Diagnostic steps
Check the hood supply
Confirm the hood is powered and its circuit breaker is not tripped.
Inspect the connection
With power off, check the power connection between the oven and the hood is secure.
Test the supply
Measure the hood supply voltage with a multimeter to confirm power is present.
Service the hood board
If power is present but the hood does not run, have the hood power board checked.
When to call a professional
WC06 affects the hood accessory. Checking the supply may be straightforward, but testing the hood power connection and board involves mains-voltage work for a qualified Unox technician if power is present yet the hood stays off.
