Customer Questions and Answers for Stirrer Motor (Service Kit) by Whirlpool

This is the stirrer motor assembly that drives the metal stirrer in the microwave's waveguide. A working stirrer helps distribute microwave energy more evenly, reducing hot and cold spots for consistent heating.

• Rotates the mode stirrer to spread RF energy inside the cavity
• Symptoms of a failing motor can include uneven heating, cold spots, buzzing or grinding from the waveguide area, or the stirrer not turning
• May restore even cooking performance when the original motor is worn or seized

• Unplug the appliance before servicing; high-voltage components in microwaves can retain a dangerous charge
• Remove the grill/cover and access panel to reach the stirrer motor location
• Transfer any mounting hardware from the original part if not supplied
• Ensure the stirrer blade or coupler is correctly seated and turns freely before reassembly
