Hi !
Welcome to IRV2! We're sure glad you joined the gang!
Can't imagine what you could have done to cause that, although it's just too much of a coincidence! It has to be getting 120VAC or the fan would not be running. Only other possibility would be the 12VDC fuse blown, but I wouldn't think the fan would run if that were the case. Try unplugging and replugging the flat telephone wires that go to the thermostat.
Keep her between the ditches!
Good luck, happy trails, and God bless!
