Carrier 58MXB - replace solenoid, fried my furnace?

[tns]

I replaced the solenoid valve to the humidifier. I neglected to turn the power off to the furnace. While replacing the solenoid, I may have touched the controlling wires together or to the duct - I saw a small spark at one point. Now the furnace does not operate at all. Any ideas on what I might look at? Thanks.

You probably blew the control fuse. At the furnace circuit board look for a 3 or 5 amp automotive type fuse plugged into the circuit board.

Simply replace the blown fuse.

I did find a fuse on the board that looks to be blown and shows open on my ohm meter. The fuse is purple and is only labeled "E". How do I know if this is a 3 amp or 5 amp fuse?

nevermind - I was holding it backwards. It's a 3, not an E. Two dumb moves in one morning.

That was the problem. Thank you very much.
