Problems with furnace breaker

Everytime my furnace kicks on I will get a buzz out of my breaker box and I will lose power to my electrical outlets in my living room, garage, and I will lose power to my stove. So I replaced the breaker for the furnace and checked all the other breakers to make sure that there wasn't any more burnt up. Then this evening I was in the garage and when the furnace kicked on sparks shot out of the breaker. None of the breakers are warm or hot to the touch. The breaker didn't trip when this happened and I'm out of ideas. I appreciate any insights to this issue. Thanks

Are we to assume that this furnace is electric?

If you have large electric furance or heat pump with back up electric heat possiblty you may have a loose connetion.

This need to be address right away before something else will damage.

If it is main brekaer area best to stop right there and call in electrician they can able do this due the safety issue.

and many electric furance do draw a quite bit of current all it depending on size of unit itself.

Did you get a good look at the buss bars where the furnace breaker was attached? Many times a bad connection at the buss will burn up the breaker and the buss stabs it was clipped on to. Take a look, and if it looks damaged, you might have to move the breaker to another slot.

Are you sure the sparks came from the furnace breaker, though? From your comment about losing power to other things when you'd hear the arcing, I really think you have a loose connection at the main breaker, and should probably get an electrician to check it out.
