I recently bought an older home. I switched out the old receptacle in our spare bedroom to be able to accomada
te a three prong plug. I then plugged in a small ac unit which worked fine for a few days then all of a sudden no juice to it. This was after nothing connected to it being on for at least a day. The breaker is fine, everything else wired to it works. Also, I changed out the receptacle just in case….still no juice. What could cause power to all of a sudden not flow to the receptacle? There is no juice at all going to it, and I have no idea. Thank you for any input.
Make sure you are looking at the correct breaker to start. If the breaker is working, then start checking any GFI outlets that may be up stream of the outlet in question. Check nearby outlets for power. If everything checks out fine, you have a loose connection in the circuit. Look in adjoining boxes, junction and outlet to see if there aren’t loose wires in a wire nut or coming out of a pass-through outlet up stream. A high resistance ground, also called a tech ticker and power detector, the item that lights up near a powered wire, will be useful in tracing where there is and is not power.
