Rheem and Ruud furnaces have the highest flame sensor replacement rate of any major brand in our data. The flame sensor on Rheem Classic, Classic Plus, and Prestige models accumulates carbon quickly due to sensor positioning. The symptom: furnace lights, runs 3-7 seconds, then shuts off. Clean with fine sandpaper or replace — it's a $15-$20 part. Rheem part 62-24164-01 is the most common. Shop Ruud flame sensors →
Rheem/Ruud condensers (RA13, RA14AZ, RA16AZ series) use standard dual run capacitors — typically 40/5 or 45/5 MFD 440V. The outdoor unit hums but doesn't start when the capacitor fails. These are identical to capacitors used in other brands — match the MFD and voltage rating. Shop Ruud capacitors →
Rheem furnaces use the 62-104058-02 and similar integrated furnace control boards. LED diagnostic codes: 2 blinks = pressure switch stuck open, 3 blinks = draft pressure error, 4 blinks = high-limit open (check filter), 7 blinks = gas valve circuit error. Power surges are the leading cause of board failure — a whole-house surge protector is cheap insurance. Shop Ruud control boards →
Identical. Rheem and Ruud are the same manufacturer (Rheem Manufacturing). They share every internal component — same compressor, same board, same sensors, same part numbers. Rheem is sold through Rheem dealers; Ruud through independent distributors. The equipment is the same.
Ruud has served the professional HVAC contractor market since 1897 and shares its engineering foundation with Rheem. Most Ruud OEM part numbers cross-reference directly to Rheem equivalents. Our Ruud inventory covers residential and commercial packaged units - RKRL, RKMA, RAPM series included - with legacy coverage back to 1990.
