Test Interior GFCI
High voltage is present on this equipment. Serious injury or death to personnel may
result if safety precautions are not observed.
1. Locate the GFCI convenience outlet (1) under the sink (2).
2. Using a multimeter set to read at least 250VAC, check for power between each receptacle inlet (3).
There should be approximately 115VAC between the two receptacle inlets.
3. Use a multimeter set to read at least 250VAC to check for power at ground inlet (4). There should be
no power reading between either receptacle inlet (3) and the ground inlet. If power exists, turn main
breaker to OFF.
4. Press the TEST button on the GFCI, and repeat steps 2. and 3.
5. If the GFCI convenience outlet (1) passes steps 2., 3., and 4. successfully, no further testing is
required. If not, disconnect power and proceed to the next step.
6. Remove screws (5) from faceplate (6) and remove faceplate.
7. Remove two screws (7) securing outlet (1).
8. Pull outlet (1) out enough to provide access to wire connections.
9. Tag and disconnect wires (8), and remove outlet (1).
10. Use a multimeter set to read ohms (Ω) to test for continuity in each outlet (1). If no continuity exists
between poles (9), replace outlet. If continuity exists between any pole and ground, replace outlet.
11. Reconnect wires (8) as tagged.
12. Install outlet (1) and retain with screws (7).
13. Place faceplate (6) into position and retain with screw (5).
14. Reconnect power, and repeat steps 2., 3., and 4.
