Maintain dependable heating from your Coleman DGAA056BDTA with genuine OEM replacement parts from Repair Clinic. The 056 code identifies a 56,000 BTU input, the smallest common size in Coleman’s DGAA gas furnace series, a Coleman Evcon line supported by Johnson Controls alongside York and Luxaire. The parts replaced most often include the DGAA056BDTA draft inducer motor, the igniter, the flame sensor, and the blower capacitor.

Coleman DGAA056BDTA Furnace Details
This DGAA056BDTA furnace shares the DGAA layout with the 070 and 077 sizes, but its burner, orifices, and blower are matched to the 56,000 BTU input. The BDTA suffix is a production revision, so confirm control boards and pressure switches against your exact suffix, while igniters and flame sensors are usually shared. The sequence runs inducer purge of the DGAA056BDTA heat exchanger, pressure switch proving, igniter warm-up, gas valve opening, and flame confirmation. The LED code identifies which stage failed. The DGAA056BDTA manual and DGAA056BDTA diagram document wiring and fault codes. For DGAA056BDTA repair steps, use the model troubleshooting guide.
Most Replaced Parts on the DGAA056BDTA
Draft Inducer Motor and Startup Noise
The inducer vents combustion gases and creates the draft the pressure switch must sense. Humming, grinding, or a slow spin-up means the bearings are wearing. Check the vent and pressure tubing, confirm the motor reaches full speed, and then replace the inducer motor if it does not.
Blower Motor and Run Capacitor
Weak or inconsistent airflow often begins with a failed capacitor. Test the run capacitor and replace it if it reads more than 5 to 10% below the rating printed on the installed part. Replace the blower motor only if a good capacitor does not restore speed.
Igniter and No-Heat Calls
Read the fault code first. If the inducer runs and the pressure switch closes but the burner never lights, inspect the DGAA056BDTA igniter for cracks and replace the igniter, handling it only by the base.
Flame Sensor and Short Cycling
When the burner lights and shuts off within seconds, the DGAA056BDTA flame sensor is usually coated with oxide. Clean the rod, and replace the flame sensor if the furnace still short cycles.

DGAA056BDTA Furnace FAQ
Why won’t my DGAA056BDTA turn on?
Read the LED code. The common causes are a cracked igniter, a pressure switch held open by a slow inducer or blocked vent, or a control board fault.
Which DGAA056BDTA parts are replaced most often?
The draft inducer motor, igniter, flame sensor, blower motor and capacitor, and control board. Each is shown by position on the diagrams tab.
Are BDTA and BDTB parts the same?
Most ignition and sensing parts are shared across revisions, but control boards and pressure switches can change. Match those to the exact suffix on your data plate.
Why is airflow weak from my furnace?
Check the filter, then test the blower run capacitor. A weak capacitor slows the motor and reduces airflow before the motor itself fails.
