Sounds like the fan limit is bad

So if the fan limit is bad, where is it located and how do I fix it?

Where are the heat strips? Inside the electric furnace?
Expert:  Jason Hvac replied 6 years ago.

Sorry, yes you have to take the panel off where the power goes in, that is where you will find the heat strips and that is where the fan reley will sit. Be careful, this is 230 volts
