The following issues may cause a red light to flash on your Dyna-Glo heater:
- Power fluctuation
- Faulty or dirty air filter
- Bad pressure gauge
- Ignition and combustion failure
- Malfunctioning pressure switch
- Bad heat sensors and switches
If you notice that your Dyna-Glo heater has a flashing red light, make sure to deal with the problem as soon as possible. Keep reading to get detailed information on how to tackle a Dyna-Glo heater with a flashing red light.
Why Is A Red Light Flashing On My Dyna-Glo Heater?
Dyna-Glo makes a number of different heaters, including gas and kerosene models. An active red light on a Dyna-Glo gas heater could be the result of different problems. The following are common reasons why your heater has a flashing red light:
Faulty Or Dirty Air Filter
If the air filter on your Dyna-Glo heater is faulty or dirty, the red light may start flashing. A dirty filter can affect the flow of air through your home. This may cause the heater to become inactive. When this happens, the heater may not be able to function properly.
Bad Pressure gauge
This is an important part of the heater. Its work is to check the pressure of the device, monitoring when it is too low, too high, or normal. If the pressure gauge is faulty, chances are the red light on your heater will start flashing.
Ignition And Combustion Failure
A blinking red light can be due to a fuel error or an ignition problem around the combustion assembly. When this happens, it is possible that your flame sensor just needs to be cleaned.
If the flame sensor isn't clean, it might not detect the flame even if it is present, resulting in a blinking light. Sandpaper with a very fine grit can be used to gently clean your sensor.
Even though cleaning the flame sensor is a relatively straightforward remedy, it might not be effective. A problem with the gas valve or the ignitors is another possibility. However, fixing either of these issues is something that is best left to the expertise of trained technicians.
Malfunctioning Pressure Switch
The heat exchanger and the pressure switch are two components of a heater that work together to ensure that the system is expelling harmful gases out of the system. Problems with pressure switches may also indicate a clogged condensate drain or blocked vent.
Bad Heat Sensor And Switches
A number of roll-out switches that are located on the interior of most Dyna-Glo heaters. These switches monitor heat.
These switches act as switches that can tell whether the heat exchanger has reached an unsafe temperature. They keep an eye on the temperature within the heat exchanger to ensure that it doesn't get too hot inside the heat exchanger.

What To Do If A Red Light Flashes On Your Heater
If your heater has a flashing red light, here are things you can do:
Use Multimeter To Check For Issues
Conduct some tests on your heater to identify any potential issues. You can't tell that there is a problem with the heater simply by looking at it unless you have received specialized training.
If you do not have this level of training, you can try testing the heater in order to determine whether or not it has thermocouple or other problems. To conduct the test, you will need a multimeter, which is a tool that combines the functions of an ammeter, voltmeter, and ohmmeter into a single device.
Before you test your heater, you need to be sure that it is not plugged into an outlet and that it is turned off.

Reset Your Heater
Most electrical devices require a reset to keep functioning. Your heater's ability to perform properly may be negatively impacted by minor internal faults within the device, which a factory reset will solve.
Heaters come in different types and models. The procedure for resetting a heater differs depending on the model. Certain models feature reset buttons specifically designed for that purpose, while others don't.
Examine the device itself or consult the user manual to look for hints about the possible locations of the buttons. If you are able to locate the button on your device, press and hold it for the duration necessary for the heater to be reset.
But if there isn't a visible button or one that's specifically designated for resetting the device, you may need to unplug the heater from the socket and leave it unplugged for a few minutes.
After that, plug the heater back in and ensure that the power is restored to the device. Next, check the indicator light. If the problem is minor, the blinking light should stop immediately.
Contact An HVAC Specialist
If you have determined the reason why the red light on your heater is blinking but can't deal with it on your own, you can contact a qualified HVAC technician to have it fixed as soon as possible.
Can A Bad Flame Sensor Cause A Flashing Red Light On Heater?
Yes, a faulty flame sensor can pose a significant safety risk and cause the red warning light on your heater to flash.
Every heater has a flame sensor, and its job is to determine whether or not the heater fires up properly. It makes communication between the gas valve and the furnace firing easier to accomplish.
However, if the flame sensor is not operating properly, natural gas or propane could leak into your home. A faulty flame sensor may fail to detect the heat that is produced when a furnace is turned on. This can cause the gas valve to be closed while it shouldn't, which in turn causes the red light to flash.
Consequently, a bad flame sensor can cause the gas valve to remain open even though the heater is not actually burning the gas. This could result in a gas leak, which can be dangerous.
How Long Will A Dyna-Glo Heater Last?
The lifespan of a Dyna-Glo heater can be affected by a number of variables, such as the frequency with which it is utilized and how it is maintained.
In most cases, users expect their heaters to last between 15 and 20 years. The heater has the potential to last even longer if it is well maintained on a routine basis. In a similar way, a heater that has been neglected and used frequently may not outlive its guarantee.
To Wrap Up
If a red light flashes on your Dyna-Glo heater, this could be the result of a power fluctuation, dirty filter, or ignition and combustion failure, among other issues.
To fix the problem, all you need to do is check for wiring issues or try resetting your heater. Don't hesitate to call a professional if you cannot deal with the problem alone.
