What does a furnace condensate pump do?

Condensate pumps are a type of centrifugal pump that is used to collect and disperse the hot water and liquid produced by condensation from heating systems, such as gas and oil condensing boilers, from the production of refrigerated air, such as air conditioning and refrigeration systems, air dehumidifiers and …

What happens if AC drain is clogged?

A Clogged Line Will Freeze Your AC System

A clogged condensate drain line will trap water in your air conditioner. As a result, the evaporator coil will eventually turn to ice. The moisture in the drain line can also freeze, which will cause your air conditioner to turn off.

How do I know if my condensate pump is working?

The best way to tell if a condensate pump is working is to simply pour water into the pump reservoir. If the condensate pump is working, the float will rise up as you pour the water, which will activate the float switch, and the pump will audibly turn on.

What happens when condensate pump stops working?

If that condenser pump fails, the water overflows the pump and spills onto the floor. That doesn’t necessarily mean the pump is bad; the problem could be just algae buildup in the pump’s check valve. So start your diagnosis by unplugging the condenser pump. Disconnect the drain line and empty the water into a bucket.

What happens if condensate pump fails?

What Happens If a Condensate Pump Fails? The biggest indicator of an issue with your condensate pump is that your air conditioner won’t turn on. The AC shuts off to prevent the pump’s water reservoir from overflowing. If your condensate pump is malfunctioning, it may need to be repaired, cleaned or replaced.

Why would a condensate pump fail?

Over time, the float and float components can accumulate debris, which will gunk up the system and possibly prevent it from triggering the float switch and draining the water. The float and float components are also susceptible to wear and tear over the years, which can contribute to a condensate pump malfunction.

How often should condensate pump run?

It is essential that the condensate pump system is regularly checked for correct operation. The frequency will depend on the environment in which the unit is operating but should be a minimum of once every 3 months.

What causes AC drain to gurgle?

The condensate gathers around the base of your evaporator coil and is moved outside via the condensate drain line. Over time, dirt, debris, and mold clogs your drain line. The clog causes the condensate to back up the line and gurgling sounds are produced in the process.

Does a condensate pump have a check valve?

For use with Condensate Pumps

A check valve keeps water from draining back into the pump which can cause the pump to short cycle. This small accessory can extend the life of the motor.
