6.9.6 Broil Burner Components – Removal and Replacement
The removal and replacement procedures for the broil burner
and the broil burner hot surface igniter (HSI) each require access from
the front and back of the range. The procedures are the same for the
small and large ovens.
Be sure to check QuickFinder for relevant information, documentation,
and correct part numbers when replacing any of these components.
Hot Surfaces
The oven broil burner and interior surfaces of the oven may be hot
and can cause burns. Do not service the range when these
components are hot.
Fiberglass
Wear gloves when handling fiberglass insulation.
Eye Protection
To protect your eyes from debris, it is recommended to wear
protective eye wear at all times when removing or installing
components inside the oven cavity, such as the broil burner, HSI, or
HSI retaining bracket.
Gas Leak Testing
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.
