Just did a furnace repair in Toronto to the same type of furnace, it was the pressure switch
. Make sure the drain is clear and the tubing isnt cracked from the pressure switch.

I think if it sits for a long time when it doesn't want to work and you bump up the heat .. it will kick on.. anyhow, he recommended that I switch out the thermostat.. although he thinks it may be the circuit board being bad.. for the life of me, I kind find where to look to find the flashes on the unit.. can anyone explain to me where it I should look in the unit? also, do you think I'm wasting my time on replacing the thermostat? thanks.......
below is what my furnace looks like on the inside.. cant find where its supposed to flash
