Q: I went to use my hairdryer in the bathroom, but I discovered some of the outlets have stopped working. My GFCI test button won’t push in when I try to reset it, but nothing has tripped in the breaker box, and the hairdryer works when I plug it into outlets down the hall. Why won’t my GFCI reset?
A : Ground error electrical circuit interrupters , or GFCIs , are wall socket design to shut off when they sense a ground fault or scant in electricity . When a GFCI mercantile establishment senses an overburden or surge in electricity , it will at once trip , triggering the breakers to cut off the electric electric current to minimize the risk of exposure of electrocution . For safety cause , construction codes postulate that a GFCI outlet be used near any water supply source or moisture due to the increase peril of an convenience shorting .
When a GFCI wo n’t reset , it requires a mo of testing to figure out what ’s pass away on . If a GFCI electric outlet is n’t working , trigger such as the presence of moisture or dust , bad electrical connexion , or something more serious can cause the outlet to activate . Luckily , there are several thing homeowner can do to try and key the job before calling in an expert lineman .
1. Check if other outlets in the room are working.
Because multiple outlet in a room can be connected to the same circuit , a non - functioning GFCI issue could cause issues with nearby outlet as well . understand how the internal wiring is laid out in a house will make it easy for a householder to nail the government issue and determine if it ’s a GFCI trouble or something else that needs to be address by a professional .

If the outlets are only affect in the one elbow room , there ’s a good chance the GFCI mercantile establishment caused the problem . Homeowners will want to also test multiple appliances to see that it is , in fact , an issue with the GFCI outlet not working and not an matter with the appliance itself .
2. Try toggling the test and reset buttons.
Each GFCI outlet has a trial run and reset clitoris , often labeled bootleg for the test clitoris and violent for reset . These buttons can test the power running through the GFCI circuit and readjust the outlets .
To properlytest and reset the GFCI , homeowners will require to unplug all widget share the same circuit as the GFCI and then press the reset button on the GFCI outlet . If they hear a click once the button is pressed , they can try plugging in the gadget , as the outlet should be functioning again .
However , if the release keep on to spark once it ’s been reset , it may be getting overloaded by the phone number of appliance plugged into it around the elbow room . To test if it ’s the number of machine being plugged in , homeowner can use a process of elimination to fancy out which appliance is causing the issue by plugging in one appliance at a time until the GFCI outlet trips again .

3. Use a circuit tester to see if power is coming through.
In most young homes today , updated GFCI sales outlet have a self - testing feature in which green and flushed LED indicator show whether an outlet is operating correctly or if it is faulty and needs to be interchange . Many householder will find that they have older GFCI outlets installed that postulate to be manually try out . fortunately , examination outlets can be an inexpensive job with life - saving benefits .

Circuit breaker finders are instrument that can interpret and display how strong of an electrical current each wall plug is receiving and can mold if an outlet is functioning properly . householder will want to essay all nearby exit to see if just one outlet is being affected or if the intact room ’s power is being affected .
4. Look for any tripped breakers.
A GFCI outlet wo n’t run if a breaker has turn on or if a fuse has blown . Homeowners can check the main electric gore to see if a foul up fuse causes the take and if so , supplant the fusee and reset the GFCI electrical outlet . Otherwise , they ’ll require to tick to see if the ledgeman for the corresponding way has trigger .
To see if a surf has turn on , homeowner can count at the buttons inside the breaker box . The breaker electrical switch should either be flip to “ off ” or “ on . However , if a transposition is located in the midway position , that intend it has tripped and ask to be reset . To reset it , householder will first flip it to the “ off ” position , then switch it to the “ on ” situation . They ’ll want to be sure to readjust the GFCI outlet as well . If the breaker get off again after this fix , the topic could be ashort circuitwhich can be serious and should be address by a accredited specialist .
5. If there’s moisture, try drying the outlet thoroughly with a hairdryer plugged into another outlet.
If a GFCI outlet sense that there is moisture present in or near the outlet , it will trigger off as a means to forestall electrocution . When it set off , it shuts off and stops electrical energy through the outlet as a safety measure . If moisture happens to be present in the retail store , it ’s important that homeowners to remove all traces of it before resetting the GFCI and attempting to plug anything into it .
To remove wet , householder can try plugging a hairdryer into a different outlet nearby and get it at the GFCI vent that has moisture present . They ’ll want to grant the hairdryer to thoroughly remove the wet from the area before continuing , as any comportment will cause the GFCI reset to be unsuccessful .

From there , the outlet can be pulled a little way out of the wall for easier access .
Once the wire have been exposed , householder will require to mildly towboat on each one to confirm if they are firmly fix underneath the screws . If a wire is n’t securely fastened , it will need to be cut and reattached securely underneath the screw to ensure it ’s well connected . As a rule of thumb , inglorious telegram should be attach to gold shag , and livid wire should attach to silverish screws , and the screw should securely fasten each telegram on the side of the vent .
Call an electrician if the issue doesn’t seem to be a quick fix.
Sometimes a seemingly wrong GFCI vent can indicate a bigger problem that should be addressed by a professional . Inexperienced householder should not execute extensive electric repairs on their own because it can posture a life-threatening risk of injury , such as electrocution , and an increased risk of property damage .
If the issue seems to be more invading than a quick DIY repair , householder will want to contact a licensed linesman to have them take a spirit . Depending on localisation , electricians costaround $ 50 to $ 100 per time of day or around $ 300 per undertaking and have specialized , gamy - tech equipment that can assist observe problem homeowner may not have be intimate about .
