Solenoid Valve Removal and Replacement

The solenoid valves are used for burners with XLO or XHI
functionality, and are accessed from the top of the range.
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 25.
2. Follow all steps in Accessing Components under the Maintop,
page 25.
NOTE: The solenoid can be detached from the gas tube without
removing the control panel. However, to replace the solenoid
valve, first remove the control panel (see Control Panel Removal
and Replacement, page 35).
3. 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 28.
4. Remove hex compression nut on the gas tube that connects to the
solenoid with a 9/16 inch wrench. If possible, simultaneously use a
1/2 inch wrench to hold the nut on the solenoid while removing the
gas tube (see Figure 136).
5. Then remove the compression nut at the other side of the gas
tube to detach it from the jet holder assembly. Be careful not to
bend the gas tube.

6. First make a note of how the wires are connected to the solenoid
valve terminals, and then remove the wires from the terminals.
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 reassembling.
Alternatively, you can photograph the wire connections prior to
disconnecting (for example, with your mobile phone).

7. Rotate the solenoid valve counter-clockwise until the large hex nut
on the solenoid detaches from the XLO valve (see Figure 137,
page 80). Be careful so the plastic O ring inside the large hex nut
does not fall out (see Figure 135).
8. Replace solenoid valve if needed.
