    C106SIX-PT (Pre-August 2020) Oven Troubleshooting

    Bake and/or Broil will not turn on. The display on my unit may be blank
    1. Confirm with a licensed electrician that the unit has been installed properly: Electrical Installation Troubleshooting.
    2. Reset the breaker powering the unit, and start a standard bake cycle.
      1. Turn the breaker to the OFF position.
      2. Wait 5 minutes.
      3. Turn the breaker to the ON position.
      4. Set the clock on the unit.
      5. Select “Bake” using the touch controls on the oven.
      6. The display should show “350 F” by default.
      7. Press “Start.”
    3. If the oven still does not turn on, contact support or a qualified technician for further troubleshooting and diagnosis.
    Bake is consistently under or over the set temperature by more than 30 degrees or Broil does not reach MAX temperature
    1. Check that the unit has been installed properly: Electrical Installation Troubleshooting.
    2. Check that the thermometer being used is properly calibrated. If necessary, purchase a new thermometer.
    3. Check that your personal oven thermometer is placed in the center of the oven, and that the oven has been given sufficient time to preheat, typically 10-20 minutes.
    4. Wait for the oven to cool completely to prevent burns or other injuries. Next, locate the thermostat probe in the top or rear of the oven cavity, which looks similar to this. If the thermostat probe is dislodged or crooked, attempt to reconnect it to the mounting clip(s).
    5. Confirm that any extra foil, materials, pots, pans, etc. are removed except for the ones currently in use for cooking.
    6. Contact support or a qualified technician for further troubleshooting and diagnosis.
    The oven door lock has engaged and will not disengage
    1. Wait for the oven to cool completely.
    2. Reset the breaker powering the oven.
    3. If the door lock still has not disengaged, try unlocking it manually:
      1. Power off the breaker to the unit.
      2. Locate the door lock, found between the door and the front display panel on the right. It will appear as a ¼” thick metal rod extending down into the door.
      3. Using a thin, metal object such as the back of a butter knife, slide the lock to the right.
      4. The lock will eventually disengage and the oven can be used again.
    The backlight for the display has shut off and will not turn back on
    1. To turn the backlight for the display on:
      1. Power on the unit using the power button.
      2. Hold the clock and the – button simultaneously until the backlight comes on.
    The display on my unit is completely blank
    1. The display can sometimes go out during a power surge, or when the oven heats over a safe level and triggers the internal thermal fuse.
    2. To try resetting the unit, restart the breaker that powers the unit.
    3. If the display is still blank, contact support or a qualified technician for further troubleshooting and diagnosis.
