Gas Leaks
With electrical power off, carefully check for gas leaks at each gas
component that was removed, replaced, or otherwise serviced using a
gas leak detector (electronic leak detectors are highly recommended)
or bubble test.

XLO Valve Removal and Replacement

Extra low (XLO) valves are for the left, front, left, rear, right,
front, and right, rear burners. They are accessible from under the
maintop and require control panel removal.
NOTE: The XLO valve used for the right, front burner also has extra
high (XHI) functionality, due to a larger orifice size.
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.
3. Remove the control panel (see Control Panel Removal and
Replacement, page 35).
4. Detach the white side connector from the potentiometer by
pressing on the tab, then slide the potentiometer forward to
remove it from the valve shaft (see Figure 140, page 81).
5. Use an adjustable wrench to unscrew the large hex nut on the
solenoid and remove the XLO valve from the solenoid valve. Be
careful not to lose the plastic O ring positioned inside the large
hex nut of the solenoid valve, as it may fall out easily (see
Figure 135, page 79).
NOTE: If you are not servicing the solenoid valve, leave it
attached to the gas tube, and leave its wire connectors attached.
6. From under the manifold, use a 1/4 inch wrench to remove and
retain the valve screw that secures the XLO valve onto the
manifold. Be careful not to lose the rubber washer attached to the
screw (see Figure 139, page 81).
7. Gently lift the protruding part of the XLO valve out of the
receptacle on the manifold. Don't lose the red rubber washer
attached to the base of the valve.
8. Replace the XLO valve if needed.
