Hey there, Mike from The Furnace Outlet here!
If you’ve just snagged the Goodman GR9S960803BN furnace and are staring at it wondering “Where do I even start?”, don’t sweat it. I’ve been in the trenches with these units, and I’m going to walk you through installation, troubleshooting, and a few pro hacks to make this beast run smoothly all winter long. ❄️🔥
🛠️ Let's Get Started!

🏗️ Installation Steps
1. Preparation & Safety
-
Check your location: Make sure your furnace space meets local codes and is free of debris.
-
Ventilation & clearance: Maintain proper distances around the unit for airflow and safety. The Department of Energy explains why clearance matters.
-
Shut off gas and power before touching anything.
2. Positioning the Furnace
-
Upflow Installation: Level it and secure it on the floor.
-
Horizontal Installation: Use the drain kit and make sure condensate can flow downhill.
Quick tip: You want the furnace positioned for easy access to the control panel — nothing worse than a furnace you can’t reach.
3. Ductwork Connections
-
Attach supply and return ducts, ensuring airtight seals.
-
Use proper-size plenums for smooth airflow.
-
Pro advice: Energy Star recommends sealing ducts to improve efficiency — not just for comfort, but for your wallet too.
4. Gas Line Hookup
-
Shut off the gas supply completely.
-
Apply thread sealant to connections to avoid leaks.
-
Pressure-test the line. If you’re unsure, check out Goodman’s official installation manual for detailed diagrams.
Safety first — gas is no joke. Always double-check your connections.
5. Electrical Connections
-
Connect to a dedicated 115V power source.
-
Wire the thermostat according to the manual.
-
Ensure proper grounding to prevent hazards.
-
Tip: Even if you know wiring, check Electrical Safety Foundation resources for a refresher on safe connections.
6. Condensate Drainage
-
Connect drain line to a proper drain.
-
Ensure a slight downward slope so water doesn’t back up.
Horizontal installs are trickier here — don’t skimp on slope. Trust me, you don’t want water pooling in your furnace.
🧪 Startup & Post-Installation Checks
-
Power on the unit and gas supply.
-
Set thermostat to the desired temperature.
-
Check for a steady blue flame (indicator of good combustion).
-
Confirm airflow feels consistent in vents.
Fun tip: Run your furnace through a full cycle and listen for unusual noises. A quick check now saves big headaches later.
🛠️ Troubleshooting Common Issues
Even top-tier furnaces have hiccups. Here’s how to tackle the usual suspects:
1. No Heat
-
Thermostat set correctly?
-
Circuit breaker tripped?
-
Gas supply okay?
2. Furnace Won’t Start
-
Power to the furnace?
-
Flame sensor dirty? Clean it.
-
Control board errors? Reference your manual.
3. Uneven Heating
-
Dirty filters — replace them.
-
Leaky or obstructed ducts.
-
Blower motor issues — inspect or replace.
🧠 Pro Tips from Mike
-
Always schedule a maintenance check before winter hits.
-
Label wires during installation — future troubleshooting will thank you.
-
Keep the furnace area clean and clear. Even a small pile of dust can impact efficiency.
