We have been having problems with the electrical part of our pump equipment and I'm trying to figure out if it's the time clock on the main pump or if it could be a problem with the pump itself or ???
We have 2 mechanical timers - one for the sweep and one for the main pump. The main pump was running fine for the last year since the time clock was replaced by a pool repairman. But about 3 weeks ago we discovered that the pump was shutting down even when the switch was on and the time clock was on.
The switch was very old so first I replaced the switch and repaired one of the wires which had been spliced. That seemed to fix the problem but then the next week the pump quit working again. At that point the pump would run if we jiggled the time clock so I pulled the time clock and checked all the wires and reattached it to make sure all the connections were good and clean.
Sometimes the pump would run when turned on and sometimes it wouldn't. If it didn't run it would start if we jiggled the time clock. We also noticed (for the first time) what seemed to be green sparking behind the time clock would occassionally happen.
So I have pulled the time clock and taken a close look at it. There is no sign of arcing anywhere on the clock. However the copper connections that close when the mechanical switch is moved to the on position appear to have some corrosion where the leads contact.
So I'm planning to try to clean off the corrosion and re-install the time clock to see if it will run.
I have never done this stuff before so I'm not sure if this is the best way to handle things. Is it possible that there could be a problem with the pump itself or with the electrical line/breaker?
Should I go ahead and re-install the time clock? Would it be better for me to go buy a new one? Or should I be calling an electrician or pool repair person at this point?
Thanks for any advice.
