.
2. Remove control board housing by removing six nuts from
rear of housing.
3. Unplug the ribbon connectors.
4. Remove the knobs.
5. Using a 5/16” socket, remove the ten 6/32” lock nuts and
remove the board from ten studs on the front panel. Be careful
not to lose the metal washers below the panel.
