Samsung Ventilation / Exhaust Performance Issue

Microwave fan runs but there is little or no suction from the vent (OTR models).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect damper installation, Blocked ductwork, Grease-clogged filters, Weak or damaged vent fan blade

Safety: Turn off power at the breaker before working near the fan or duct.

Check filters: Remove and clean grease filters. Replace charcoal filters if used in recirculating mode.
Inspect damper: Check the damper flap at the top or back of the microwave to ensure it opens freely and is not installed backwards.
Check duct: Inspect the external vent hood for obstructions such as bird nests or debris.
Service fan: If airflow is still weak, the vent fan motor or fan blade may be damaged and should be inspected and replaced by a technician.
