Keep your Coleman DGAT070BDD heating through the season with genuine OEM replacement parts from Repair Clinic. The 070 code identifies a 70,000 BTU input in Coleman’s DGAT series, a Coleman Evcon downflow furnace line built for manufactured homes and now supported by Johnson Controls alongside York and Luxaire. Parts replaced most often include the DGAT070BDD igniter, the flame sensor, the draft inducer motor, and the control board. Check your build on the DGAT070BDD parts list, then browse all Coleman furnace parts.
DGAT070BDD Revisions and Downflow Layout
Later suffixes of this 70,000 BTU DGAT, such as BDE and BDF, follow the BDD; ignition parts are typically shared across them, while control boards should be matched to the suffix on your data plate. The DGAT is a separate series from the Coleman DGAA070BDTA, so do not assume parts cross between them. In the downflow layout, heated air leaves the bottom of the cabinet into the floor ducts and the burner section sits above. The DGAT070BDD heat exchanger depends on full blower airflow to stay below its limit. The DGAT070BDD manual and DGAT070BDD diagram show codes and wiring.

Most Replaced Parts on This Coleman Furnace
Igniter
Test the hot surface element for continuity with power off; an open reading confirms failure. Replace the igniter before suspecting the gas valve or board.
Flame Sensor
A burner that lights and shuts off within seconds has a fouled DGAT070BDD flame sensor. Clean it yearly with fine steel wool and replace the sensor if lockouts continue.
Draft Inducer Motor
The DGAT070BDD draft inducer motor clears combustion gases before ignition. Grinding at startup means worn bearings; replace the inducer motor before it seizes and leaves the home without heat.
Blower Motor and Capacitor
Slow starts or weak airflow usually begin with a weak run capacitor. Test it against its rated value before replacing the PSC blower motor.

DGAT070BDD Furnace FAQ
What BTU input does this furnace have?
The 070 code identifies a 70,000 BTU input. Confirm the exact rating on the data plate inside the cabinet.
Is the DGAT070BDD the same as the BDE or BDF?
They are successive revisions of the same size. Ignition parts are typically shared, but match the control board to your exact suffix.
Why does my furnace ignite and then shut off within seconds?
A fouled flame sensor is the usual cause. Clean the rod and replace it if the pattern continues.
How do I read the DGAT LED fault code?
Count the LED flashes and match the pattern to the chart inside the blower compartment door.
