I have an outlet in my garage that is not GFCI. It has both line and load lines attached along with a ground wire. It works fine but when I plug in a tester and push the Test button, nothing happens (it should be part of a GFCI circuit so the fact that nothing happens means something appears to be wrong). So, I want to change this for a GFCI outlet. I installed the GFCI outlet and when I plug in the tester is shows "> 30 VAC" and "Open Gnd Neu" and the red light on the tester illuminates. I removed the outlet, reinstalled the old one and it works fine, except it doesn't respond to the GFCI test.
The reason I am replacing the outlet is because the inspector for our house said that the garage plugs should be on a GFCI circuit. I'm not sure why this particular outlet is not part of a GFCI circuit, but installing a GFCI outlet is not working.
Has anyone experienced this and/or knows why the new new GFCI outlet is failing? I tried two different new outlets and both produced the same error.
