Sounds like your furnace isn't responding to a call for heat. Could be a problem with the thermostat or thermostat wiring. First thing to try is to connect the leads on thermostat terminals R & W together. Does the furnace respond? If not then go to the thermostat terminal strip on the furnace and jump the R & W terminals. After making sure the blower compartment panel is securely in place does the furnace respond?
Could be a problem with the board. Since you should get a response with R & W jumped. If the inducer doesn't run either due to a bad motor or bad board then you should be seeing an error sequence on the LED. Sine you aren't it makes the board suspect.
Nothing in your last post changes my opinion that this is a board problem. If I was on your job and determined what you have told me then I'd replace the board. You have 24 volts to the board and no response to a call for heat and no error message. That make the board the prime suspect.
That's a circuit breaker not a reset switch. You can reset by powering the unit down waiting a couple minutes then power it back up. If the board was functioning normally you should get an error displayed if you get no response to a call for heat.
