Frequently Asked Questions About Rheem Parts

What's the difference between Rheem and Ruud parts?

Rheem and Ruud are made by the same manufacturer — Rheem Manufacturing Company. Most parts are identical or cross-compatible, but the model numbers may differ slightly. Always look up your exact model number (found on the data plate) to confirm the correct part. Repair Clinic's lookup tool will show you Rheem and Ruud equivalents side by side.

Why won't my Rheem water heater pilot light stay lit?

The thermocouple is the #1 culprit — it's a safety sensor that proves the pilot flame is burning. When it fails, the gas valve shuts off automatically. A thermocouple is a $10 to $20 part and a 15-minute fix. Gas valve assembly problems are the second most common cause. If the thermocouple is clean but won't hold the pilot, test the gas valve next.

How do I find my Rheem model number for furnace or water heater parts?

Look for the white or yellow data plate on your unit. Furnace plates are usually on the side of the cabinet or inside the blower compartment. Water heater plates are on the upper tank. The model number is several digits or alphanumeric (like R97V or RU101). Enter it in the Repair Clinic lookup box — we'll show you compatible parts and confirm exact fit before you order.

Can I use aftermarket furnace boards and water heater parts on my Rheem unit?

OEM Rheem parts are always the safest choice, especially for control boards and safety parts like gas valves and pressure switches. Aftermarket boards often don't have the exact programming for your model, and non-OEM gas valves may not open at the correct pressure. Stick with genuine Rheem parts to maintain model-specific fit and performance and ensure safety compliance.

Rheem Equipment Model Number: Where to Look

On Rheem equipment, start with the white or yellow data plate. For furnaces, check the side of the cabinet or the blower compartment door. On water heaters, the plate is usually on the upper tank, while air conditioners and heat pumps typically have a nameplate on the outdoor cabinet. The model number may include letters, numbers, and slashes, so copy it exactly, including any suffixes. Enter that number in the search bar to narrow the catalog to parts made for your specific Rheem unit, across every applicable part category. Using the complete model number helps separate similar equipment versions and gives you a faster, more accurate match, so you order with confidence knowing the fit is right.
