Heil Furnace Parts & Repair Help

Heil furnaces are built on the ICP platform, sharing parts and engineering with Tempstar, Comfortmaker, Arcoaire, and Grandaire. When your Heil furnace stops heating, won't ignite, or cycles on and off, the fix usually comes down to one of a few high-failure parts. We carry OEM Heil parts that match your exact model — from hot surface igniters to draft inducer motors to control boards.

The most common Heil furnace repair starts with the hot surface igniter. If you see the igniter glow orange but then fade out, or it doesn't glow at all, that ceramic part has failed. Draft inducer motors, pressure switches, and limit switches round out the next tier of frequent repairs. Heil furnace parts are often cross-compatible with ICP family brands, but always verify your model number for the correct igniter type, board revision, and motor spec.

• Igniter glows then goes out, or won't glow: Hot surface igniter failure — verify SiC vs. SiN type for your model
• Furnace starts then pressure switch trips immediately: Draft inducer motor failure or blocked/cracked pressure switch hose
• Burner lights but furnace cycles off within seconds: Flame sensor dirty or failed; try cleaning first, then replace if needed
• No heat, no response when thermostat calls for heat: Control board (IFC) failure or blown transformer — use model number for exact board
• High-limit switch keeps tripping or won't reset: Limit switch failure or airflow restriction — check filter and ductwork first

Heil Furnace Parts FAQ

What's the difference between Heil, Tempstar, and Comfortmaker furnaces?

All three are ICP brands built on the same platform — they share most parts and control board designs. A Heil igniter often works in a Tempstar furnace, and vice versa. The key difference is the model number and board revision. Always enter your full model number to get the exact OEM part, because board codes and igniter types can vary by product line and year.

My Heil furnace pressure switch keeps tripping. Is it the switch itself?

Not always. The pressure switch monitors draft (negative pressure) during the heating cycle. If it trips immediately, check for a blocked inducer drain tube, cracked pressure line hose, or weak draft inducer motor first. If the motor is running and the hoses are clear, then the pressure switch itself has likely failed — it's a $30 to $60 part and a straightforward replacement.

How do I know if I need a new hot surface igniter or just a cleaning?

A visual inspection helps. If the igniter element is visibly cracked or has a dark burn spot, replace it. If it looks intact but won't glow, or glows very faintly, measure the resistance with a multimeter — most Heil igniters should read between 50 to 200 ohms when cold. Out of range = replace. When in doubt, a new OEM igniter ($20 to $40) is cheaper than a service call and will restore reliable starts.

Where do I find my Heil furnace model number?

The model number is typically on a silver or white label on the furnace blower compartment or side panel. It starts with letters like HG, HP, or HE, followed by numbers. Enter this full model number into our lookup tool to confirm the correct igniter type (SiC or SiN), control board revision, inducer motor spec, and any other OEM parts you need. This step takes 30 seconds and ensures you get the right part the first time.
