I've looked at 3 furnaces plugged into combination switch/outlets that have indicator lights, but no GFCI switches. On just one switch, the indicator light is flickering unevenly. Is it trying to tell me something?

    Is the indicator light neon? if so, these can flicker normally. – Chenmunka Oct 18 '17 at 15:11

    Photo needed. Please edit your question to add a photo. Consider also, takng the plate off of the switch/outlet so we can see the full device and some of the wiring. – Billy C. Oct 18 '17 at 16:12
