Trane OEM Parts

AC Not Cooling — Capacitor or Contactor

Trane condensers (XR13, XR14, XR15, XV18, XV20i series) use the same failure-prone components as all residential AC: the run capacitor fails most often, followed by the contactor. Trane units typically use a 40/5 or 45/5 MFD 440V dual run capacitor. The Trane-specific part number is on the capacitor label, but any capacitor matching the MFD and voltage will work.

Furnace Flashing Red Light

Trane and American Standard furnaces share the same integrated furnace control (IFC) board with a diagnostic LED. Common codes: 2 flashes = system lockout (recycle power to reset), 3 flashes = pressure switch error (check drain trap and vent), 5 flashes = flame sensed without gas valve call (dangerous — shut off gas immediately), 9 flashes = reversed line/neutral polarity. Check the error code chart above for the complete list.

Furnace Ignition Problems

Trane furnaces (XR80, XR95, XV80, XV95, S9V2, XC95m) use silicon nitride hot surface igniters — more durable than silicon carbide but still a wear item. Average lifespan is 4-6 years. Symptoms: inducer runs but igniter never glows (cracked igniter), or igniter glows but gas doesn't flow (bad gas valve or control board issue). Shop Trane igniters →

Trane vs American Standard — Same Parts?

Yes. Trane and American Standard are the same company (Trane Technologies). They use identical internal components — same compressors, control boards, motors, and part numbers. An American Standard part will fit the equivalent Trane model and vice versa. The only differences are cosmetic (cabinet color, badge).
