None Exhaust Fan: not working

Professional Repair Guide

What is this symptom?

Is your exhaust fan not working? You may notice that the fan blades aren't spinning, there's no airflow, or you hear a humming sound without any movement. This issue can stem from various causes, including electrical problems, obstructions, or lubrication issues. Understanding these factors can help you troubleshoot effectively.

Urgency: Medium

Possible Causes

Power supply or electrical connection issue

How to Identify: Fan does not respond at all when switched on, no sound; check if other devices on same circuit work and inspect switch and breaker.

Part: Wiring, switch, circuit breaker

Faulty on/off switch or control

How to Identify: Switch feels loose or unresponsive, continuity test with multimeter fails.

Part: Control switch

Obstruction or blade blockage

How to Identify: Blade won’t turn freely by hand due to debris or dust build‑up.

Part: Fan blades/impeller

Insufficient lubrication causing stuck bearings
