How to Replace the Sensor in Your OGO™ Compost Toilet

Replacing the sensor in your OGO™ system is a straightforward process. Follow these steps to ensure a clean swap and secure electrical connection. This guide covers wire identification, connector use, and reassembly positioning.

Tools You’ll Need:

  • Wire cutters or scissors (for zip ties)

  • Replacement sensor (Contact us if needed)

  • Zip ties (optional, for securing wires after installation)



Step 1: Remove the Old Sensor

  1. Lift and expose the sensor area.
    The sensor has three wires attached to it. You may find it easier to unmount the sensor before unplugging the wires.

  2. Cut any zip ties holding the wires in place.
    Carefully snip the zip ties to free the wire bundle and give yourself some slack.

  3. Disconnect the sensor wires.
    The wires are connected using lever connectors:

    • Lift the orange lever tabs to release the wires.

    • Wire colors:

      • Yellow → Yellow

      • Brown (may appear reddish) → Red

      • Blue → Ground (black or brown in some systems)

Step 2: Install the New Sensor

  1. Prepare the new sensor and unwrap it.
    Confirm the wire colors match the original sensor: yellow, brown/red, and blue.

  2. Reconnect the wires using the same lever connectors:

    • Push each wire fully into its slot and snap the lever tab down.

    • Double-check that each connection is secure and snug.


Step 3: Re-Route and Secure the Wires

  1. Route the sensor cable along the original path, tucking it neatly into the groove or channel.

    • Loop the cable behind the triangular tab section where the cover has a built-in relief for it.

  2. Add fresh zip ties to secure the cable and prevent movement during use.


Step 4: Final Check

Before replacing the cover:

  • Confirm all wires are connected correctly.

  • Check that the sensor is seated and oriented properly.

  • First-time sensor? Make sure it’s calibrated correctly. See our article: [Sensor Adjustment Guide].
