Determining Coleman Electric Furnace Parts
The best way to determine what part number you need it to look for the number printed on the part itself. If that’s not possible, then this cheat sheet may help you determine which parts you need for many common Coleman electric furnaces.
To use this cheat sheet, first locate the model number of your furnace by looking at the data plate on the front of your furnace. It may look something like this: EB15B or 3110B750. The first letters or numbers are considered the series. The ending letters or numbers are considered the model.
TIP: To search for your furnace on this page, place your cursor below the page header and type ‘Control F’ and enter the model number.
