What are the common reasons a replaced GFCI doesn’t work?

A replaced GFCI may not work due to several common issues. First, it’s possible that the wiring was not connected properly during the replacement. If the hot, neutral, or ground wires are miswired or disconnected, the GFCI will not function as intended. It’s crucial to double-check that all wires are securely attached and in the correct order. Additionally, ensure that the wires are stripped properly to make solid contact with the GFCI terminals.

Another potential issue could be with the circuit itself. If there’s an overload or a fault elsewhere in the circuit, it may prevent the GFCI from operating correctly, even if it has been replaced. Furthermore, the electrical supply to the GFCI could be interrupted due to a tripped breaker or a blown fuse that needs attention. Checking these elements can help pinpoint the problem.

How can I troubleshoot a non-working GFCI?

To troubleshoot a non-working GFCI, start by checking the power supply. Confirm that the circuit breaker hasn’t tripped and that all fuses are intact. If the breaker has tripped, reset it and see if the GFCI resets as well. If the circuit appears functional but the GFCI still does not work, inspect the reset button on the GFCI itself for any signs of damage or malfunction.

Next, consider testing the outlet with a multimeter. Set the multimeter to measure voltage and check for power at the input terminals of the GFCI.
