Test the Outlet: Press the "Test" button on the GFCI outlet. It should trip, cutting off power. If it doesn't trip, the outlet is faulty and needs replacement. Reset the Outlet: If the outlet trips, press the "Reset" button. If it resets but trips again shortly after, there may be a ground fault in the circuit. Check for Moisture: Moisture can cause a GFCI outlet to trip. Ensure the area around the outlet is dry. Inspect Wiring Connections: Turn off the circuit breaker for the outlet. Carefully remove the outlet cover and inspect the wiring connections. Look for loose wires or corrosion. Tighten any loose connections. Replace the Outlet:If the problem persists, replace the GFCI outlet with a new one. Follow the manufacturer's instructions carefully. Ensure the power is off at the breaker before you begin.

Flickering Lights

Flickering lights in the bathroom can be annoying and indicate a more serious wiring problem. It could be a loose connection, a faulty bulb, or an issue with the wiring itself.

How to Fix It

Check the Bulb: Start with the simplest solution. Ensure the bulb is properly screwed in and that it's not nearing the end of its lifespan. Replace the bulb if necessary. Inspect the Light Fixture: Turn off the circuit breaker for the light fixture. Remove the fixture cover and inspect the wiring connections. Look for loose wires or corrosion. Tighten any loose connections. Check the Switch: A faulty light switch can also cause flickering lights. Test the switch with a multimeter to ensure it's functioning correctly. Replace the switch if necessary. Inspect Wiring: If the problem persists, there may be a problem with the wiring in the wall. This is best left to a qualified electrician.

Overloaded Circuits

Bathrooms often have multiple high-power appliances, such as hair dryers, curling irons, and electric heaters. Using too many of these appliances simultaneously can overload the circuit, causing the circuit breaker to trip.

How to Fix It
