When I press the bottom pedal to start the compactor it will not continue to run unless I hold it with my foot and wait for it to run full cycle.
You will want to check the top limit switch for the contacts to be open and for the arm on the switch being broken. You will also want to check for open contacts on the centrifugal switch. To check the centrifugal switch you will check across the 2 wires that are next to the red wire. Terminals 3 and 4.
