MS25041 Press-to-Test Issue

[John Collier]

I've got a standard MS25041 light that is becoming intermittent upon pressing to test and with it's associated switch ON indication. Thought i'd see if anyone has an easy fix/suggestions before removing from my panel. It works with just the right "wiggle" and side pressure.

Thanks!

Corrosion

Sounds like dirt/corrosion. Remove the bulb and clean the base or replace it. Also, use a Q-tip and acetone or alcohol to clean the innards.
