Introduction to Carrier Furnace LED Codes

Carrier furnaces are equipped with LED lights that help display the status of the system. These lights can blink in a variety of patterns, each of which indicates a different issue or status. One of the most common is the 2 short 4 long LED code. This code is usually seen when there is a problem with the system.

The Carrier furnace LED codes can vary slightly depending on the model, age, and type of furnace, but the 2 short 4 long code is typically the same across all models. This code indicates that the system has detected a problem that needs to be addressed.

What Do 2 Short 4 Long LED Codes Mean?

The 2 short 4 long LED code typically indicates that the system has detected a problem with the pressure switch. The pressure switch is an important part of the furnace that helps ensure that the system is working properly and safely. It senses the pressure in the furnace’s combustion chamber and signals the system to shut off if it gets too high. When this code is displayed, it means that the pressure switch is stuck in the open or closed position and needs to be reset.

Common Causes of 2 Short 4 Long LED Codes

There are a few common causes of the 2 short 4 long LED code. One of the most common is a faulty pressure switch. This can occur when the pressure switch gets stuck in the open or closed position, preventing the system from functioning properly.

Other common causes of this code include a clogged filter, a faulty inducer motor, a faulty blower motor, or a blockage in the system. These are all relatively easy issues to diagnose and repair.

How to Troubleshoot 2 Short 4 Long LED Codes

If the 2 short 4 long code is displayed on your Carrier furnace, the first step is to check the pressure switch. This can be done by removing the cover of the furnace and inspecting the pressure switch. If the pressure switch is stuck in the open or closed position, it needs to be reset.

Next, you should check the filter. If the filter is clogged, it will need to be replaced. If the filter looks clean, you should check the blower and inducer motor for any signs of damage or wear. If the motors are damaged, they will need to be replaced.

Finally, you should check for any blockages in the system. If there are any blockages, they will need to be removed.

How to Reset the Carrier Furnace After Fixing a 2 Short 4 Long LED Code

Once you’ve identified and fixed the issue causing the 2 short 4 long LED code, it’s time to reset the system. To do this, turn off the power to the furnace and wait a few minutes. Then, turn the power back on and the system should reset itself.
