What Does Four Flashing Lights on a Coleman Evcon Furnace Mean?

According to HVACpartstore.com, four flashing lights on a Coleman Evcon furnace means that "a primary or auxiliary limit switch has opened its normally closed contacts." This indicates that only the air blower for the furnace operates.

There are 12 different flash codes that may occur whenever the system inside of the furnace needs to be changed or fixed. These problems are attributed to the control circuit board kit. A customer is able to buy a separate circuit board if the one that came with their device is not functioning properly.
