We don’t need to panic about this error code. There are many reasons for a furnace to display the four flashing error codes. The most common cause is a blown circuit or bad contacts on the furnace switchboard.

To fix this, we need to go through the following steps. First, we must unplug the power and wait for five minutes before plugging it back in. Next, we need to check if there is any dust accumulation around the switchboard, clean it up with a dust cloth if necessary, and then turn on the power again.
