I am installing a replacement water collection pump to the humidifying system attached to the blower. The old pump has the brown and blue wires connected opposite of how the new pump came wired. What should I do? change the new one or go with it as it is The old pump was installed at the same time as the whole heater and a/c system was by a competent professional specializing in heating and cooling. I trust his work as it has held up to the test of time in addition to all the early indicators of professionalism like clean work, respect of my home, follow up availability, etc. The pump I am installing is a Little Giant VCMA-15ULS aka item number 554405. I am one who reads instructions 1st then again while installing. I have read these a dozen times and they are dreadful. The information about the safety switch is even worse and doesn't match the original either. The old unit seemed to be wire through the safty swich but used the NO post to bypass the functionality of it as I do not have an audio alarm. The new pump is not wired through the switch. Am correct in associating the term alarm with audio? Will the pump work without the switch in the circuit? And should I leave it wired as it came from the factory or change it to match the one I am replacing?
First do not change the factory wiring, what voltage is the pump wired for, what voltage is supplied to the pump.
then we figure out the rest
also what do the instructions say about the pump
NO stands for normally open contact-which means during operation is open which means off.
will be glad to help 865-888-1220

Hi,
Either the float is stuck or the pump is stuck...
To release the float a good shot to the side of the pump is all that it will take....
If that does not work then a few screws and the top will come off.. the pump is a very simple spinner.. make sure ther is nothing jammed in there...
if that all checks out replace the unit, the motor is shot....
you should be able to find a new one at a HVAC supply house for around fifty bucks...or check www,grainger.com for a replacement condensate pump.

I assume the unit is overflowing, because the pump is not running. Check th hose connection and be sure the line bringing the water into the pump is inserted in the opening. Can you hear the motor run? You can remove the top, and be sure the float switch is working and that the pump inlet is not clogged with debris. Sometimes you'll get mold and dirt mixed with water clogging the inlet. If the motor doesn't run, and the switch works, then it probably isn't worth fixing as you can buy these from 35.00--50.00
SOURCE: How do I wire the safety overflow switch to my
The overflow switch needs to be wired in a manner that interrupts the HOT (black?) side of the wires going to the water inlet valve or it's circuit.
