Get your Rheem RGRM-07EMAES/Serial: HJ back to reliable heat with genuine OEM replacement parts from Repair Clinic. The 07 code places this RGRM furnace in the 70,000 to 75,000 BTU input class (confirm the exact rating on the data plate), and the HJ serial prefix identifies its production range. Rheem and Ruud build on one platform, so equivalent Ruud models share service components. The parts replaced most often include the RGRM-07EMAES/Serial: HJ draft inducer motor, the pressure switch, the igniter, and the flame sensor. Confirm each part on the RGRM-07EMAES/Serial: HJ parts list, then browse the full Rheem furnace parts catalog.
Inside the RGRM-07EMAES/Serial: HJ Furnace
This RGRM-07EMAES/Serial: HJ furnace runs a staged sequence: the inducer starts and the pressure switch proves draft through the RGRM-07EMAES/Serial: HJ heat exchanger, the igniter heats, the gas valve opens, and the flame sensor confirms combustion. A lockout at any step produces an LED code, and reading it before replacing anything points straight to the failed stage. The HJ serial prefix matters mainly for control boards; igniters, flame sensors, and capacitors are rarely affected by serial range. The RGRM-07EMAES/Serial: HJ manual and RGRM-07EMAES/Serial: HJ diagram document wiring and the code chart. For RGRM-07EMAES/Serial: HJ repair steps, open the model troubleshooting page.
Most Replaced RGRM-07EMAES/Serial: HJ Furnace Parts
Draft Inducer Motor Wear
The inducer clears combustion gases before every cycle. Worn bearings cause humming or grinding at startup and slow the motor until the pressure switch never closes. Confirm full speed and a clear vent before replacing the inducer motor.
Pressure Switch Proving Faults
If the inducer runs normally but the furnace stops before ignition, check the switch tubing for cracks or water and the vent for blockage. Replace the pressure switch only when draft is good and the contacts stay open.
Igniter and No-Light Starts
When draft is proven but the burner never lights, inspect the RGRM-07EMAES/Serial: HJ igniter for cracks or uneven glow. Silicon based elements fail after years of heat cycles. Replace the igniter, touching only the ceramic base.
Flame Sensor and Brief Burner Runs
A burner that lights and shuts off within seconds points to an oxidized RGRM-07EMAES/Serial: HJ flame sensor. Clean the rod with fine steel wool, and replace the flame sensor if the lockouts continue.

Rheem RGRM-07EMAES Furnace FAQ
Why is my furnace not starting?
Read the LED code. The most common causes are a pressure switch that never closes, a cracked igniter, or a control board fault, so test them in that order.
What does the pressure switch prove on this Rheem furnace?
It confirms the inducer has created safe draft before the board allows ignition. A blocked vent, cracked tubing, or weak inducer keeps it open.
Does the HJ serial prefix change which parts fit?
It mainly affects control board ordering. Igniters, flame sensors, and capacitors are rarely affected, but always confirm against the listing for your model.
What are signs of a failing inducer motor?
Humming, grinding, or squealing at startup, slow spin-up, and pressure switch lockouts before the igniter energizes.
