回答“What is the F26 code?”It is a door switch error code, either the connecting wires are loose or the switch is defective. The door switch error code will also be seen if the door is not closed completely. Look fro loose wires first.
回答“Craftsman Walk-behind Lawn Mower stops running after primed?”Remove the gas cap and see if it runs. I have had two small engines that had defective gas caps and I drilled little holes in them and the motors worked fine after that. First remove the gas cap before drilling holes.
