<h2>Arcoaire Furnace Parts</h2><p>Arcoaire furnaces are built on proven ICP engineering — the same platform as Heil, Tempstar, and Comfortmaker. When your heating system needs repair, OEM Arcoaire parts ensure the right fit and performance. The most common furnace failures we see are hot surface igniters, draft inducer motors, and pressure switches. A worn igniter that glows orange but won't hold a flame, or an inducer motor that won't kick the cycle off — these are almost always the culprit when your furnace clicks on but produces no heat.</p><p>Repair Clinic carries the full range of Arcoaire furnace parts, from control boards to limit switches to gas valves. Because Arcoaire shares the ICP family platform, many parts cross-reference to Heil and Tempstar models — but always verify your exact Arcoaire model number to ensure you get the correct part. Every Arcoaire furnace is engineered to specific pressures and voltages, and OEM parts maintain those tolerances.</p><ul><li><strong>Hot surface igniters:</strong> Won't glow, glows dim, or ignites then shuts off within seconds</li><li><strong>Draft inducer motors:</strong> Won't run, runs weak, or trips pressure switch repeatedly</li><li><strong>Pressure switches:</strong> Furnace clicks but won't start, or starts then immediately shuts down</li><li><strong>Flame sensors:</strong> Igniter lights but gas valve won't open, or system cycles on and off</li><li><strong>Control boards and limit switches:</strong> Error codes, no response, or overheating shutdowns</li></ul><p>Find your Arcoaire model number on the rating plate inside the furnace cabinet — it usually starts with AUH or similar. <a href="https://www.repairclinic.com/Shop-For-Parts/a36b389/Arcoaire-Furnace-Parts">Browse Arcoaire furnace parts by model</a> to locate exact replacements for igniters, motors, valves, and boards. Same-day shipping available on most in-stock items.</p>

<h2>Arcoaire Furnace FAQs</h2><h3>Why does my Arcoaire furnace igniter keep going out after it lights?</h3><p>A weakening igniter often glows but can't sustain the temperature needed to keep the gas valve open. The igniter draws current to trigger the valve; as it ages, it loses heat output. You'll see the flame start, then the valve snaps shut. Silicon carbide (SiC) and silicon nitride (SiN) igniters are the two main types — verify which one your model uses before ordering. Cleaning the igniter with fine steel wool sometimes buys time, but replacement is the permanent fix.</p><h3>What does the draft inducer motor do, and why is it failing?</h3><p>The draft inducer motor runs first in the heating cycle — it pulls air and exhaust gases out of the heat exchanger and up the vent pipe, creating a vacuum. This vacuum is monitored by the pressure switch, which signals the rest of the cycle to begin. If the inducer fails, won't start, or runs weakly, the pressure switch never closes and the furnace shuts down. Common causes are a blocked vent (leaves, nests, ice), cracked drain hose, or motor bearing failure. Check airflow first — if the vent is clear, the inducer motor or pressure switch is next.</p><h3>Can I replace just the Arcoaire pressure switch, or do I need a technician?</h3><p>A pressure switch is one of the simplest furnace repairs you can make yourself — it's a small part with just two wires and typically one screw. However, before replacing it, verify that the vent line is clear, the inducer motor is running, and the drain hose isn't cracked. A blocked vent or weak inducer will trip a good switch. If those check out, the switch itself has failed and needs replacement. Make sure you order the exact pressure switch for your Arcoaire model — pressure ranges vary by furnace type.</p><h3>How do I find the right Arcoaire control board replacement?</h3><p>Arcoaire furnace control boards (IFC boards) are model-specific and cannot be interchanged. The board controls gas valve timing, igniter power, blower motor speed, and safety shutdowns. Error codes that flash on the LED (typically a series of blinks) tell you which part has failed. Enter your full Arcoaire model number, including any suffix letters, into Repair Clinic's model lookup — the search will show you the exact board and any error code chart for your unit. Never assume two similar boards are the same; a mismatch will cause starting failures or error codes.</p>

<h2>Arcoaire Furnace Model Number: Where to Look</h2>
<p>Arcoaire prints the model number on the rating plate inside the furnace cabinet, often near the front access panel or blower compartment door. Turn off power to the furnace, remove the access panel, and copy the complete model number, including every letter and suffix. You may see a code beginning with AUH or a similar series designation. Enter that number into the model number search to pull up the parts matched to your unit across the full Arcoaire furnace catalog. Matching by the complete model helps account for differences in controls, motors, igniters, valves, and other associated parts. That means fewer wrong orders and a faster repair.</p>
