The direct spark ignition (DSI) module is used whenever the electrode
is the igniter for the bake burner (whether or not the broil burner uses
the HSI or electrode as the igniter). See DSI Module Removal and
Replacement, page 63.
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. Remove the backguard (see Backguard and Island Trim Removal

connector) out from under the front of the range.
NOTE: You do not need to lift the bake burner out of the burner
box.
3. Use an adjustable wrench to remove the compression nut at the
elbow connector, and then detach the gas flex tube from the
elbow connector (see Figure 225, page 112).
4. While holding the hex nut on the orifice with an adjustable wrench,
rotate the elbow connector to detach the elbow connector and
orifice from the bracket (see Figure 226, page 112).
5. Remove and replace orifice or elbow connector if necessary.
Gas Leak Testing
With electrical power off, carefully check for gas leaks at each gas
