What Does Monogram Range Hood Error Code E1 Mean?

Error code E1 on a Monogram range hood indicates a blower motor speed fault. The control board monitors the blower motor’s rotational speed via a feedback signal. E1 appears when the actual motor speed does not match the commanded speed — the motor is running too slowly, inconsistently, or not at all.

Common Causes

  • Failed blower motor — The motor has burned out or its bearings have worn, causing erratic or zero RPM feedback.
  • Grease-clogged impeller — Heavy grease accumulation has caused the fan impeller to become unbalanced or restricted.
  • Wiring fault — A loose or broken wire between the motor and the control board.
  • Speed control board fault — The triac or speed controller on the board has failed.

How to Troubleshoot

  1. Clean the grease filters — Remove and wash all grease filters. A heavily loaded filter or grease-soaked impeller significantly restricts airflow and strains the motor.
  2. Hard reset — Switch the hood off at the circuit breaker for 60 seconds, then restore power.
  3. Test all speed settings — Run the hood at each speed setting and note which, if any, operate normally.
