Model 7975-856 Coleman presidential 3 won't stop blowing
One thing you can try is power cycling the unit. Off at the breaker/power switch for 15 min then back on, sometimes this will clean the bios and get it back online. If that does not work the next thing to try is to clean off the flame sensor. Thats a little metal piece that is in the path of the flame.

Do electric furnaces lose efficiency over time?
Not really, they don't lose efficiency. Electric heating is notoriously expensive. To reduce your bill make sure your home is well insulated especially the roof space and make sure there are no drafts from doors and windows and floor edges.
