Circulating Pump Capacitor?

airliebeach · 2021-01-17 00:31:39

Hello All. Pump not operating on setting 2 or 1. Setting 3 operates ok. I suspect capacitor. How do I know if its a starting cap or running cap? How exactly are the different speed settings set? (electronically speaking) Can cap cause this problem?

If old type circ pump (as distinct from the A rated electronic ones) then only 1 capacitor AFAIK, speed control on these (old) was achieved by resistances for speed1 and 2.
