A GFCI that trips with no load is detecting a ground fault. Common causes include moisture in the box, a downstream wiring fault on the same circuit, a worn or failed GFCI device, or incorrect line/load wiring. GFCIs trip when they sense current leaking on an unintended path to protect you from shock.
Quick checks:
- Press Reset and try again.
- Dry the area if in a kitchen, bath, garage, or outdoors.
- Unplug everything on that circuit and retest. If it still trips, call a licensed electrician.

You can replace a light switch only if the power is fully off and you’re confident with basic wiring. If the switch is buzzing, warm, scorched, or tripping a breaker, it likely needs professional repair. Cardinal Heating & Air Conditioning repairs and replaces standard and dimmer switches and troubleshoots faulty or sparking switches in Madison and Sun Prairie.
Quick checks:
- Stop immediately if the switch is warm, buzzing, or sparking.
- Turn off the correct breaker before any work.
- If issues persist after replacement, call a licensed electrician.

Cardinal installs and repairs GFCI, AFCI, USB, and standard outlets, and fixes dead or sparking receptacles. GFCIs trip fast to stop shock. AFCIs help prevent fires. For code-conscious upgrades in Madison and Fitchburg, our licensed, background-checked techs handle it.
Quick checks:
- Shut off the breaker and verify power is off.
- Match wiring and outlet rating.
- Test GFCI after install.

You can install a GFCI yourself, but we recommend a licensed electrician for safe, code‑compliant results. GFCI outlets protect against electric shock by cutting power faster than breakers when they sense an imbalance. Incorrect installation can leave the receptacle unprotected. We install and replace GFCI outlets and GFCI with switch, and we troubleshoot GFCI issues in Madison, Fitchburg, and nearby areas. 24‑hour emergency electrical service is available in some locations.
