So the g.f. and I are chipping in on a newly remodeled investment house
in her city, 300 miles from me. Home inspector sent a report that
included a notation that the outlet intended for the refrigerator is
giving an odd indication on the 3-LED tester: All three lights
illuminate.

Any speculation on what could cause this unlisted and presumably
improbable test result?

Each terminal of an outlet can be hot, open, or grounded. That makes 27
possible combinations.

With the tester I know you don't get all three lights unless the hot
terminal is grounded and neither other terminal is grounded. Both the
neutral and ground may be hot, or one may be open.
