You rely on your Carrier furnace to keep your home warm when temperatures drop. But your furnace isn’t doing its job when you’re met with an LED code you can’t decipher. One of the most common LED codes is the 1 Long 3 Short code, but what does it mean? In this blog, we’ll discuss Carrier furnace LED codes 1 Long 3 Short and how you can troubleshoot and fix the issue.

What are Carrier furnace LED codes?

The Carrier furnace is equipped with an LED light that helps diagnose furnace problems. The LED light flashes codes in a series of long and short flashes to indicate what the problem is. It’s important to understand the code your furnace is displaying in order to diagnose and fix the problem.

The Carrier furnace LED codes are divided into two categories: diagnostic codes and fault codes. The diagnostic codes are used to show the condition of the furnace’s operation. The fault codes indicate a problem with the furnace that needs to be addressed.

How to interpret Carrier furnace LED codes

Interpreting Carrier furnace LED codes is not difficult. All you need to do is count the number of flashes and compare it to the list of codes provided in the owner’s manual. Generally, the codes are grouped into long flashes (1 second) and short flashes (half a second).

For example, if you see two long and four short flashes, the code is 2 Long 4 Short. This code indicates that the furnace is running in low-heat mode. The codes can identify issues with the furnace, such as a blocked or dirty filter or incorrect thermostat settings.

Understanding the 1 long 3 short LED code

The 1 Long 3 Short LED code is one of the most common. This code indicates that the furnace is in lockout mode. This means that the furnace has detected a problem and has shut down its operation to prevent further damage.

Troubleshooting the 1 long 3 short LED code

The first step in troubleshooting the 1 Long 3 Short LED code is to check the filter. The filter should be clean and free of obstructions. If the filter is clogged, replace it with a new one. You should also check the pressure switch to make sure it is working properly.
