Checklist for Dimmer Switch Replacement
Electrical Question: I’m trying to replace a three way dimmer switch with the same model. At first the light would not light until the switches were in a certain position. I replaced 3 way with a non dimmer type and the lights work all positions.
I’m not sure what is wrong as it worked before with the dimmer other switch.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
