Snydergeneral model 50A50-110 no power, no response

Furnace was working fine. I replaced thermostat with digital one. I hooked up blue wire I don't think I was supposed to. Hooked up the other green, white, red, and yellow. Furnace doesn't come on now. Checked for 110 voltage. No diagnostic light at all. Is there a reset, lockout switch, fuse, or other safety device. Any suggestions? Thanks.

check for a low voltage fuse on the control board or in that vicinity.

If the furnace does not have a low voltage fuse or low voltage circuit breaker you will probably need to replace the 24VAC transformer.

Do you have a meter?
