Keep your Coleman DGAT070BDF manufactured home furnace running efficiently with genuine OEM replacement parts from Repair Clinic. The DGAT070BDF is a 70,000 BTU downflow gas furnace for manufactured home installations in the Coleman DGAT series; DGAT identifies the Coleman downflow gas furnace series for manufactured homes, 070 identifies 70,000 BTU input capacity, and BDF identifies the specific cabinet and fuel configuration. Coleman is a Nordyne brand channel product; the DGAT070BDF shares its platform with Nordyne’s downflow manufactured home furnace line with fully interchangeable service parts between both brand designations. Parts most frequently replaced include the igniter, flame sensor, draft inducer motor, control board, and blower motor. Browse the full Nordyne furnace parts catalog filtered by DGAT070BDF.
DGAT070BDF: Coleman 70,000 BTU Downflow Manufactured Home Platform and Nordyne Equivalence
The DGAT070BDF is part of Nordyne’s manufactured home downflow furnace platform, sold under the Coleman brand channel designation with fully interchangeable service parts. In the downflow orientation the burner box is at the top of the cabinet and the inducer draws combustion gases upward, causing moisture to accumulate near the inducer housing and accelerate bearing wear faster than in upflow furnaces. The DGAT070BDF control board is programmed for the downflow orientation and must not be substituted with a board from an upflow Nordyne or Coleman model; read and document the LED blink code before ordering any replacement component. The DGAT070BDF is an 80% AFUE non-condensing downflow furnace using standard metal B-vent and produces no condensate. For diagnostic guidance, visit the Coleman furnace troubleshooting section.
Most Replaced Parts on the Coleman DGAT070BDF
Igniter for the Coleman DGAT070BDF
Testing igniter resistance at room temperature with power off confirms failure in under two minutes; an infinite ohm reading means the element is open-circuit and must be replaced before any heating cycle can complete. The igniter is positioned in the burner box at the top of the downflow cabinet, accessed via the upper access panel after disconnecting power and gas. Browse Nordyne furnace igniter parts.
Coleman DGAT070BDF Flame Sensor
The flame sensor passes a micro-amp signal through the burner flame to confirm sustained combustion after ignition. Annual cleaning with fine steel wool extends sensor service life and prevents most early-season nuisance lockouts. Replace when the sensor recurs within the same heating season after cleaning. Browse Nordyne furnace flame sensor parts.
Draft Inducer Motor for the DGAT070BDF
Moisture condensation near the inducer housing in the downflow orientation accelerates bearing wear; grinding at inducer startup warrants replacement before complete bearing seizure creates a heating emergency. The correct inducer must be sized for the 70,000 BTU DGAT output class. Browse Nordyne furnace inducer motor parts.
DGAT070BDF Control Board
The control board is programmed for the downflow orientation and must not be substituted with a board from any upflow Nordyne or Coleman model. Read and document the LED blink code before ordering any replacement component; the blink pattern on the LED identifies the failed component or safety circuit. Browse Nordyne furnace control board parts.
Blower Motor for the DGAT070BDF
Test the run capacitor before ordering a replacement blower motor; a failing capacitor produces the same slow-start symptom as a failed motor winding at a fraction of the motor replacement cost. A capacitor outside its rated microfarad range causes limit switch trips from insufficient airflow across the heat exchanger. Browse Nordyne furnace blower motor parts.

Coleman DGAT070BDF Furnace Parts FAQ
What BTU output does the Coleman DGAT070BDF produce?
The Coleman DGAT070BDF delivers 70,000 BTU input capacity in the downflow configuration for manufactured home installations. The DGAT designation identifies the Coleman downflow gas furnace series for manufactured homes, 070 identifies 70,000 BTU capacity, and BDF identifies the specific cabinet and fuel configuration.
Is the Coleman DGAT070BDF the same as a Nordyne downflow furnace?
Yes. The Coleman brand is a product channel designation used by Nordyne for the same manufactured home furnace platform. The Coleman DGAT070BDF and its Nordyne-designated equivalent share the same cabinet design, platform engineering, and service components; parts are interchangeable between both brand designations.
My Coleman DGAT070BDF furnace keeps locking out. Where do I start?
Read the control board LED fault code first. On the DGAT downflow platform, the blink pattern on the LED identifies the failed component or safety circuit before any physical diagnosis begins. An ignition failure code points to the igniter or flame sensor in the vast majority of DGAT070BDF lockout calls; a pressure switch code should prompt hose and inducer inspection before switch replacement.
What type of venting does the Coleman DGAT070BDF require?
The DGAT070BDF is an 80% AFUE non-condensing downflow furnace for manufactured home installations. It uses standard metal B-vent in the downflow orientation, produces no condensate, and does not require PVC venting.
