My bedroom & bathroom are on same breaker switch and i have no power going to either. I tried to reset switch by going off then on , i turned main power switch off then back on, i replaced the switch , with all that done the switch continues to stay in trip mode. The switch is a Square D HOM .
The reason why the breaker stays tripped is a result of a direct short. Unplug every electrical device plugged into an outlet in both rooms and try the breaker. If it stays on, individually start plugging in each device until the breaker trips, that is the defective device. If the breaker stays tripped, start checking wall outlets for short circuits with an ohm meter. If you did not find a short, check your hard wired lamps and appliances for shorts. If you did not find any shorts the only other problem is a shorted pair of wires in the wall or ceiling. You will need to disconnect any hard wired lamps and appliances and check for shorts between individual pairs of hot (black) and neutral (white) then hot and ground. I have a short circuit finder, but you do not need one because the technology is not perfect and you may have to manually check for shorts with a meter anyway which never lies.
Hello; Unplug everything, then try resetting GFI. iF IT DOES NOT RESET, YOU KNOW IT'S NOT AN APPLIANCE.ccHECK UNDER THE KITCHEN SINK MAKING SURE THE DISPOSAL OUTLET ISN'T WET. SINK AND PLUMBING LEAKS LOVE THAT POORLY PLACED OUTLET. tHEN CHK ANY OUTSIDE OUTLETSFOR EXPOSURE. aGAIN, IF NOTHING IS FOUND ATTEMPT RESET. iF IT RAINED RECENTLY IN YOUR AREA, LOOK FOR SIGNS OF AN EXTERIOR OUTLET BOXES HOLDING WATER.
gOOD lUCK AND BE PATIENT, iT JUST HAS TO BE LOCATED.

You said you "replaced the switch". Do you mean you replaced the breaker and the new breaker will not go on? If this is the case, then you have a short circuit in the wiring, or in the bedroom or bathroom, and the breaker is doing it's job. Have any recent changes been made in the outlets, switches, or fixtures in these rooms? Any recent nails put into walls? If not, try unplugging everything in those two rooms. You will have to find the fault by a process of elimination.
I also found this description of the HOM type breaker. It may give you some clues---
Single Pole Arc Fault HOM Designed to detect arcs that are caused by damaged - aged or improperly used wires or cords and to disconnect the power.Arc faults can not be detected by standard circuit breakers and fuses.Square D Arc-D-tect AFCI3 will fit into existing Square D loadcenters.
