I think the place to start is your t-stat. First thing to check is that it has 12VDC power. If not then there's your problem. If 12VDC is present then jumper out the furnace and see if it comes on. Either that or if plugged into shore power you can jumper out the AC fan. If either works with jumpers then t-stat is cooked.
The furnace reset will only help if it is just the furnace not working.
