How Goodman Products Fail – and How We Fix Them

Goodman builds a solid mid-range furnace. After years of servicing them across Hempstead, we see the same failure patterns repeat. Here’s what actually goes wrong, including the ones Goodman’s own site won’t tell you about.

• Ignitor failure on GMSS96 and GMES96 single-stage models. These furnaces use a silicon nitride hot-surface ignitor that gets brittle after 5 – 7 years of cycling. When it cracks, the gas valve never gets the signal to open. You’ll hear the draft inducer motor spin up, then nothing. We typically replace the ignitor in under an hour with an OEM-spec part and verify ignition sequence before we leave.
• Pressure switch trips on the GMVC96 two-stage line. In Hempstead homes with older venting, especially around the colonial-era blocks near Hofstra, we see flue restrictions from rust flakes or insect nests cause false pressure switch faults. The furnace locks out even when nothing is mechanically broken. We test actual flue draft with a manometer before condemning the switch – a step that separates a real diagnosis from a parts shotgun.
• Blower motor capacitor failure on the GMS8 80% line. A dead capacitor means the blower hums but won’t spin. This presents as no airflow with the burners on, which leads to high-limit trips. The capacitor is a $60 – $120 fix on most calls. We test the microfarad reading, not just look for a swollen can, because capacitors degrade below spec long before they visibly bulge.
• Heat exchanger rust-out on units 12+ years old. This is the expensive one. Goodman’s aluminum tubular exchangers hold up better than older crimped steel designs, but Hempstead’s coastal air pushes furnace duty cycles high from November through March. When we find cracks or corrosion, we show you the scope on a borescope camera – not a vague warning, a picture. Then you decide: repair under any remaining parts warranty or replace.
• Condensate drainage clogs on 90%+ AFUE condensing models like the GMEC96. These units produce acidic condensate that grows slime in the drain trap during shoulder seasons. The furnace shuts down on a blocked-drain pressure switch code, and the fix is a thorough trap flush. We also check drain pitch because floors in older Hempstead basements are rarely level, and a sloped drain line quietly undermines the repair.

Our Goodman Furnace Repair Process

Every Goodman repair we do in Hempstead follows the same sequence. No shortcuts, no surprises.

1. 1
   You call, we answer. A live person takes your call 24/7 and books a window that works. You’ll know the technician’s name before they arrive.
2. 2
   Arrival and initial diagnostics. We confirm the symptom you described, then run our own sequence-of-operation test to isolate the failing component. Goodman boards store fault codes; we read them, but we don’t treat a code as a diagnosis by itself.
3. 3
   Parts decision. Where it matters – ignitors, flame sensors, gas valves, pressure switches – we use OEM or OEM-spec Goodman parts. For wear items like capacitors, we use quality aftermarket equivalents when they meet or exceed spec, and we tell you which you’re getting and why.
4. 4
   Written price before work starts. Once we’ve identified the failure, you get a fixed price in writing. No hourly meter, no “it got complicated.” The number you approve is the number you pay.
5. 5
   The repair and full-system test. We do the work, then run the furnace through a complete heating cycle. Gas pressure, flame signal, temperature rise, and safety limit operation all get checked.
6. 6
   Cleanup, invoice, guarantee. We leave the mechanical room cleaner than we found it. You get the written guarantee for the repair – one full year. If it fails in that time, we return at no charge.
