How to Fix Broan-NuTone Range Hood Error Code E01
- 1
Clean the grease filters and blower wheel
Remove the grease filters (most Broan filters pull straight down or tilt out). Wash in hot soapy water or the dishwasher. If accessible, also clean the blower wheel — grease accumulation on the blades causes imbalance that makes the motor work harder.
- 2
Check the exhaust duct
Go to where the duct exits the house and confirm the damper flap opens freely. Check the full duct run for kinks, disconnected sections, or blockages — a bird or wasp nest at the termination cap is a common culprit. Duct should be as short and straight as possible with no 90-degree elbows close to the hood.
- 3
Power cycle the hood
Turn off the circuit breaker for 15 minutes to reset the motor overload. If the underlying cause is resolved (duct clear, blower clean), the motor will run normally.
- 4
Replace the blower motor
If the motor bearing has seized or the motor is drawing excess current even with clean blades and clear duct, replace the motor/blower assembly.
