Regulator Removal and Replacement

Before replacing the regulator, first check QuickFinder for service
documentation regarding regulator diagnostics.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
NOTE: When replacing the regulator, if the range has been converted
for use with LP gas, make sure to install the correct regulator (cap)
fitting. Refer to the instructions in the LP Conversion kit for details.
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. If obstructing access to the regulator, remove the burner support
rail (with jet holder assemblies attached) by following the steps in
Removing the Burner Support Rail, page 28.
4. Use two wrenches (open-end, or adjustable) and hold the large
nut on the regulator steady with one wrench, while you
simultaneously rotate the flared adapter with the other wrench
until you can remove the flared adapter from the regulator (see
Figure 145).
5. Rotate the regulator until you can detach it from the manifold pipe
(see Figure 145).
Replace the regulator if needed.
6.
NOTE: When replacing the regulator or associated fittings, use
pipe sealant on pipe threads only.
