Install new switch. Line up the switch in the opening and connect wires to the matching terminals. Be sure to attach wires to the correct terminals as marked.

Secure and test switch. Replace mounting screws to secure the new switch tightly. Restore power and test each burner control by turning knobs to the ""On"" position.

Replace control knobs. Slide knobs back onto switch stems, matching them to the proper burners. Testing is complete.

Shut off power. Locate the circuit breaker for the range and shut it off to cut power to the appliance.

Disconnect power. Turn off power to the range at the main circuit breaker before working on any electrical components.

Remove fan housing cover. Unfasten screws or tabs to remove the oven's convection fan housing cover.

Disconnect wires. Unplug the electrical wires attached to the existing convection motor. Note wire positions.

Remove mounting screws. Use a nut driver or screwdriver to detach the screws or bolts securing the motor in place.

Extract old motor. Pull out the worn convection motor from the rear of the oven fan housing compartment.

Install new motor. Seat the replacement convection motor where the other was located and fasten securely using the mounting screws.
