Weird problem, our electricity got turned off before that everything was fine, when our electric got turned back on our furnace refused to work, but the weird thing is, if we plug in a generator to it, the furnace works fine, the status light is red but if there is no generator hooked up to it it does not blink at all.

Also where is the fuse in the furnace could that be blown?

You best be checking for the proper voltage from your main panel to your furnace. If it runs off a generator then the furnace is OK and the electric service from your home panel has a problem somewhere.

What's main panel? Doesthat mean thermostat? That's on and everything

The electric panel is in your home. Just because the circuit breaker is turned on does not mean that electric from the house panel is getting to your furnace. Just because your electric got turned back on does not mean that there is not another problem with your electric system. You need to use an electric test meter and sound out the system to find the offending part or circuit that is causing the problem.
