I did bring the relay with me but most of the electrical shops in my area didn't even cary relays to begin with. The ones that did didn't know anything about them. I tried a heating/cooling shop but they won't sell to individuals. I finally found what I needed at Grainger. The rep at the front desk was nice enough but still didn't seem to know how to match up what I needed. He gave what he thought was the best match but I'm not so sure. I had a 3/4 H.P. relay before but the one he gave me is a 1/2 H.P. Is that going to make a big difference? Should it work at all? What does the H.P. affect?
I got it home and hooked it up (it was very straightforward) but again all it did was hum. I do know the old relay was bad because when I took it apart some plastic pieces fell out so I'm still hoping there isn't any trouble anywhere else. I tested the low voltage leads that power the relay and they supply 25.6 volts as they should.
While sitting here I just notice that the box the new relay came in says
12A CONT.@ 125VAC
I don't see anything that has anything to do with low voltage although the two relays looked identical. Is the box stating the coil sould be powered with 120 volts...?
Also, guyod, thanks for giving me the heads up on how your pump worked out.
