120v Point-2-Point™ Voltage Pen Troubleshooting Cheat Sheet

Using a voltage pen with the process described in this article, you can more definitively determine where a failure is in a circuit, as compared to a static method of “ohming out” components. THIS BLOG IS INTENDED FOR APPLIANCE TECHNICIANS ONLY. ALWAYS USE APPROPRIATE SAFETY PRECAUTIONS WHEN WORKING WITH ELECTRICITY.

Brute Force Voltage Pen Diagnostics

This sequential voltage-pen troubleshooting sequence reveals the failed portion of a 120v circuit by identifying the voltage transition indicative of an open component. Such a systematic approach to finding failed components is a more definitive method than “ohming” parts out. Below is the point-to-point voltage pen testing methodology for diagnosing 120v appliances when your “Subject Load” is not energized:
