I understand what a solid red or blinking red light means, but there's no documentation for it flashing once and turning off. I have it attached to a light switch, and each time I cycle the power off and back on, the light will flash red once. What does this mean? I have a receptacle tester plugged in, but it never lights up for even a split second. Pressing the test and reset buttons does nothing.

  • Did you replace a plain outlet that had a switched side to it? Did you replace the wires in the same pattern as you found them? Jan 9, 2019 at 2:03
  • What make and model is the GFCI? And yes -- was the prior receptacle half-switched? Jan 9, 2019 at 2:14
