🔍 Why This Happens
Root cause analysis for your range hood's fan not working
The range hood fan motor in your range hood degrades through repeated high-temperature cycles that stress the material. Each heating cycle causes thermal expansion and contraction — over time, the element fatigues and develops micro-fractures or the thermal safety device trips permanently. This is one of the most common failure modes for this appliance type, especially in units over 5 years old.

🛡️ Prevention Tips
How to prevent your range hood's fan not working from happening again after this repair.
Clean or replace the grease filters every 1-3 months depending on cooking frequency. Clogged filters reduce airflow and strain the fan motor.
Wipe down the interior and fan blades quarterly to prevent grease buildup that can damage the motor and create a fire hazard.
If vented to the outside, have the ductwork inspected annually for grease accumulation and blockages.
Run the fan for 5-10 minutes after cooking to clear residual moisture and grease from the ductwork.
If you're replacing a thermal component, consider replacing related safety devices at the same time. The range hood fan motor likely stressed surrounding parts.
