So far, so good!

Update:

I just made it to the electrical store and purchased a new breaker. Crossing my chilled little fingers!

I have an electric coleman EB15B, 16 yrs. old. The breaker keeps tripping. Ventilation will stay on but when I switch it to heat it trips in 5 minutes or so. I replaced both heating elements and it still does the exact same thing. I'm in Ohio and I'm freezing. Please let me know if you have any idea...
