Dewalt 55155
Hums and starts sometimes but mostly not. Acts like capacitor but new one does not resolve. Motor and pump are now completely isolated from tank and still has problem. When it starts it runs fine. When it doesn’t it acts like it is trying and fan spins a touch. Helping it spin while it hums does not help it get going.
60uf is recommended and that is what I replaced it with. I accidentally ordered a 200uf so I have that one as well. Would that do harm? I am out of ideas. Fan turns easily and pump sounds like it is working smoothly.
