So, this is one of the reasons behind the error code E12 issue.Ĭonnecting the heating coil again can solve this issue. When this coil doesn’t work, the combustion can’t take place.Īs a result, the combustion motor fails and error code E12 appears. Heating coils convert electricity into heat. If the heating coil is turned off or disconnected, this problem may occur.
There are some common reasons which lead to the E12 error code of Trane furnaces. The ignition circuit creates the spark for the combustion motor to work.Įrror code E12 can also occur due to pilot assembly errors. It helps to heat or cool and in air conditioning. And it’s related to the combustion motor which is an integral part of the furnace. Trane also does the same.Į12 error code is also one of the provided codes. This code helps to quickly identify the actual cause and fix it accordingly. Very often, these common problems are indicated by some equipment error codes.
That’s why manufacturers always include common problems and fixes in the user manual. What is the E12 Error Code?Įlectrical components are bound to malfunction after using for a certain amount of time. So, please keep reading along to know more.
