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.
6.7.10 Bi-Metal Gas Valves – Removal and Replacement
Bi-metal gas valves are for the broil and bake burners on all-gas
ranges. There are three bi-metal valves that are accessed at the back
of the range, and one bi-metal
dual valve that is accessed from under
the maintop.
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 22 .
2. Follow all steps in Accessing Components under the Maintop,
page 22.
3. Disconnect the two spade connectors from the bi-metal gas valve,
and make a note of which wires are connected to each of the two
different terminals (see Figure 61, page 47).
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).
4. While securing the (hex) connecting piece at the inlet and outlet of
the bi-metal gas valve with a wrench, simultaneously use another
wrench to remove the compression nut and then detach the gas
tube. Be careful not to bend the gas tube (see Figure 61,
page 47).
5. Remove and retain the two nuts that secure to the bi-metal gas
valve onto the bracket.
6. Remove and replace the bi-metal gas valve if necessary.
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. For bi-metal gas valves you may need the electrical
power to be on when testing for gas leaks.
Use extreme caution
when performing gas leak testing on bi-metal gas valves with the
electrical power turned on.
