Broan-NuTone Range Hood Error Code E01

What Does Error Code E01 Mean on a Broan-NuTone Range Hood?

Fan motor overload — motor drawing excess current.

The fan motor has tripped its overload protection by drawing more current than the rated limit. This is usually caused by a worn motor bearing, a buildup of grease on the blower wheel, or a blocked exhaust duct restricting airflow.

What Causes Error Code E01?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1. 1
   Grease buildup on blower wheel causing imbalance and drag 45% of cases
2. 2
   Blocked or kinked exhaust duct increasing static pressure 30% of cases
3. 3
   Fan motor bearing worn or seized 20% of cases
4. 4
   Control board motor driver failure 5% of cases

How to Fix Broan-NuTone Range Hood Error Code E01

1. 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. 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. 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. 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.
