Troubleshooting for a neutral break

When a vacuum was plugged in and turned on into a gfi plug it immediately blew. That gfi plug is fed from another bathroom upstairs and that plug was also out. The reset button will not work on either plug. It caused all the lights in bath/closet and second bath and office upstairs to go out. Replaced both gfi plugs and nothing works?? Any suggestions? We checked the neutral at the box and all the breakers seem to be fine.

Welcome to the forums! Be sure you first, turn the breaker completely off and back on again. A tripped breaker may not appear to be tripped sometimes. Having two GFCIs on one circuit can cause nuisance trips. Can you determine the circuit on which these receptacles operate? If so, de-energize the circuit by turning the breaker off. You can, now, remove all your receptacles on that circuit and determine if you actually have a missing neutral or other problems. If any of your receptacles have the wires stabbed into the back of them, remove the wires and attach them to the screws. Stab backs can cause the problems you are encountering.

Next, you need to find the direction of travel of this circuit and protect it at it's first receptacle with a GFCI. Then connect the other wires to the "LOAD" side of the GFCI to protect the remaining receptacles, eliminating the need for the second GFCI in that same run.
