JennAir Oven: not working blower motor

Professional Repair Guide

What is this symptom?

Is your JennAir oven's blower motor not functioning? This can lead to uneven baking and temperature issues, especially during convection cycles. If the fan blades aren't spinning, it may indicate a faulty blower motor or control board. Understanding the causes and solutions can help restore proper air circulation and baking performance.

Possible Causes

Faulty blower/convection fan motor

How to Identify: Fan blades do not spin freely by hand; motor fails continuity test with multimeter.

Part: Blower/convection fan motor

Faulty control board not sending power to motor

How to Identify: Other oven functions also failing or intermittent; fan receives power but motor does not start; visual damage on control board.

Part: Main control board (electronic control)
