Restore full heating output from your Rheem RGPH-07AUER/Serial: EM with genuine OEM replacement parts from Repair Clinic. The 07 code places this RGPH furnace in the 70,000 to 75,000 BTU input class (confirm the exact rating on the data plate), and the EM serial prefix identifies its production range. Rheem and Ruud build on one platform, so the Ruud UGPH-07AUER shares its service components. Parts most often replaced include the draft inducer motor, the flame sensor, the ignition parts, and the control board. Start with the RGPH-07AUER/Serial: EM parts list, then browse the full Rheem furnace parts catalog.
Inside the RGPH-07AUER/Serial: EM Furnace
This is a non-condensing gas furnace with a multi-speed PSC blower, so diagnosis is more direct than on a condensing unit: there is no condensate trap to clear and no PVC vent to inspect. The serial prefix matters mainly for control boards, so confirm the board against the EM listing; ignition and capacitor parts are rarely affected by serial range. The parts list for this model includes gas valves for both direct spark and hot surface ignition, which means the ignition source can differ by build. Check the RGPH-07AUER/Serial: EM diagram before ordering an igniter. The RGPH-07AUER/Serial: EM manual on the diagrams tab covers the sequence of operation and LED fault codes.

Most Replaced RGPH-07AUER/Serial: EM Furnace Parts
Draft Inducer Motor and Pressure Switch Proving
The RGPH-07AUER/Serial: EM draft inducer motor clears the heat exchanger and vents combustion gases before ignition, and the pressure switch must prove that draft. Worn bearings make the motor hum or grind at startup, then stall and trigger a pressure lockout. If the motor runs but the switch stays open, inspect the vent and tubing before replacing either part. Replacement inducer motors are listed here.
Flame Sensor Signal Loss
The RGPH-07AUER/Serial: EM flame sensor is a single rod that sits in the burner flame and proves combustion to the board. Oxidation raises its resistance, so the furnace lights, heats briefly, and shuts off within seconds. Cleaning with fine steel wool often restores the signal; a cracked or pitted rod requires a new flame sensor.
Igniter or Spark Ignition Faults
Read the fault code first so you know whether ignition, draft, or flame proving failed. If the inducer runs and the switch closes but the burner never lights, inspect the ignition source shown on your diagram: hot surface elements crack with age, while spark electrodes fail from worn gaps or damaged leads. Order the RGPH-07AUER/Serial: EM igniter that matches your build from the ignition parts filter.
Rollout Switch Trips and Heat Exchanger Checks
The manual reset rollout switch opens when flame escapes the burner area. Never simply reset it repeatedly: a trip points to a blocked flue, a restricted RGPH-07AUER/Serial: EM heat exchanger, or an inducer problem. Correct the root cause first, then replace the switch if it fails a continuity test.

Rheem RGPH-07AUER Furnace FAQ
Why does this furnace light and then shut off within seconds?
A weak or oxidized flame sensor is the usual cause. The board cannot confirm the flame, so it closes the gas valve. Clean or replace the sensor rod before condemning the gas valve or control board.
Is the Rheem RGPH-07AUER the same as the Ruud UGPH-07AUER?
They are built on the same Rheem and Ruud platform and share service components. Serial prefixes differ by production range, so confirm control boards against the listing for your exact serial range.
Does the EM serial prefix change which parts fit?
It mainly affects control board ordering. Flame sensors, inducers, and capacitors are rarely affected, but the ignition source can differ by build, so check the diagram before ordering an igniter.
How do I read the fault code?
Count the LED flashes in the repeating pattern and match the count to the chart inside the access panel or in the manual. The code tells you which stage of the sequence failed before you replace anything.
