Gibson furnaces, built by Nordyne, are engineered for reliable heating in homes across North America. When your Gibson furnace stops heating or starts acting up, the culprit is usually one of a handful of high-failure parts. Repair Clinic stocks genuine OEM Gibson furnace parts — the same parts your furnace was built with — so you get the exact fit and performance your system needs.
Whether you're replacing a hot surface igniter, pressure switch, inducer motor, or control board, having the right part on hand means you can get heat back fast. Use your Gibson model number to find the exact replacement parts for your unit, and get same-day shipping on most orders.
The hot surface igniter is the #1 Gibson furnace failure. When the igniter glows orange but won't stay on, or doesn't glow at all, it's time to replace it. It's a straightforward 20-minute repair that restores your heat immediately. Always verify whether your model uses a silicon carbide (SiC) or silicon nitride (SiN) igniter — the types are not interchangeable.
Your Gibson model number is on a metal nameplate attached to the furnace cabinet, usually near the blower compartment on the left or right side. Look for a number starting with "G" followed by numbers and letters (e.g., G1M, G2M). Write down the complete model number and enter it into our parts lookup — we'll show you the exact parts your furnace needs.
If your furnace motor runs but the burner won't ignite, start with the pressure switch and draft inducer motor. A blocked vent, cracked hose, or failed inducer will trip the pressure switch and prevent ignition. If those test okay, the hot surface igniter is next. If the furnace doesn't run at all, check the limit switch reset button on the furnace cabinet — it may have been tripped by a blocked filter or poor airflow.
Yes — Gibson and Intertherm are both Nordyne brands and share most furnace parts. However, always confirm your exact model number before ordering, because some parts (especially control boards and igniters) can vary between model years. Our parts lookup cross-references all Nordyne brands to give you the correct fit.

On Gibson furnaces, look for the model number on the metal nameplate attached to the cabinet, typically near the blower compartment on the left or right side. The label may be visible after removing the front access panel, so switch off power before opening the cabinet and record the complete model number, including letters and numbers. Type it into our model number lookup and the catalog narrows to parts made for your unit. This model number applies to the whole furnace, not just one replacement part. You can then review the full Gibson furnace parts selection with a much better fit match. That means fewer wrong orders and a faster repair.

Repair Clinic's online repair library gives you the tools to diagnose and fix your Gibson Furnace without a service call.
