Possible causes
- No power feeding the device
- Ground fault
- Moisture at the outlet
- Failed GFCI device
- Downstream wiring issue
Safe checks before you call
- Press test and reset only if the device is dry and undamaged.
- Check whether another nearby GFCI has tripped.
- Stop using the outlet if it is wet, hot, buzzing, cracked or discolored.
Professional assessment: GFCI troubleshooting may involve upstream devices, downstream outlets and wiring that should be tested safely.
When it may be urgent
Call if the GFCI protects a bathroom, kitchen, garage, outdoor, pool or appliance circuit and will not reset.
FAQs
Can a GFCI fail completely?
Yes. GFCI devices can wear out, but the circuit should be checked so the replacement is safe.
Does water affect a GFCI?
Yes. Moisture can trip protection and may indicate an unsafe outdoor or wet-area condition.
What if an outdoor outlet stops working after rain?
Stop using the outlet and keep away from wet or damaged electrical equipment. Do not repeatedly reset protection or remove the cover. Ask an electrician to check the outlet, weather protection and connected wiring before using it again.
