I figured I would piggyback on a previous topic, as I am at wits end, having looked for advice on PoolForum as well. My Hayward SuperPump has been working fine, although the motor has had problems 'kicking over' since installing a new dual speed new motor last year. I put the pump on a timer last summer with alternating off-on cycles of about 4 hours, but there were times I noticed that the pump was not running when it should've. I put it down to wet weather possibly affecting some connections, as the pump would always eventually come on.
Upon opening the pool this summer, I had to resort to using the 2x4 method, as well as cleaning the contacts occasionally. Then there was a lightning storm this week that knocked out power for a bit while the motor was running. Now the pump hums, but won't start for the last 2 days. I replaced the capacitor, just in case, but the electric supply guy thought the current capacitor looked ok. I've also looked at the connections and haven't noticed any burnt or obvious issues.
Before unhooking the motor and bringing to the shop, is there anything else I could check? Replace the Hi-Lo switch? A safe way to test the voltage?
