Trane Parts

Trane Furnace and HVAC Parts

Trane builds equipment to last, and when it does need repair, genuine OEM parts are one reliable way to maintain that reliability. Whether you're replacing an igniter, control board, or inducer motor, Repair Clinic carries the exact Trane parts your system needs. Trane's XC95m, XR95, XR80, and XV80 furnaces are engineered for precision — aftermarket parts don't match the exact specifications Trane controls require.

Find the right part fast by entering your Trane model number above. We stock igniters (both SiC and SiN carbide types), CNT control boards, pressure switches, flame sensors, limit switches, capacitors, gas valves, blower motors, and inducer motor assemblies. If your Trane isn't heating, producing error codes, or running intermittently, the parts you need are here.

• Gas oven igniter won't glow: Trane hot surface igniters (SiC or SiN) — verify type for your model before ordering
• Draft inducer motor is noisy or won't start: Inducer motor assembly with wheel and housing — pressure switch errors often follow motor failure
• Furnace trips pressure switch repeatedly: Pressure switch or inducer motor — blocked drain line should be ruled out first
• Flame sensor glows but igniter shuts off after 3 seconds: Flame sensor (rod type) — clean with fine steel wool first, but often requires replacement
• Control board shows error codes or no display: CNT control board (Trane proprietary) — model-specific, cannot be programmed aftermarket

Trane HVAC Parts: Frequently Asked Questions

What's the difference between SiC and SiN igniters on Trane furnaces?

Trane uses two igniter types: silicon carbide (SiC) and silicon nitride (SiN). Your model number determines which one is correct — they are not interchangeable. SiC igniters operate at around 1,700°C and are found on older Trane models. SiN igniters run hotter and are more durable on newer systems. Always verify your model number before ordering an igniter to avoid an incompatible part.

Can I use an aftermarket control board instead of a Trane CNT board?

No. Trane's CNT control boards are proprietary and model-specific. They contain manufacturer-coded logic that cannot be replicated or programmed by aftermarket manufacturers. Using a non-OEM board will result in communication failures, incorrect heating cycles, and potential safety shutdowns. Always order the CNT board that matches your exact Trane model.

How do I find my Trane model number for parts ordering?

Your Trane model number is on the data plate, usually located on the front or side of the furnace cabinet. It starts with "XC" (Signature), "XR" (mid-tier), or "XV" (variable-speed) followed by numbers like 95, 80, or 96. For heat pumps, look for "HST" or "HPA" prefixes. Enter the full model number in the search box on this page — Repair Clinic will show you all compatible parts and sub-assemblies for your specific unit.

My Trane furnace keeps shutting off after the igniter glows. What should I replace first?

In order of likelihood: (1) Flame sensor — clean it first with fine steel wool; if that doesn't work, replace it. (2) Gas valve — verify gas pressure is reaching the valve before replacing. (3) Control board — if the board isn't sending the flame-proven signal to hold the gas valve open, the furnace will shut down as a safety measure. Use your model number to order the exact flame sensor or control board Trane engineered for your system.

For a Trane heat pump or central air conditioner, check the nameplate on the outdoor cabinet or inside its access panel. Copy the complete model number, including letters and numbers, exactly as printed. Type it into our model number lookup and the catalog narrows to parts made for your unit, across every associated part category. Matching the full equipment model helps identify the correct parts quickly and cuts down on compatibility mistakes.
