Electricity Problems
 
I just started having a problem with my electricity. I recently bought a house and when the furnace comes on it stays on for about five minutes and then blows the fuse, which in turn shuts off the power to most of the house. I also just installed a garage door opener but i doubt that is the problem. The furnace is relatively new. I have tried turning off the power to the furnace and this problem still persists. The power will stay on for about 10 minutes and then shuts off. Anyone have any ideas what it could be?

thanks!

Is the whole house losing power or just the furnace circuit? And how are you turning the power back on? If the power is coming back on by itself it sounds like you have a high resistance connection that gets hot and opens the circuit. Then after it cools it makes contact again and poof its back on.
Sounds like you need a professional electrician unless you can provide more information.

It is only parts of the house that lose power. Like the outside lights, the doorbell and a couple of bedrooms. When this happens i reset the breaker, both the main and the furnace breaker. Then power is restored for about five minutes and blows again. I have tried leaving the furnace breaker off and resetting things but the outside lights and 2 of the bedrooms lights go off on their own.

Are you saying that only PARTS of the house lose power when the main breaker trips?

Its not that the main breaker trips i just reset the main breaker once the power goes out in parts of the house. The odd thing is, is that no single breaker is tripped when the power goes out.

So, neither the main breaker or furnace breaker are tripping? When a breaker trips, sometimes it will look like it isn't tripped. Next time it happens, if you can push the breaker "on" without pushing it "off" first, then it has tripped. But, when it does trip, you will ahve to reset it by switching it off first, then on.

As for troubleshooting WHY this is happening, I can't contribute. The pros should be able to help you, though.

The two statements are contradictory. Either you have a breaker tripping or you don't.

If a breaker is tripping after 10 minutes then the branch circuit is likely overloaded.

If no breaker is tripping then I'm inclined to agree with JV that you have a loose connection that is opening the circuit. It could be the grounded leg (white) or a the hot wire . A voltage test at a non-working receptacle, hot to ground would tell us a lot.

Do you have to reset the main to get things back on? Or do you just do it for giggles?

If it is the only way to restore power, you have a loose wire on the main and the overheating damaged the breaker. Look for burn back on the insulation.

I think you need an electrician. A bad connection could cause a fire.
