Condensate Pump Not Working? Time For A Fix

When your air conditioner runs, it may develop a layer of condensation. If there’s too much condensation, the condensate pump is there to collect any excess, keeping your AC in shape. However, like most HVAC parts, the condensate pump can stop working properly. When that’s the case, you’ll want to check what’s wrong.

Check Your Condensate Pump

Do you see water collecting on the floor around your AC’s blower unit? If so, that’s a sign your condensate pump is not working. And if the pump stops working properly, the secondary float switch in the pump will prevent your AC from turning on at all.

How to check a condensate pump that's not working

  • If your air conditioner is running, turn it off to prevent the problem from getting worse before it can be fixed.

  • Look for water pooling around the air handler.

    CAUTION: Clean up any water immediately so that you don’t slip (this also prevents water damage to the walls and floors).

  • Check the settings on your thermostat. If you want heat, make sure it's set to "Heat". If you need cool air, make sure it's set to "Cool". "Off" will shut down your HVAC system entirely, and should only be used when you're doing maintenance or if you suspect your system is failing.

    Some thermostats also have an "emergency heat" option that is specific to heat pump heating systems. Like the name implies, it should only be used when your heat pump is failing and you need to switch to another heating source.

  • See if the condensate pump is plugged in to a working outlet. The condensate pump is a small box next to the furance that has a power plug and a clear tube coming out of it. Follow the plug and make sure it's plugged in. Double check the outlet to make sure it's working as well. If the GFCI has tripped, reset it.

If the condensate pump doesn't seem to be the issue, consider why else your AC is leaking water or won't turn on at all.

What To Do If Your Condensate Pump Stops Working
