Unplug the power cord and shut the gas to the stove. First remove the knobs then remove the 2 screws on either side of the stove. Open the oven door and remove 3 screws on the underside. You can now lift up the glass touch pad, then disconnect the wiring harness. Now lift up to remove the 2 connected igniter switches to expose the burner valves. Use a wrench for the inlet side and a socket wrench for the front side. Pull back on the gas tube and pull out the valve from the manifold. Reassemble everything in reverse order. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
