How do I replace a Control Thermostat in an Electric Wall Oven?

The oven thermostat is used to regulate heating inside the oven. If it fails to turn on the oven burner to heat the oven, or if it fails to turn off the burner when the oven is at a set temperature, replace the thermostat.

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 mounting screws from the thermostat.

    The control knob is used to set the temperature in the oven. The two mounting screws on either side of the stem can be removed with a Phillips screwdriver.

  3. 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 disconnect 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.

  4. Disconnect the oven control thermostat.

    The control panel is behind the mounting screws that hold the top panel up. If you want to properly connect the new oven control thermostat, you need to take a photograph of the wires and mark them with masking tape. Pull the oven control thermostat out of the back of the control panel if you have enough slack in the wires. Use a pair of needle-nose pliers to remove the female spade from the male spade leads on the oven control thermostat.

  5. Remove the thermostat.

    The back of the oven should be removed. The oven sensor bulb and sensor tube can be removed from the back of the oven. The sensor bulb and tube can be removed from the back of the oven. Pull the sensor bulb and tube out of the oven from behind the oven. The thermostat must be removed.

  6. Position the new thermostat.

    The oven control thermostat should be in the control panel. Attach the sensor bulb from the control panel to the oven. There is a new oven sensor bulb and tube.

  7. Connect the thermostat.

    The wires need to be connected to the thermostat. The front of the control panel has the oven control thermostat on it. Attach the mounting screw holes and tighten them.

  8. 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.

  9. Reattach the control knob.

    The new oven control thermostat has a control knob on it.

  10. 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: needle-nose pliers, Phillips screwdriver, work gloves.
