Get your Rheem RGDG-07EAUER back to full heat with genuine OEM replacement parts from Repair Clinic. The RGDG series is Rheem’s downflow gas furnace line, and the 07 code places this model in the 70,000 to 75,000 BTU input class (confirm on the data plate). Rheem and Ruud share one platform, so equivalent Ruud models use the same service components. Parts replaced most often include the control board, the RGDG-07EAUER flame sensor, the igniter, and the inducer and blower motors. Confirm your part on the RGDG-07EAUER parts list, then browse all Rheem furnace parts.
Downflow RGDG vs RGPH: What Changes for Parts
In this RGDG-07EAUER furnace, heated air leaves the bottom of the cabinet into a floor plenum, so the blower, limit placement, and board timing are set for downflow. Do not borrow boards or blower parts from the Rheem RGPH-07AUER or other models even at a similar input; order from this model’s own list. The RGDG-07EAUER heat exchanger depends on full airflow, so limit trips usually start with the filter or a weak capacitor. The RGDG-07EAUER manual and RGDG-07EAUER diagram show the sequence of operation and LED codes. For RGDG-07EAUER repair steps, open the model troubleshooting page.
Failure Modes on This Downflow Furnace
Control Board Relay Faults
A blower that runs nonstop after the call ends points to a stuck blower relay; an inducer that never starts with 24 volts present points to a failed inducer relay. Record the LED code before cutting power, then order the control board.
Flame Sensor Three-Attempt Lockout
If the burner lights and shuts off three times before lockout, oxide on the sensor rod is weakening the signal. Clean it with fine emery cloth and replace the sensor if the pattern returns.
Igniter and No-Fire Starts
When the furnace passes the pressure switch stage but never lights, inspect the RGDG-07EAUER igniter for cracks under direct light, since a cracked element can still measure normal resistance. Replace the igniter.
Inducer, Blower Motor, and Capacitor
Grinding during pre-purge means worn RGDG-07EAUER draft inducer motor bearings. For limit trips, test the blower run capacitor before replacing the blower motor.

Questions About the RGDG-07EAUER
Can I use an RGPH control board in this furnace?
No. The RGDG is a downflow model with its own blower timing and limit setup. Order the board listed for this model.
Why does my furnace light and shut off within seconds?
A contaminated flame sensor is the usual cause. Clean or replace it before testing the gas valve or control board.
Where can I find the parts list and manual?
Both are on this page. The diagram shows each part by position in the downflow cabinet.
Why does the inducer run but the burner never lights?
A pressure switch that will not close, a cracked igniter, or a board relay fault. Read the LED code to see which stage failed.
