Step-by-Step Fix:

1

Disconnect the oven from the power supply at the breaker panel (240V circuit). Verify power is off with a multimeter.
2

Locate the door switch. It's typically near the door frame. Visually inspect for damage or misalignment.
3

Using a multimeter in continuity mode, test the door switch. It should show continuity when the door is open and no continuity when the door is closed.
4

If the switch is faulty, replace it with a manufacturer-approved replacement part.
5

Inspect the wiring connected to the switch for any signs of damage or shorts. Repair or replace as necessary.
6

If the switch and wiring are okay, suspect a faulty relay on the main control board. Replacement of the control board is often required.
7

After repairs, reconnect the oven to power and verify the light turns off when the door is closed. Check the app connection is functional (RSSI > -70dBm).

Technical Overview:

The Whirlpool Smart Oven uses a mechanical door switch to detect door closure. This switch controls the power to the oven light. The switch connects to the main control board, which also monitors oven temperature and relays information to the user interface (UI) and the connected app via Wi-Fi (2.4 GHz, 802.11 b/g/n). Firmware updates are delivered OTA. Power consumption increases when the light is continuously on.

Common Causes:

Faulty door switch (stuck in the 'open' position).
Misaligned or damaged door latch mechanism preventing full switch engagement.
Wiring issue: short circuit in the light circuit.
Defective relay on the main control board.
Moisture ingress affecting switch or wiring (common in humid Canadian environments).
Firmware glitch incorrectly interpreting door sensor data.

Observed Symptoms:

Oven light remains illuminated even when the door is securely closed. No error codes are displayed on the oven's control panel. App reports normal operating state, despite visual confirmation of light being on. Internal temperature sensor reports ambient temperature, indicating the oven is not actively heating.

Technical Recommendation:

Try a 'hard reset' of the oven by disconnecting it from power for 5 minutes, then reconnecting. This can sometimes clear minor firmware glitches. If using a Rogers Ignite router, ensure the 2.4GHz band is enabled and configured for optimal appliance compatibility.

Prevention:

Periodically inspect the door latch mechanism for proper alignment and smooth operation.
Clean the door switch area to remove any debris that could interfere with its operation.
Ensure the oven is installed in a well-ventilated area to prevent moisture buildup.
Keep the oven firmware updated to the latest version. Check for OTA updates regularly using the Whirlpool app. Consider assigning a static IP to the oven on your Bell Giga Hub for increased reliability.
Perform a visual inspection of internal components yearly.
