I was routing a practice board made of pine. I hit a knot and the router quit. checked circuit breakers and outlet. All fine. Is there a reset button? Craftsman router mounted on a table

On a table with a switch, the router needs the trigger locked on. I wonder if it could've turned off. Some routers don't have a trigger lock and the switch needs to be 'tied' in the on position. Either way manually pull the trigger to test.
Also you could try plugging the router in directly rather than through the table's switch.
Keep your fingers away from the bit.

If this is a variable speed router you may have burned out the electronics. If after plugging it into another outlet it still doesn't work, then you can try bypassing the switch. If it then works you will have to replace the part or use an aftermarket speed control
