Introduction

This guide will show you how to fix a wobbly Westinghouse 12" High Velocity Fan. Oftentimes, the set screws can become loose on the impeller assembly. This can lead to unwanted wobbling but also puts the fan under the danger of coming apart, so it is best to address the issue sooner rather than later.
Luckily, this guide only requires a screwdriver and walks you through every single step on how to carefully disassemble your fan and tighten the set screws to ensure your fan runs as good as new.

Preparation is key when it comes to a smooth repair process. It is important to have a well-lit environment and a sturdy surface, such as a table. It may help to place a cloth underneath the fan to collect any debris that may come off the grille or the blades.
