Bosch furnace error light blinking

The process of heating a building is called “heating.” It is an important part of modern life and can be done with many fuel types. Today, most homes in developed countries have furnaces to heat them. Engineers use different methods to see if a furnace is running properly. One way is by using sensors in the furnace to measure what it’s doing and how it’s doing it.

The purpose of this light on top of a furnace is to let you know if something is going wrong that needs your attention. When this light starts blinking, it usually means something isn’t right with the furnace because there’s an error code on the panel.

Bosch furnaces have a few different error codes that are common for blinking lights on the control panel:

There are a few reasons why the error light might be blinking. The first and foremost is that the gas or power to the unit may have been interrupted. This will cause a red blink, then white, then turn off. If this is the case, you must check that all power sources are plugged in, and all the breakers are on. It could be the thermocouple if everything checks out and it isn’t turning on.

Some other causes could be high voltage interference within your home’s electrical system. That is usually indicated by flickering rather than a steady red blink. And finally, if your furnace has been on for more than 30 minutes, it will automatically shut down to prevent overheating components like the motor or blower fan.

The blinking light is an error message. This can be a sign of a few different things, but the error code will help you identify the issue.

When the lights are not blinking, they should be on and solid. If they are flashing and multicoloured, there is an issue with the thermostat or wireless connectivity.

If the lights turn off after you have blown air through all vents for 10 minutes and your blower fan runs continuously, there is likely a flame sensor issue, or it may need to be cleaned.
