The blinking red light on your furnace typically indicates an error code or system fault that needs to be resolved. It is usually accompanied by a digital code that can be used to help diagnose the problem.
In your case, a blinking red light four times usually indicates a problem with the limit switch. When the limit switch is tripped, it prevents the burners from producing heat; the red light error code warns the user that this component needs to be replaced in order to continue receiving heat from the furnace.
It is a common problem on many furnace models, but fortunately it can usually be resolved easily by replacing the component. As always, if you are not comfortable making this repair yourself, it is best to contact a qualified heating technician to have them take a look at it.
What does 4 blinks on a furnace mean?
That typically means that the pressure switch is stuck open, preventing your furnace from running. A pressure switch is a safety device that ensures that the furnace vent is working properly. When it’s open (not activated), it will cause the furnace to blink four times when powered on, alerting you that there’s an issue with the pressure switch.
To fix the issue, you should turn off the circuit breaker and locate the pressure switch—it’s a small box or cylinder made of metal with a flapper inside and two or three tubes attached. Disconnect the tubes to see if any dirt or particles are blocking the flapper from closing.
If not, you should also make sure that the tubes are firmly connected to the blower/fan and heat exchanger. If the tubes are okay, the switch itself might be bad and should be replaced.
How do you fix a blinking red light on a furnace?
The most likely cause of a blinking red light on a furnace is a problem with the furnace igniter. If the furnace won’t turn on or stay on, you should start by checking the igniter. There are a few steps you can take to fix the blinking red light:
1. Check the furnace filter. A blocked filter can cause both the furnace turn off and the red light to blink. Replace the filter if needed and see if this resolves the issue.
2. Look for any indication of a gas smell. If there is any indication of a gas, turn off the furnace and contact a professional for help.
3. Check the circuit breaker. If the breaker is tripped, reset it and see if the red light stops blinking.
4. Check the furnace igniter. The furnace igniter can be accessed from the front panel of the furnace. Inspect it to see if it is broken or corroded and replace if necessary.
5. If all else fails, contact a professional to have the furnace inspected and serviced. A professional will be able to identify and fix the exact cause of the problem and get your furnace up and running again.
Should the red light from my furnace be blinking?
No, if you are noticing a red light blinking from your furnace, it could indicate a problem. Many furnaces have an indicator light that is either green or red. If the light is red, it often indicates an issue with the unit.
Common causes of a red blinking light include a malfunctioning thermostat, inadequate power to the unit, or a problem with the wiring. Before attempting to troubleshoot the issue yourself, it is best to contact a professional technician to diagnose the exact cause and to make any necessary repairs.
What does it mean when a red light comes on on a furnace?
When a red light comes on on a furnace, it typically indicates that there is an issue or malfunction within the system. The red light can appear as a steady light or a flashing light, which can indicate different types of problems and require different actions to be taken to resolve the issue.
Depending on the type of furnace you have, the red light may be an indicator of a system shutdown due to a limit switch tripping, or it may indicate an issue with the pilot light, flame sensor, pressure switch, or heat exchanger.
Depending on the heat source of the furnace, such as an oil furnace or electric furnace, other components may also be related to a red light issue. It’s important to note that if a red light is seen on the furnace, the system should NOT be used until the issue is resolved and the red light is no longer present.
Contacting a professional HVAC technician to diagnose and repair the furnace should be the first step to take when a red light appears on it.
What does a flashing red light mean?
A flashing red light typically indicates an emergency or potentially hazardous situation. Depending on the context, a flashing red light could mean a number of different things. In buildings, flashing red lights generally indicate the presence of an alarm system, like a fire alarm, that is signaling an emergency.
If the alarm system is linked up to emergency services, then it’s important to get to safety when seeing a flashing red light.
In some cities, a flashing red light indicates that a nearby emergency vehicle, such as an ambulance, fire truck or police car is approaching and for everyone to move out of the way. The flashing red light warns those in the vicinity of the emergency vehicles.
In the event of a power outage, the flashing red light surrounding an appliance could mean that it is not receiving power and needs to be restarted or reset.
A driver needs to be aware of their surrounding traffic when they see a flashing red light, as this could mean they need to stop or come to a complete standstill.
It’s important to be aware of the context in which a flashing red light has been seen, as this will usually give an indication of what it is warning of or indicating.
How do I reset my furnace sensor?
In order to reset your furnace sensor, you will need to identify where the sensor is located. The location of the sensor will depend on the model and make of your furnace. Generally, the sensor is typically located near the burners.
Once you have identified the location, you will need to turn off the power to your furnace. Once the power is off, you can go ahead and inspect the sensor. The sensor may have a reset button or a reset switch that needs to be pressed.
If there is no visible reset button, you will need to remove and reinstall the sensor. This will need to be done carefully as you do not want to damage the sensor. Once the sensor has been reinstalled, you can turn the power back on and test the system to see if the reset was successful.
How do you read a furnace error code?
Reading a furnace error code can be a tricky process, so it’s important to understand what each code means before trying to decipher it. Generally speaking, the first step is to locate the diagnostic light or LED display on the furnace.
This should be labeled with the type of fault code you are looking for, such as ‘Ignition fail’ or something similar. Once you find this, look at the code on the display to find the specific code number.
Different codes typically refer to different types of furnace problems. For example, an E1 error code may indicate an issue with the ignition system, while an E2 code could indicate a fault with the internal fan motor.
Other codes may refer to different components, such as the limit control, pressure switch, or the circuit board.
Once you know the code number, it’s important to make a note of what it means and the best way to address it. While some codes are pretty common and easy to fix, others may require the help of a professional.
It’s always best to contact a certified technician if you’re having trouble with your furnace, as they will have the experience and knowledge to diagnose and repair your furnace as quickly and safely as possible.

It may be required to be pressed once or twice in order to reset the furnace. Furnace reset buttons are different based on the model of each furnace, so it is important to check the user manual to identify the appropriate button.
What should you do if red light starts flashing?
If a red light starts flashing, the first thing to do is to determine the source of the red light. If the red light is coming from a smoke detector, then it could indicate that there is a fire or a buildup of smoke in the area.
In this case, you should immediately evacuate the area and follow your fire safety protocol. If the red light isn’t coming from a smoke detector and instead is coming from a security alarm, it could mean that there is an intruder present.
In this case, it is best to refrain from investigating on your own and to call the proper authorities, such as the police, first. If the source of the red light is something else, such as an appliance, then it could be a warning sign of a malfunction or a power overload, in which case you should shut down the appliance immediately and then have it serviced.
Where would you find these flashing red light signals?
Flashing red light signals can be found in various locations, depending on their purpose. On highways and other large roads, flashing red lights are often used as traffic signals. They are also used as railway signals, and are found at the side of railway tracks, usually mounted on tall poles.
Flashing red light signals can also be found at the top of tall buildings and other structures, acting as aviation warning systems. They are also used as security lighting, found near the entrances of buildings, in parking lots, and other areas where a potential intruder might be.
In some places, flashing red lights are also featured in warning signs, such as when hazardous materials are present.
