I bought a Nest thermostat. I tried putting it in today

Customer Question

I bought a Nest thermostat. I tried putting it in today without turning any power off. Now, even after putting the old thermostat back on, I cannot get the air to turn back on. O am looking at the guts of my Lennox 193UH series now
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: 6 degrees below what the room temp is and breakers are on
JA: Do you plan on doing the work yourself?
Customer: So far, yes
JA: Anything else we should know to help you best?
Customer: Nope
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.

Hi, can you get me your exact model number on the furnace? Is there a flat fuse on the circuit board inside the furnace? Thanks.
