6. Use a 1/4 inch nut driver or a 1/4 inch socket wrench/ratchet to
remove and retain the valve screw by accessing it from under the
chassis base, through the corresponding access hole. The oven
door must be opened or removed (see Figure 76 and Figure 77).
Be careful not to lose the rubber washer attached to the screw.
7. Remove the standard valve and microswitch (connected together)
from the manifold (see Figure 78). Be careful not to lose the red
rubber washer attached to the standard valve.
8. First make a note of how the wires (piggyback and single) are
connected to the terminals on the microswitch before detaching
the wires from the terminals (see Figure 78).
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 the wire connections prior to
disconnecting (for example, with your mobile phone).
9. Detach the standard valve from the microswitch by removing and
retaining the screw, and then pulling the microswitch off the
alignment pin on the standard valve (see Figure 78, page
41).
10. Replace the microswitch if needed.
Gas Leaks
With electrical power off, carefully check for gas leaks at each gas
component removed, replaced, or otherwise serviced using gas leak
detector or bubble test.
4.5.4 Solenoid Valve for XLO Burner - Removal and
Replacement
This procedure is for the solenoid valves which are used for the left-
side (XLO) burners.
For the procedure for the grill solenoid, see
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
.
2. Follow all steps in
Accessing Components under the Maintop
.
3. Remove knob from solenoid valve stem by slowly pulling knob
straight out, away from control panel.
4. If obstructing access to the solenoid, remove the burner support
rail (with jet holder assemblies attached) by following the steps in
Removing the Burner Support Rail
, page
.
5. Use a 1/2 inch wrench to hold the nut on the solenoid valve, while
unscrewing the gas tube hex nut with a 9/16th inch wrench.
6. Then unscrew the other side of the gas tube attached to the jet
holder assembly and remove the gas tube. Be careful not to bend
the gas tube (see Figure 81).
