You may have just noticed a small red light on your furnace that you hadn’t seen before. That’s normal! If the light glows solid amber or yellow, everything is functioning properly, indicating you have a happy furnace. However, if the light is blinking, your heating system is trying to communicate an important issue.
In this blog, we’ll explain what the blinking red light on your furnace means, how to interpret the error codes it displays, and the common problems they indicate. We’ll also cover how Doc Dancer Plumbing, Heating, AC & Generators can quickly and efficiently resolve these issues, keeping your home comfortable throughout the cold months.
When it comes to furnace repairs and tune-ups, you can trust the HVAC professionals at Doc Dancer for expert solutions that meet your needs.
What Does It Mean When My Furnace Light Is Blinking?
Your furnace can’t talk, but it has its own way of letting you know when something is wrong. In addition to strange noises, lack of heat, or unusual odors, a blinking red light is a key indicator that your furnace is experiencing an issue.
Most furnaces, whether gas or electric, are equipped with a blinking red light that serves as an important status indicator. When this light flashes, it’s sending you an error code. Think of these signals as Morse code for your HVAC system, each pattern pointing to specific problems.
To interpret the blinking light, pay attention to the pattern of the flashes. The light typically sends a series of short and long blinks that correspond to error codes specific to your furnace model. These codes are essential for diagnosing the issues your furnace is facing. Your furnace manual will usually include a section on troubleshooting that lists the error codes and their meanings. If you don’t have the manual, you can often find it online by searching for your furnace model.
If you don’t see a red light at all when you know it should be on, your furnace may not be receiving power. In this case, check your circuit breaker box to see if the breaker for the furnace has tripped.
Common Furnace Error Codes and Their Meanings
When your furnace’s red light begins to blink, it’s sending important signals about its performance. Here are some common error codes and their meanings:
Blower Running After Power-Up
When power is restored to your furnace, you might notice the blower running immediately. This can trigger an error code, but it often means the system is performing a self-check and should start soon. If the blower continues running without the furnace firing up, it may require attention from a furnace repair company.
Gas, Ignition Failure, or Proving Fault
Error codes related to gas issues, ignition failure, or flame proving failures usually indicate problems in the burner assembly with gas furnaces. A dirty flame sensor is often the cause and may just need cleaning. However, these codes can also signal issues with the gas valve or ignitors, which can be dangerous without the expertise of a skilled HVAC contractor.
Pressure Switch and Inducer Failures
Inducers and pressure switches are essential for proper venting of your furnace. If these components fail, serious safety concerns can arise. While you can check for blockages in the chimney or exhaust, these complex parts are best left to professionals. Reliable furnace repair services are crucial, as experienced technicians can diagnose and resolve these issues safely.
High Limit Switch & Roll-Out Switch
The high limit switch detects the heat inside the heat exchanger and tells the fan to shut off to prevent overheating. Roll-out switches detect excessive heat in unintended areas. If you receive a high limit switch error code, start by replacing your furnace filter, as a clogged filter can lead to poor air quality. If that doesn’t fix the issue, contact skilled technicians who regularly handle heating and air conditioning systems.
Furnace Lock-Out
A lock-out happens when your furnace has attempted to ignite multiple times without success. To reset it, cut the power at the breaker, leave it off for a few seconds, then turn it back on. Sometimes, like your computer, HVAC systems respond well to a reboot. However, if the problem persists, it’s critical to call a furnace repair service to diagnose the underlying cause and ensure your furnace can continue to provide heat.
