I need a bit of advice from someone in the electrical trade. We have a hair dryer with a GFIC (Ground fault interruption) plug. Last week when I was testing the plug, the reset button popped out as expected but refused to go back in. However, the dryer still works. How much do I need to worry? Can I replace the plug myself? Are they available to the layman? Should I restrict using it to a GFCI receptacle? Thanks for the non-RR advice.
