None Range Hood: not operating

Professional Repair Guide

What is this symptom?

If your range hood is not operating, you may notice that the fan fails to start and no lights illuminate when the controls are activated. This often indicates underlying issues such as power supply problems, a locked control panel, or internal component failures. Understanding these symptoms can help you diagnose the problem effectively.

Urgency: Medium

Possible Causes

Power supply issues (breaker, plug, internal switch)

How to Identify: No lights or fan activation; other appliances may also be without power; check breaker panel and hood internal power switches.

Part: Electrical supply / internal switch

Control lock or switch lock engaged

How to Identify: Pressing buttons produces beeps without activation; control lock indicator may light.

Part: Control panel / switch

Blown internal fuse or thermal cutoff

How to Identify: No response from controls despite correct power; continuity test with multimeter shows open circuit at fuse.

Part: Internal fuse / thermal protector

Motor failure or seized fan due to wear/contamination

How to Identify: Hood remains silent or may hum slightly; fan does not spin; age of unit >10 years suggests motor degradation.

Part: Blower motor or fan assembly
