Coleman’s diagnostic codes

Coleman’s diagnostic codes are the most common type used in the world. They are simple and easy to use, especially since they have been made digitally. The codes take the guesswork out of determining what’s wrong with your furnace.

The diagnostic codes provide a way to determine what type of problem your furnace is experiencing and the parts that need to be replaced.

Coal and gas furnaces require a special code for diagnosing or servicing them. But these codes can be found using the instructions below.

Coleman Mobile Home Furnace Diagnostic Codes help find the problem with a mobile home heater. The codes that it uses are different from the codes that other manufacturers use.

Coleman Mobile Home Furnace Diagnostic Codes:

-A: Normal operation

-A1: Temperature not reaching the setpoint value

-A2: Ambient temperature is too low and does not allow for combustion to occur

-L1, L2, L3, L4 or L5: Cycling thermostat or control valve is malfunctioning

Coleman furnaces are very popular in the market. With a wide range of styles, they are also quite affordable. Coleman furnaces also have diagnostic codes that help you troubleshoot problems and keep your furnace up and running.

One previous owner of an older Coleman furnace told us about her experiences with her old Coleman Furnace. She had a problem with the thermostat setting not working properly because something was wrong with the furnace motor’s thermistor circuit board. She could not figure out what was going on, so she bought another Coleman model that didn’t have this issue, so she went back to the first one thinking it might be defective, but there were no Coleman diagnostic codes for this situation.
