First, we had a 15 amp two pole "d square" circuit breaker that tripped, the bottom swich will not reset. We replaced it with a 20 amp two pole "d square" circuit breaker and the bottom switch would not reset.

Now the top switch still works for our garge door opener (we can operate the garage door with no problems). But the bottom works the outlets in my daughter bedroom. We have unplugged everything, and still nothing.

We removed her ceiling lamp, and cked the outlet wires (nothing noticeable there). We are planned on replacing all the outlets and light switches.

But I was wondering what else we need to try or look for.

NEVER REPLACE A BREAKER WITH A LARGER SIZE.

THEY ARE SIZED TO THE APPLICATION AND WIRE SIZE. USING A LARGE BREAKER CAN ALLOW THE WIRES TO OVERHEAT AND CAN LEAD TO A FIRE.

What you describe is a tandem breaker, two independent breakers in the space of a standard breaker.

A 2 pole breaker is twice the size of normal breaker is used for 240 volt loads such as an airconditioner or electric stove.

Save the money for replacing the receptacles and switches and call an electrican.

There is only 1 in a 10,000,000 chance that the problem is in switch or receptacle. Yes, they fail, but for a short they would have to be broken in 2.

But have you check adjacent rooms.

It would be unlikely that the circuit only feeds on room.

yes, we cked the other rooms. the breaker only covers the one bedroom and garage door.

Lowe's advised to use the 20 amp instead.

thanks for the help.

What you describe sounds like a multiwire circuit, where a double pole breaker protects two 120V circuits that share a neutral wire. If one half of this breaker will not reset, that means you have a dead short somewhere that must be fixed. This will require some troubleshooting skills the average DIYer may not possess, so you may want to call in an electrician.

And to add to what Bill said: NEVER LISTEN TO ADVICE FROM A L*WES OR HD EMPLOYEE!
