Hood Filter Alarms

4.03.1

Baffle, Pre-Filter or Charcoal Filter Missing

If a Baffle Filter, Pre‐Filter, or Charcoal Filter is not in place, or possibly not positioned correctly, the red [FILTER
MISSING] light will turn ON. Power to appliances under the hood is turned OFF until the condition is corrected. No
audible alarm will sound.
• Hood fan will continue to run.
• Confirm that all Filters are in place. See Sections 4.02.3 • 4.02.5 •
4.02.9, Filter Installations.
• You may try removing and reinstalling filters, to ensure that all
are seated properly in guides and are pushed fully into the filter
compartment so that doors properly close. Each filter must also
actuate a proofing switch located in filter channels (charcoal &
pre‐filter switches are in the top of the compartment; baffle filter switches are located in the filter rack
underneath hood).
• If the condition persists, call for service.
4.03.2

Baffle, Pre-Filter or Charcoal Filter Clogged

If the airflow through hood is reduced to a level that is below the minimum required for effective capture of
cooking vapors, a clogged filter alarm will occur. A constant tone audible alarm will sound and power to appliances
under the hood is turned OFF until the condition is corrected. This alarm is most commonly caused by clogged pre‐
filters or charcoal filters, but other conditions can also be the cause.
• Hood fan will continue to run.
• Clean the baffle filters, Section 4.04.1, Baffle Filter Cleaning.
• Replace charcoal or pre‐filter with fresh new filters, Section 4.03.4, Pre‐Filter Maintenance and 4.03.5, Charcoal
Filter Maintenance.
• Inspect hood plenum to ensure that no obstructions exist.
• Check the hood exhaust outlet and be sure that nothing is obstructing it.
• Inspect both sides of the hood blower. Excessive accumulation of grease residue on the fan blades can reduce
airflow. Clean if blades if needed.
• If the condition persists, call for service.
