Elec Furnace won't shut off

I have a Frazier-Johnson elec. unit...troublefree for 12 years..but it will not shut off today. Fan continues to blow, heat continues to flow. Lowered tstat to 50 degrees...still will not quit. Only way to shut it off is the breaker switch on the unit. What might be the problem? Thanks.

faulty t-stat will make this happen
1.check the stat and make sure it is working fine

if so than it could be something in the t stat wiring or in the control system

Lightbulb furnace

If you have checked the tstat Taken the wires off and the wires to it and they are ok Take you hand and hit the furnace hard on the side of it.this could stop it .If so you have a relay that sticks. ED
