can an inducer switch fault and rollout switch fault cause a fuse to blow. LED shows 6 and 7 flashes on carrier rooftop. gas heat. Fuses blew yesterday, today 1 blew. I followed wires back from fuses,( not main disconnect fuses, the 3amp fuses from primary of trans former) going to inducer motor. I start up unit, and jump r to w to test, motor doesnt start but LED shows the 2 faults. If there faults ok, but why would the fuses blow. Would these be related, I started up in cool mode and all was good.
