4.6.10 Bake Burner Solenoid Removal and Replacement – Back
of Range
Access for the bake burner solenoid valve is at the back of the range
for all 48-inch models, or from the top of the range under the maintop
for all 36-inch and 30-inch models (see
Bake Burner Solenoid
Removal and Replacement – Under Maintop, page 58 ).
For the procedure for the XLO burner solenoids, see Solenoid Valve
for XLO Burner - Removal and Replacement page 42.
NOTE: For 48-inch ranges, part numbers differ for the main (large)
oven and auxiliary (small) oven solenoid valves.
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
and Replacement , page 73).
3. Remove the back panels (see Back Panel Removal and
Replacement , page 74) .
4. Remove solenoid valves from manifold arm (see Figure 160).
NOTE: When removing a solenoid valve from the manifold arm
(see Figure 160), since it is secured with pipe sealant you may
need to use a hammer to tap at the wrench affixed to the nut at
the inlet valve until it can be rotated.
NOTE: When installing a solenoid valve, the inlet must be sealed
with pipe sealant at the manifold
5. At the solenoid valve outlet, remove and retain the fittings:

When removing the main oven solenoid valve: At the
outlet, a sleeve and a 9/16th inch compression nut attach to
the respective 3/8th inch diameter gas flex tube (see
Figure 161, page 83).

When removing the auxiliary oven solenoid valve: At the
outlet, a sleeve and a 1/2 inch compression nut attach to the
respective 5/16th inch diameter gas flex tube (see Figure 161,
page 83).
6. Replace the solenoid if needed.
NOTE: Use pipe sealant on pipe threads only (for example, on
the solenoid valve inlet (at their outlets on the manifold arm).
Never use pipe sealant on the flair connections or pressure fittings,
such as the flared end of the flared adapter.
