Keep your Rheem RGPH-10AMER/Serial: EM heating through every season with genuine OEM replacement parts from Repair Clinic. The 10 code places this RGPH furnace in the 100,000 BTU input class, the largest common size in the series, and the EM serial prefix identifies its production range. Rheem and Ruud share one manufacturing platform, so equivalent Ruud models use the same service components. Parts replaced most often include the RGPH-10AMER/Serial: EM draft inducer motor, the flame sensor, the ignition parts, and the control board. Check your build on the RGPH-10AMER/Serial: EM parts list, then browse the full Rheem furnace parts catalog.
RGPH-10AMER/Serial: EM Furnace Details
This RGPH-10AMER/Serial: EM furnace is a non-condensing gas unit with a multi-speed PSC blower, so there is no condensate trap to service. At 100,000 BTU it moves more heat than the 07 size, and burners, orifices, and the blower are matched to that input. Its parts list includes a NOx insert retainer, which means some builds carry low NOx inserts in the burner area; reinstall them in the same position after burner service. The list also shows gas valves for both direct spark and hot surface ignition, so confirm your ignition type on the RGPH-10AMER/Serial: EM diagram. The RGPH-10AMER/Serial: EM manual documents the sequence of operation and LED fault codes. For RGPH-10AMER/Serial: EM repair steps, open the model troubleshooting page.
Most Replaced RGPH-10AMER/Serial: EM Furnace Parts
Ignition Source and No-Fire Starts
Read the fault code first. If the inducer runs and the pressure switch closes but the burner never lights, inspect the ignition source your diagram shows: hot surface elements crack with age, while spark electrodes fail from worn gaps or damaged leads. Order the RGPH-10AMER/Serial: EM igniter that matches your build from the ignition parts filter.
Flame Sensor Carbon Fouling
The RGPH-10AMER/Serial: EM flame sensor proves combustion through flame rectification. Carbon film on the rod reduces the signal, so the burner lights and shuts down within seconds. Clean the rod yearly with fine steel wool, and replace the flame sensor when cleaning no longer restores operation.
Draft Inducer and Pressure Switch Sequence
The inducer must prove draft before ignition proceeds. A motor that runs but never closes the pressure switch points to a restricted flue, cracked tubing, or a weak motor. Check the vent first, then confirm motor speed before replacing the inducer motor or the pressure switch.
Control Board Fault Codes
Board failures are less common than the faults they report. Replace the control board only after the ignition parts, flame sensor, inducer, and pressure switch test good, and match it to the RGPH-10AMER/Serial: EM serial range.

Rheem RGPH-10AMER Furnace FAQ
Why does my furnace start and then shut off after a few seconds?
A fouled flame sensor is the most common cause. Carbon on the rod weakens the signal, so the board closes the gas valve. Clean the rod, and replace the sensor if the symptom continues.
Is this a packaged unit?
No. It is cataloged as a gas furnace with its own blower. Parts for the burner, inducer, ignition, and controls are listed on this page by position in the cabinet.
What are the NOx inserts in the burner area?
They are inserts some builds use to lower nitrogen oxide emissions. If your furnace has them, reinstall them in the same position after burner or heat exchanger service.
Does the RGPH-10AMER/Serial: EM heat exchanger need inspection?
Have it inspected if the rollout switch trips, you see scorching near the burners, or limit trips continue with a clean filter and good airflow.
