I am having a problem switching a switch/outlet combo to a GFCI/switch combo. The GFCI switch provides power to a bathroom fan and light that are not protected.
I have wired the GFCI/switch as shown in the photo and when I test the GFCI using the test/reset buttons, the GFCI works properly. When I test the outlet with Gardner Bender tester, I receive a "correct" indicator. However, when I press the Gardner Bender test button, I receive "hot/new rev" indication and the GFCI outlet does not trip. Suggestions?
