WeatherKing Furnace Parts

Weatherking Furnace Parts and Repair Help

Weatherking furnaces are built by the York family of brands and share engineering with Luxaire and Airtemp models. Whether your Weatherking is refusing to ignite, won't hold a flame, or has stopped producing heat entirely, the issue usually traces back to one of a handful of high-failure parts. Getting the exact OEM part for your model number is critical — Weatherking furnaces demand precise matches for igniters, control boards, and motor assemblies.

The most common Weatherking furnace repairs involve the hot surface igniter (the glow bar that lights your burners), the draft inducer motor (the fan that creates safe combustion pressure), and the flame sensor (the safety device that confirms ignition). Less common but equally important are pressure switches, limit switches, and main control boards. Enter your Weatherking model number below to find the exact furnace parts your system needs.

• No heat, igniter glows orange then goes dark: Hot surface igniter failure — silicon carbide type; verify model-specific part number
• Furnace starts then shuts down after a few seconds: Flame sensor clogged or failed; try cleaning with fine steel wool first
• Furnace won't start, pressure switch error: Draft inducer motor stuck or failed; also check vent for blockage
• Thermostat calls for heat but furnace is dead: Main control board or transformer failure; verify 24V control voltage at board
• Blower runs but no heat: Gas valve, limit switch, or igniter — heat exchanger may have cracked (serious issue)

Weatherking Furnace Parts: Common Questions

What's the difference between Weatherking, York, Luxaire, and Airtemp furnaces?

Weatherking is a York family brand — all four brands (York, Weatherking, Luxaire, and Airtemp) share the same manufacturing platform and often interchange parts. The control boards, igniters, inducer motors, and limit switches from a York furnace will frequently fit a Weatherking model of the same vintage and stage configuration. However, part numbers can differ slightly, so always use your exact Weatherking model number to confirm the correct OEM part. Johnson Controls owns this family, and cross-brand compatibility is one of their strengths.

How do I find my Weatherking furnace model number?

The model number is on a metal plate, usually on the side or front of the furnace cabinet. It starts with a letter code (often 'W' for Weatherking) followed by five to seven digits. Write it down exactly as it appears — including any dashes or suffixes — and enter it into Repair Clinic's parts finder. The model number tells you the furnace stage (single or two-stage), whether it has communicating controls, and which igniter type your furnace uses. Getting the model number right is the fastest path to the correct part.

My Weatherking furnace pressure switch keeps tripping. Is it the switch or something else?

A tripped pressure switch is usually a symptom, not the root cause. Before you replace the switch, check three things: (1) Is the vent or vent hose blocked or crimped? (2) Is the drain line for the inducer motor's condensation clogged? (3) Is the draft inducer motor actually spinning when the furnace fires up? If those are clear and the switch still trips on every cycle, the pressure switch itself has likely failed. Pressure switches are inexpensive ($20 to $40), and Repair Clinic carries the OEM Weatherking switch for your model.

What's the most common Weatherking furnace repair, and how much should I expect to spend?

The hot surface igniter is the #1 repair — it's also one of the least expensive ($30 to $60 for the part itself). The igniter is a ceramic bar that glows red-hot to ignite the gas burners. After 10 to 15 years of heating cycles, it weakens and stops reaching the ignition temperature. You'll see it glow orange instead of bright red, and the furnace won't light. A homeowner with basic skills can replace it in 20 minutes. If your furnace is making noise or won't stop running, the inducer motor or blower motor is likely next ($80 to $150 for the part). Main control boards are the most expensive repair ($200 to $400), but they fail less frequently.

WeatherKing Furnace Model Number: Where to Look

WeatherKing typically places the furnace model number on a metal rating plate attached to the side or front of the cabinet. Check behind the front access panel or on the blower compartment door if it is not visible from outside. The label may also list the serial number, so copy the model number exactly, including letters, numbers, and any suffixes. Enter that code in the Repair Clinic search bar to narrow the complete WeatherKing furnace parts catalog to parts that fit your specific unit. This model lookup accounts for differences between furnace series and configurations, helping you avoid ordering by appearance alone. It is the quickest way to confirm compatibility before you order.
