How do I replace a Thermal Fuse in an Electric 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.

  9. Turn off power to the wall oven

    The wall oven's circuit breakers need to be shut off. The electric wall ovens use 2 breakers that are often connected together. If the wall oven breakers are not connected, turn them off. Even though the digital display is dead, a breaker can still send power to the broil element.

  10. Remove the broil element

    The oven door can be opened and the oven rack can be removed. The broil mounting screws need to be removed. Remove the supports and screws from the broil element. Attach the wires to the back of the element by pulling the broil element forward. Take care not to let the wires slip through the holes in the back of the oven. If the wires slip through the holes, you will need to pull the oven out of the cabinet and remove the back cabinet panel. If necessary, pull the wires from the broil element with pliers. The broil element can be removed. Remove the door if you can't complete the repair because it gets in your way. Help lifting the door off the oven is needed. The door needs to be on a pad.

  11. Install the new broil element

    The wires need to be connected to the broil element. Remove the mounting screws from the oven cavity and push the ends of the broil element through them. Attach the supports with the screws. Remove the oven rack and close the door.

  12. Restore power to the wall oven

    The wall oven requires the house circuit breaker to be turned on.

Time required:

60 minutes.

You would need the following tools:

1/4-inch nut driver, nut driver set, phillips screwdriver, pliers, work gloves.
