What Does Monogram Range Hood Error Code E4 Mean?

Error code E4 on a Monogram range hood is a grease filter full alert. The hood’s filter monitoring system — which tracks cumulative run hours — has determined that the grease filters have reached their recommended cleaning or replacement interval. This is a maintenance reminder, not a hardware failure.

How to Clear E4

  1. Remove and clean the grease filters — Take out all mesh or baffle grease filters. Wash in hot soapy water or run through the dishwasher on a heavy cycle. Allow to dry fully before reinstalling.
  2. Reset the filter counter — After reinstalling clean filters, press and hold the designated filter reset button (check your model’s use and care guide — typically labeled “Filter Reset” or held for 3 seconds on the fan or light button). The E4 indicator will clear.

Maintenance Schedule

Monogram recommends cleaning range hood grease filters every 1–3 months depending on cooking frequency. Heavy use (daily high-heat cooking, wok cooking, frying) may require monthly cleaning. Clean filters maintain airflow efficiency, protect the blower motor, and prevent grease fires.
