Coleman Furnace will not turn on

My Coleman furnace - Model #G8T will not fire up. I checked the following:

1. Circuit breaker not tripped
2. Power to the outlet that unit is plugged into is ok.
3. Unit was working fine until I turned it off from thermostat overnight
4. Unit would not turn on when I turned thermostat back on for heat.
5. Troubleshoot manual said to check fuse.
I cannot locate fuse to check if blown
6. Can anyone tell me where the fuse is??
7. Could it be something else that I can check before I call the Service Repair??

Thanks for any help.
