The planner motor in my Minimax cu300 was working fine but when I attempted to restart after using it for a while it ?just hummed. The capacitor had a huge hole burnt through it. After replacing the capacitor it now starts right up. Are both capacitors running capacitors or is one a starting capacitor? Is there a centrifugal switch in the motor that could have caused it? Not sure what caused the burnout. Any suggestions would be much appreciated
