I have no power running into my master bedroom the whole room and all the outlets in it are out. The attached bathroom and closet have power and the rest of the house as well. I went to the breaker box and the Master bedroom switch was in the on position...
I cut the switch off and then on again a few times
I turned off the main switch in the breaker box, waited awhile, then cut all the switches off, cut the main one back on and then all the switches one by one.
Bedroom still out.

HELP!!

Please and thank you

Most likely there is a loose connection, usually at the last working receptacle or the first nonworking receptacle on the circuit. This requires the devices to be pulled out looking for the bad connection and reconnect the wire .

If your not knowledgeable working on wiring, an electrician will need to be called in .

Sounds like you have a broken or loose wire in an outlet that feeds through to the other outlets. Pull the outlets out and look for a loose black or white wire. If they are backwired, make sure the wires are seated properly. If everything looks right, you may have a bad breaker or a loose wire in the breaker box. Turn off the main breaker, CAREFULLY remove the front and look for a loose wire on the breaker for the room. If that is tight, test the breaker with an ohmeter, it should show 0 Ohms in the on position. If the breaker is OK, you have a loose or broken wire somewhere in the feed to the room.
