Introduction to Carrier Furnace Error Code 33

Carrier furnaces are one of the most reliable and efficient home heating systems on the market. They are used in both residential and commercial buildings and provide reliable climate control all year round. However, like any other system, Carrier furnaces can experience problems from time to time. One such problem is the dreaded Carrier furnace error code 33.

Error code 33 is a fault code that indicates an issue with the furnace’s pressure switch. The pressure switch is a safety device that is designed to detect a blockage or restriction in the furnace’s exhaust vent. When the pressure switch detects a blockage, it will trigger an error code 33 and shut down the furnace. Luckily, this error code can be reset relatively easily.

What Causes Carrier Furnace Error Code 33?

Error code 33 is triggered when the pressure switch detects a blockage or restriction in the furnace’s exhaust vent. Generally, this blockage is caused by a buildup of lint or dust in the vent. This can occur due to a lack of regular maintenance or an issue with the furnace’s filter. Other causes of error code 33 include a faulty or malfunctioning pressure switch, an obstructed vent pipe, or a faulty exhaust fan.

How to Reset Carrier Furnace Error Code 33?

Resetting Carrier furnace error code 33 is relatively straightforward and can generally be done in a few simple steps. Before attempting to reset the error code, however, it is important to identify and address the underlying issue that is causing the error.
