Fragile Components
Be careful not to exert too much pressure on the standoffs or the
control board, as these are fragile components.

the plastic standoffs by lightly pressing the tiny protruding clip on
each standoff, while simultaneously pulling the control board off
the standoff.

4.5.17.2 Control Board Removal and Replacement – Small Oven
This procedure is for the oven control boards of the small ovens on
the 48-inch ranges. For replacing the control boards on the large
ovens of 48-inch ranges or the ovens of 30-inch and 36-inch ranges,
see Control Board Removal and Replacement – Main Oven, page 59.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
1. Follow all safety precautions and steps in Preparing the Range for
Servicing, page 21.
2. Follow all steps in Accessing Components under the Maintop,
page 21.
3. If obstructing access to the small oven control board, remove the
burner support rail (with jet holder assemblies attached) by
following the steps in Removing the Burner Support Rail, page 24.
4. Remove all wire connectors from the control board relays and
terminals (see Figure 111 and Figure 112).
NOTE: It is always recommended to label and tag all wires, wire
connectors, and harnesses prior to disconnecting them so as to
correctly identify their connections/locations when re-assembling.
Alternatively, you can photograph prior to disconnecting (for
example, with your mobile phone).
