Question about Little Giant Vcma-15uls 554405 Vcma Series Automatic Condensate
Pump installed in new furnace last fall worked fine til last month. Runs extended time but draining very slowly. Have been putting white vinegar in pump holding tank regularly. Does not seem to have any residue build - up. I'm pretty handy if I know where to start.

Thank you for posting your question here on Fixya.com.
What is the problem you are having that makes you think it is the pump? The pump has nothing to do with furnace operation; it is there to remove condensate and humidification water from the furnace to a drain or sink. If the furnace is tied to the pumps secondary float to allow the pump to shut off the furnace due to high water, disconnect the switch and wire nut the two wires from the furnace together.
If you want to fix the pump, a few common problems center on lint and dust buildup in the reservoir and/or tubing. You can use compressed air to blow out the discharge line. Be careful to keep the end in a safe direction...you would be surprised who much slimy crud builds up in the tubes. You can take the top off the reservoir and clean inside it. On the coldest days, check to be sure the water is not somehow freezing within the discharge, which would only seem possible if for some reason the tubing leads outdoors.

You might have 2 problems. The GFIC might be wired wrong or the pump wirng might be compromised with moisture. The noise issue? Are you running this unit without submersing it? They will burn out if you do. To get a more accurate running sound, submerse it with a flexible pipe so you can run it in a 5 gal bucket without losing the water.
It's possible a bearing is burned out.

There could be gunk in the bottom....then the float does not work right and the pump will not pump either...
remove the pipes and/or hoses and then the screws that hold down the top....clean the inside really well and reassemble... that may work,,,, but it may already be burnt up...
if cleaning does not work the replace the pump...you should be able to buy a new one at a HVAC supply house or some place like HD or Lowes...they will be in the 50.00 or less range...
