One of the practical advantages of owning a Goodman furnace is parts availability. As the highest-volume residential HVAC brand in North America, Goodman parts are stocked at HVAC distributors, online retailers, and even some big-box stores across Minnesota. Here's a guide to finding the right parts at the right price.
How to Find Your Goodman Model and Part Numbers
Before ordering any replacement part, you need two things:
- Your furnace model number — found on the data label inside the lower access panel. Write it down exactly, including all letters and numbers. See our model number guide for help decoding it.
- The correct OEM part number — never order a part by description alone. "Pressure switch" describes hundreds of different parts with different ratings. You need the exact Goodman part number that fits your specific model.
To find the right part number: go to goodmanmfg.com → Parts & Literature → enter your model number → view the parts breakdown diagram for your unit.
Types of Goodman Parts
OEM (Original Equipment Manufacturer) Parts
Parts manufactured by or for Goodman/Daikin to the original specification. OEM parts are the safest choice for warranty-covered repairs — using non-OEM parts can potentially affect warranty coverage. For critical components (heat exchangers, control boards, gas valves), always use OEM.
Aftermarket Parts
Replacement parts made by third-party manufacturers to fit Goodman units. Quality varies significantly. For commodity parts like capacitors, contactors, and some motors, reputable aftermarket brands (Genteq, Packard, Mars) are often acceptable and less expensive. For safety-critical parts, stick with OEM.
OEM Equivalent / Cross-Reference Parts
Some parts (ignitors, flame sensors, pressure switches) are made by component suppliers who sell to multiple HVAC manufacturers. The same ignitor may carry both a Goodman part number and a generic part number — as long as the specifications match exactly, it's functionally equivalent.

Where to Buy Goodman Parts in Minnesota
HVAC Distributors (Best Source)
Johnstone Supply, Winsupply, Ferguson HVAC, and similar wholesale HVAC distributors stock Goodman OEM parts throughout Minnesota. Traditionally limited to contractors, many now sell to homeowners as well. Prices are typically 30–50% below retail. You need the exact part number.
Online Retailers
- RepairClinic.com — excellent parts lookup by model number, good stock levels, ships to Minnesota
- Repair Clinic and PartSelect both have model-specific part lookups
- Goodman direct parts (Daikin parts portal) — goodmanmfg.com links to authorized parts suppliers
- Amazon — good for commodity parts (capacitors, contactors, ignitors) but verify specifications carefully against your model
Local HVAC Supply Houses
Most metro Minnesota areas have local HVAC supply houses that stock common Goodman parts. Some will sell to homeowners with a valid model number. Faster than shipping for urgent repairs.
Parts to Keep On Hand
If you want to be prepared for the most common furnace failures — especially important in Minnesota where a furnace failure in January is a genuine emergency — consider keeping these on hand:
- Replacement air filter (in your furnace's size)
- Hot surface ignitor (model-specific — the most commonly failed part)
- Flame sensor rod
These three parts cover the majority of "furnace won't start" calls. Having them on hand means you can fix the most common failure in an hour rather than waiting for a service call or parts shipping.
When to Buy a New Furnace Instead of Parts
If your Goodman furnace is over 15 years old and you're ordering a significant component (control board, inducer motor, gas valve), compare the part cost to the cost of a new unit. At Furnace Direct, a new Goodman furnace starts at factory-direct pricing — sometimes not much more than a major repair on aging equipment, with a fresh 10-year warranty included.
