I was moving our thermostat, now heater is not working, LED blinks 2 times slow 4 times fast, panel says it's an open circuit at the 24 volt fuse, or a short. Could I have blown the fuse moving the thermostat? If so where is it located ? I'd like to try and do this myself,Being Thanksgiving, where can I get the Part? Home Depot?

Thanks
Happy Thanksgiving
