How do I replace a Thermal Fuse in a Wall Oven?

A safety gas valve and glow-bar oven igniter are included in most gas ovens. The components are connected in an electrical circuit. The safety gas valve opens when the glow-bar oven igniter is sufficiently hot to safely ignite the gas. If the oven igniter doesn't glow or isn't hot enough to open the gas valve, you should replace it. There is a separate igniter for the bake burner and the Broil burner in some ovens.

A thermal switch protects the oven from overheating.

The bake element at the bottom of the oven and the broil element at the top of the oven provide heat for baking and broiling in an electric oven. If the oven isn't heating properly, you should replace them.

Follow these steps to fix your issue:

  1. Disconnect electrical power.

    The wall oven needs to be completely disconnected from electrical power.

  2. Remove the wall oven from the cabinet.

    Pad the surface of the table with a towel or cardboard in front of the oven to protect it. The oven is secured to the sides of the cabinet by mounting screws. The cabinet has an oven in it. If you don't disconnected the power supply wiring from the junction box for the wall oven, you will have slack in the electrical conduit. Lift the oven out of the cabinet and put it on the table in front of it. You can use the installation manual to guide you in this step.

  3. Remove the outer back panel.

    The mounting screws that secure the outer back panel to the oven frame need to be removed first. Remove the last of the top screws and press on the outer panel to prevent it from falling. Set aside the outer back panel.

  4. Remove the thermal fuse.

    (not-been-paraphrased) Disconnect the wires from the thermal fuse. Remove the mounting screws from the thermal fuse. Remove the existing thermal fuse and set it aside for disposal.

  5. Install the new thermal fuse.

    Attach the mounting screw holes to the back of the oven. The mounting screws should be inserted and tightened firmly. Push the wires onto the terminals when you position them. Push the female spade connections all the way down.

  6. Reattach the back panel.

    The mounting screw holes need to be lined up so that the outer back panel is on the oven. Attach the mounting screws at the top of the panel.

  7. Reinstall the oven.

    Lift the oven into the cabinet using someone's help. The oven cabinet has mounting screws on it that hold the oven in place.

  8. Turn on power to the oven.

    To restore electrical power, you need to reset the house circuit breakers.

Time required: 60 minutes.

You would need the following tools: 1/4-inch nut driver, phillips screwdriver, work gloves.
