How to Troubleshoot a Broken Condensate Pump

Updated: Feb 10, 2023

Condensate pumps work to pump the water that is created in a heating or boiling system. But if your condensate pump isn’t functioning as it should, it might need to be cleaned, repaired, or potentially replaced.

If the condensate pump isn’t working correctly, it’s dangerous to run your air conditioning system because it can cause water damage and other costly repairs in the long run. Knowing how to troubleshoot a broken condensate pump is essential to ensure your system gets the repairs it needs before a bigger issue occurs. Here’s how you can troubleshoot your condensate pump in five simple steps.

Step 1. Turn the Power off to Your AC and Condensate Pump

If you suspect your condensate pump might be broken, turn the power off to your AC and the condensate pump. Make sure you turn off the power to the high voltage and low voltage wires from the pump.

Step 2. Check the Float

All condensate pumps have a float, which is located at the top of the pump. This small piece can sometimes become stuck and cause the pump to shut off. If the float is stuck, simply tap on it until it can move freely again. If you notice the float is cracked or damaged, you will need to replace it.

Step 3. Clean the Pump

After completing steps one and two, clean the pump thoroughly. Remove the outer housing of the pump and dump the water from both the pump and the tank. Use warm soapy water and a clean washcloth to clean the entire unit, including the float.

Step 4. If It’s Still Not Working, Remove the Pump

If the pump is still not working after cleaning, use a pair of wire cutters to cut the lines that are connected to the pump. Be sure to leave part of the wire so you will have some to work with when replacing the pump.

Step 5. Remove the Old Pump and Install the New One

Carefully remove the old pump from its position and replace it with a new pump. Reconnect the electrical wiring and insert the new plumbing lines. Once you have installed the new pump, turn it on and pour water into the pump to test. If the pump stops running once the water is poured, continue adding water until it works correctly.
