Dryer Not Heating? Try Replacing the Hi-Limit Fuse (DIY)

Introduction

What good is a clothes dryer if it doesn't heat up? Get your dryer heating again for less than $25!

Each year, thousands of dryers end up in landfills because they no longer heat up. Often, though, all that’s needed to get them working again is replacing an inexpensive part called the hi-limit fuse. Here’s the thing… dryer manufacturers don’t tell consumers how to do it.

Hi-limit fuses (AKA thermal fuses or hi-limit thermostats) are safety devices that help prevent the dryer from overheating and causing a fire. Your dryer can have up to three of these. They fail because the dryer can’t exhaust the hot, moist air inside. That’s usually because of a clogged dryer vent tube, or one with too many bends.

Many people pay a professional to come in and fix the dryer for around $200, or replace the whole dryer for around $800. Instead, I’ll show you how to replace or reset the hi-limit fuse and get your dryer heating again.

Many brands, like Bosch, LG, Samsung and Miele, offer hi-limit fuses that can be reset by pushing a button instead of replacing them. You’ll find your hi-limit fuses behind the top panel, back panel or lower front panel.

Pro tip: Clear your dryer vent tube before replacing the hi-limit fuse. If you don’t, you’ll blow the fuse.
