When the furnace 3 blink error occurs, most of the time, it can be caused by either a faulty thermostat or low voltage.

Most of the time when this error is occurring, it’s not because your furnace has a short in it.

This is the common problem that many users experience when they try to load their furnace 3 with wood pellets.

Blink error is a software issue that occurs when a furnace overheats and shuts off while trying to load it with wood pellets. It’s caused by the burner tripping and shutting down, which causes the thermostat on the furnace to shut off as well. This will reset shortly after.

This error message tells you that your furnace is currently running too hot.

The average time it takes for the power to go out in a data center can range from 12 hours to as little as five minutes. However, most of the data center power failures will be in the 15-hour range. The heater is designed to maintain the correct temperature by shutting off and on automatically, but it sometimes has problems with controller board failure.

This error message is indicating that your furnace has just shut off (blinked) due to a malfunctioning controller board in your boiler. Before you call for an emergency service worker or pay a visit to your local heating professional, try resetting this error by holding down both buttons on your thermostat for about 10 seconds until you hear three short beeps.
