We were running it off 3 bulbs since one had burned out, gently. I push the control to go all the way to 3rd level, 50 watt brightness, and another bulb blows, bright flash, the whole unit shuts down, silence.

I go flip the breaker and it comes back on, fan works fine, but now the lights won't go off. Control module now has a shorted light circuit, fused, on permanently, according to the Broan tech I spoke with. No fixing the control module.

Now, I'm having trouble finding what the GU10 +C base of the bulbs is, exactly. I find only one reference to a -C base having a built in fuse so that a violent blowout like that won't trip the breaker. Obviously this did not happen for me and a simple bulb burning out has now turned into a terrifying possibility of a $100 control module if/everytime it shorts again like that.

So, can someone clarify is there a GU10-C that would have saved my control unit, as opposed to just picking up some regular GU10 Sylvania or GE's at the store?

Thanks
