How To: Check Your Fuses In Five Easy Steps


I'm taking a step back in time from our technology-driven culture. I have been, for the past two weeks, living like a pioneer. Ok, more like a part-time pioneer. My refrigerator decided to throw in the towel and call it quits three days before Easter. Before finally calling a technician for help, I tried the standard troubleshooting process, hoping it would provide resolution. 

Unfortunatelyit became clear the issue requiremore than an inexpensive quick fix. As it turns out, the source of my refrigerator's problems is the dreaded compressor – an issue that could only be seen by digging a little deeper.  

Whether you're working with a common household appliance or a sophisticated sequencer, you must identify the underlying problem before you can address its symptoms. When something is wrong with your sequencing equipmentthe issue may not be obviousWhether you realize it or not, everyday wear and tear causes damage to the fuse. And inevitably, it will blow at the most inopportune time. However, there is a quick assessment you can conduct to check your fuses 

Following this guide will help you quickly assess the problem while eliminating potential causes. Sotake several deep breaths, and let's get started:  

    1. First, be sure to turn off the instrument's power.  
    2. Then, if you are working on the 3xxx series, remove the front cover.  Screen Shot 2018-04-18 at 4.38.06 PM

5. Verify the condition of the 3.2 amp fuse on position C-14. If you observe the fuse is discolored or black, that is your starting point for solving the instrument’s problem.
