4.5.17 Control Board Removal and Replacement

The 48-inch range has a dedicated control board for each of the two
ovens.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
4.5.17.1 Control Board Removal and Replacement – Main Oven
This procedure is for the oven control boards of 36-inch and 30-inch
ranges, as well as for the large oven control boards of 48-inch ranges.
For replacing the small oven control board of 48-inch ranges, see
Control Board Removal and Replacement – Small Oven,
page 60.
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 large 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 and retain the screws holding the control board shield
onto the range chassis and then remove the control board shield
(see Figure 111).
5. Remove all multi-pin wire connectors from the control board as
well as the spade connector of the ground wire (see Figure 111).
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).
