Tommy, I can do all of those things, but at this moment in time my extended family is due here for a birthday party. I'll get the info, likely by Monday evening. Will that work? Photos and nameplate(s)?
Will do, and thanks.
Test; I've tried twice to upload photos and access is denied. Are you getting these?
I'll do that, Tommy, as soon as the battery in my 2004 digital camera recharges. In the meantime, let me tell you about the photos in advance. The wiring consists of 4 sets of wires (black, white, red and ground), all common to the blower motor and the power source. I've tried the wires from the pump to the black and white, switching around to double check. Nothing. I didn't use the red set because in 20 years the wire nut on that set has never been removed. I honestly suspect the wall switch, because when I first tried to turn on the (old) pump, there was a definite noise...not a good one, either. Then silence.
Anyway, photos on the way.
Ok, will await on the photos, not a problem.Does the entire cooler have a switch for power?The post sounds like they have 2 separate switches?Usually the pump is running when the blower is on as long as there is water.Is there a low water level switch or another failsafe to keep power from the pump?
Make and Model may help to find a manual?
Water level is high. The blower and switch are two-stage; low and high. I've tried pump only and low and high cool; nothing coming out of the pump.
Dang. I'll have to climb back up on the roof, and that won't happen until tomorrow (left knee is shot). It's an Emerson with 2 speed connection. Low speed to red, common to white, high speed to black.
Ok, well that gives the information, no need since you posted the information.. That is what I was trying to read, the speed connections.I would first do this:Get a drop cord and connect a couple wires to the low speed connections white and red.Stick the ends in the female end of the drop cord.Then plug it in and see if the motor runs.Do the same for the high speed.I do that when quick testing motors only, just to verify that they run ok.Unplug as soon as it runs for a couple seconds.You will need a voltage tester if it runs fine on the cord, to test the leads going to the motor in the cooler.Something would be interrupting the power at that point and the tester will help to isolate and find the issue.
Okay Tommy, I can do all that. But, as I said, the blower motor is running fine; high cool, low cool, high vent, low vent; all from the wall switch. Just no water from the pump. I'm not that great with electricity, but doesn't that verify the problem isn't in the blower connection?
Okay, I'll give it a shot. Couple days of cooler temps coming up, good time to check this stuff out. Thanks, Tommy.
Another day, another tripped breaker. Stand by, checking it again tomorrow (turns out some of my outside plugs in my 35-year old house are not as reliable as others). I want to give it one more shot, this time with the high-speed connection first. Should the little pump itself work using the drop cord trick? (p.s. I had to find out that a drop cord is what I call a heavy-duty extension cord; regional differences, right?)
Thanks again for your attention to detail on this.
Tommy, I hooked up the drop cord as described to each component; water pump, high speed blower, and low speed blower. All work fine. So I re-wired the pump:
Pump hot lead to high-blower hot lead (black), pump common to blower common (white). No response (except when I turned the pump on at the wall switch, I thought I detected a click). I didn't hook anything up to the low-blower hot wire (red).
Think the problem is at the switch? I have an 8-range multi tester for further exploration.
Thanks again. Hopefully our issue won't extend much longer.
Okay, good intel! The ONE switch has five settings: pump only (water pumps to the pads), low cool (pump and blower), high cool (pump and blower), and low and high vent (blower only). So I'll take the switch apart (it has blue electrical tape around the wiring) and see what's inside...after I turn off the juice.
