Suburban Furnace Core | 2615A | RP-40P | 40K BTU | NT-40P 120V

Restore your Suburban NT-40P Park Model furnace with the Suburban Furnace Core (Part #2615A / RP-40P). Genuine Suburban OEM furnace core (heat exchanger + burner + blower assembly) — the complete internal working unit that fits into your existing furnace cabinet. 40,000 BTU, 120V Park Model, quiet operation, incredibly compact and lightweight design. Cabinet assembly NOT included.

What This Does

The furnace core is the complete internal working assembly of your Suburban furnace — heat exchanger, burner, blower, and gas train pre-assembled as a single unit that slides into the existing furnace cabinet. When the internal components fail but the cabinet is still serviceable, this core lets you rebuild the furnace without replacing the entire unit.

⭐ Primary Fitment — Suburban NT-40P (120V Park Model)

Direct replacement core for Suburban NT-40P Park Model furnaces — the 120V AC variant designed for Park Model installations. 40,000 BTU output.

⚠️ 120V Park Model — NOT for 12V Coach Furnaces

Critical compatibility note: this core is engineered specifically for 120V Park Model NT-40P furnaces. If your furnace is a 12V DC coach furnace (not a 120V Park Model), this is NOT the correct core.

12V DC Coach Furnace Core Instead?

If your furnace is a 12V coach model (not a 120V Park Model), see:

• Suburban 40K BTU Furnace Core 2614A / RP-40N — for NT-40SP 12V series (9.5A)
• Suburban 30K BTU Furnace Core 2613A / RP-30N — for NT-30SP 12V series (also fits NT-24SP/NT-34SP with BTU change)

SF-Series Instead?

If your furnace is a Suburban SF-Series (not NT-Series), see the Suburban 25K BTU Furnace Core 2608A / RP-30FQ — for SF-25F/25FQ/30F/30FQ/FQ (2555A/2558A) furnaces.

⭐ Ideal Replacement for Obsolete Competitive Furnaces

With multiple side OR bottom duct options, Suburban furnace cores are easy to install and make an ideal replacement for obsolete competitive furnaces. If your original furnace brand is no longer supported, this Suburban core can often be adapted with the existing cabinet or a Suburban cabinet.

⚠️ Professional Installation Required

Furnace core installation involves LP gas connections, 120V AC electrical wiring, and proper cabinet alignment. Because of the safety-critical nature of furnace gas systems and 120V AC power connections, installation should be performed by a qualified RV service technician.
