HVAC Leaking Water? Condensate Pump Troubleshooting

The condensate pump protects your HVAC system by pumping out the water it produces while it's operating. A pump gone awry can cause all sorts of issues we don’t want, so let’s get to the bottom of it!

Why Is My Condensate Pump Not Working?

When your condensate pump is not working properly, you may notice your HVAC system not working either. Perhaps your HVAC won’t turn on or your HVAC’s leaking water—these are signs of your condensate pump not working. The reason for this may be as simple as that it’s not plugged in!

Condensate pump troubleshooting

  • Search for the condensate pump. It's often located on the side of the furnace or air handler. It’s a small box with a slotted grate built into its case. It should have a power cord and a clear vinyl tube coming from the pump.

  • Follow the power cord from the condensate pump to its outlet. If the power cord isn't plugged in, the pump won't be able to run.

  • Look at the outlet to see if it's a GFCI outlet (a GFCI outlet has test and reset buttons). The GFCI may need to be reset. Try pushing the reset button. You can also check the power to the outlet by plugging something else into the outlet to see if it works.

    CAUTION: Do not reset a GFCI outlet more than once. If it trips multiple times in a row, it's time to call a technician.

If your condensate pump is working properly, consider other reasons to determine why your HVAC system is struggling.

What To Do If Your Condensate Pump’s Not Working

By simply plugging in the power cord on your HVAC unit’s condensate pump, your system should be good to go.

If plugging the pump back in doesn’t seem to pummel the problem, you may be dealing with a more complicated issue in need of an expert’s eye. You can reach out to one of our Remote Assist technicians for a free virtual diagnosis!
