Thanks Pool Clown for the reply. Turns out the one I bought in the link I posted is actually a 24 volt DC relay!!! So much for my detective work. My original relay is 120 volt AC. Looks closely at the picture in the link and you can just make out the 24VDC in the upper left hand corner, 3rd line down from the top. Point taken on potential amperage increase. We have the Aquapure (chlorine generator), but water is heated via a solar system, not electrically or with gas. LegsOnEarth provided part# R0658100, so I Googled it and when looking at the images and spot checking several, they are DC, not AC. Was there some recent change in the pool industry to go from AC to DC? I have a single speed motor. So many of the images show the relay tilted on it's back or side so you can see the connectors, but they don't say it is a DC relay anywhere in the specs. VERY frustrating! AND some of the prices for $1.75 worth of materials in the relay is just asinine. $95.00!!!! Really??? OK, done with the rant. I kept searching while typing this up and may have found one: http://www.superiorlighting.com/Double_Pole_Single_Throw_Relay_with_120V_Coil_p/143t136.htm?gclid=COj_mpCc68UCFUZffgodzFQAVg&utm_source=googleshopping&utm_medium=cse&kwid=kwid It is upside down in the picture and has "quick connect" type connectors instead of screw, but it might work. How I found this was by searching on "double pole single throw relay 120v". NOW I'm seeing some options! This is a link to a pdf data sheet from OMRON that helps decipher the part number: http://www.newark.com/pdfs/datasheets/Omron/G7L.pdf. So a GL7-2A-BUBJ will get me screw terminals instead of "quick connect" terminals. Still searching but now I think I can find what I need and won't have to give up my left arm either.

No offense, but that's not exactly the answer I was looking for. I know it's the relay and I don't need a pool retailer to tell me what I already know. My question is about the new relay and whether it is "bad" based upon the noise it is making. I could not find an exact match for a replacement relay, 25 amp (new) vs 30 amp (original). I have e-mailed the seller of the new relay describing the problem. Waiting to see what they say.

Hello. Here is my system installed in September, 2007: Jandy AquaPure 1400 with a Stealth 2 hp pool pump motor. I believe I have a failing relay, this is the original, info stamped on the plastic cover: _________________________________________________ HLR6100-2ABJCF2-AC100/120V 30A / 277VAC 3hp / 240/265/277VAC 1-1/2hp / 120VAC Coil: 100/120VAC Innovative Pool Prducts (yes, products is spelled like that) _________________________________________________ I can tap on it to get it to turn on and in some cases to turn it off. Based upon my detective work, I bought one of these: http://www.poolpartsonline.com/p-57361-3hp-relay-intellitouch-520106-opt-9237-135.aspx but did not use the wiring "harness". The one I bought is identical (Omron) but cost less than half the price of the one in the link. I turned off the breaker and moved one wire at a time from the old relay to the new relay so there would not be any "crossed" wires. Verified my connections were tight, flipped on the breaker and manually moved my timer to the "on" position. The new relay instantly started "high speed chattering". The pool pump did turn on and stay on, but clearly the relay should not be making all this noise. After no more than 10 seconds I turned it off. Double checked everything, turned it back on with the same results. Reversed the wiring until all wires were back on the original relay. Manually moved the timer to 'on', tapped the relay and it turned on (quietly, no noise other than the initial click). Did I get a bad relay? I've searched high and low using the information on the side of the original relay but I get virtually no 'hits'. What bothers me about the new relay is that it is rated at 25 amps and the original is 30 amps. Could this difference cause the high speed chattering? Thank you for any advice you can provide.
