When i initially finished my work and went to flip the swiches back on the electric room was in the dark. As i flipped them you could see a blue spark as they went on.
Are you talking about the breakers? Where did you see the spark come from?
When you swapped the "light switches and plugs" are you sure you put everything back the way it was?
Also, they are called receptacles or outlets, not plugs.
Your problems is one of the flollowing
1- You didn't reconnect something correctly or inadvertanly disconnected something in one of the boxes you were working in.
2- You have a bad breaker(s)
3- You have a short preventing your breaker from staying on (see#1)
I would assume that your heat and your range are on different circuits. It would be extremely unlikely that you had 2 breakers go bad. Most likely you either didn't reconnect something correctly, didn't use the same type of outlet or switch or disturbed another connection in the box you were working on.
Why were you replacing outlets and switches in the first place?
Do you know what old outlets came from which locations? Outlets can look the same from the front yet be a little different on the back. Some have tabs that are removed if an outlet has two circuits passing through it or 1/2 switched. Its a common mistake to not remove that tab. Its unlikely thats related to your problem but could be, who knows.
Anyway, this problem may be very had to troubleshoot on a forum. May be time to call in a pro.
