White Rogers model 50a50-215 Controller
« on: October 09, 2014, 10:03:47 AM »

Clare Furnace Model # HEMI 110-8D.    Controller : White Rogers Model50a50-215
My furnace does not start up. The fuse on the 24volt transformer blows after about 5 seconds. There's no code flashing on the controller. Could this mean the controller is bad? What could cause the overload condition for the transformer?

I'm leaning toward it being the controller.  It's the only 24 volt component.  If it was a short in your low voltage wiring, the fuse would blow instantly.
