ICP NUGG075DF03 upflow gas furnace Parts

For the Icp upflow gas furnace model NUGG075DF03, the most common repairs are airflow and safety-related: replacing a dirty filter, fixing thermostat or wiring issues, cleaning ignition components, and addressing blower and limit-switch problems that cause short cycling or no heat.

Common repairs we see most often

• Air filter replacement (restricted airflow can overheat the furnace and trip safeties)
• Thermostat and low-voltage wiring fixes (loose connections, miswiring, weak batteries)
• Blower issues (no airflow, noisy operation, weak airflow)
• Capacitor replacement (motor hums, hard starting, intermittent blower)
• Limit switch troubleshooting (furnace starts then shuts off, frequent cycling)
• Electrical checks (blown fuse, tripped breaker, damaged wires)

Parts on this model that commonly relate to these repairs

If your symptoms point to the blower circuit or overheating shutdowns, these model-listed parts are common suspects:

Symptom	What it often points to	Example part for NUGG075DF03
Blower hums but won’t start or starts slowly	Weak run capacitor	Capacitor 12907
Loud vibration, rattling, or poor airflow	Worn or dirty blower wheel	Furnace blower fan wheel 600586
Furnace shuts off after a short run (short cycling)	Overheat condition or faulty limit	Limit switch 1013102

Quick checks before replacing parts

Turn off power to the furnace at the breaker before inspecting anything.

• Replace the air filter first; it is the fastest, most common fix.
• Confirm the thermostat is set to Heat and the temperature is set above room temperature.
• Check the furnace door is fully seated (many units have a door safety switch).
• Look for loose or burned wires; use our guide how to repair broken or damaged wires video if you find damage.
• If you suspect an electrical component, test safely with a meter using how to use a multimeter to test electrical parts video.

Why it matters

Most “no heat” calls trace back to airflow restriction or a safety shutdown. Fixing the root cause (filter, blower airflow, wiring) helps prevent repeated limit trips and reduces stress on the blower motor and controls.

For ordering, you can use the parts list for model NUGG075DF03 or search by model number on Sears PartsDirect.

For an Icp upflow gas furnace model NUGG075DF03, the cost to replace a furnace part depends on which component failed and whether you’re paying for labor. Parts on this model range from low-cost electrical items (like a capacitor) to high-cost components (like a blower motor).

Typical cost ranges (parts vs. total repair)

Below are practical ranges we see for furnace repairs; your total is usually parts + labor + service/diagnostic fee.

• Small electrical parts (capacitor, switches): usually the lowest cost
• Safety controls (limit switch): typically low to moderate cost
• Air-moving parts (blower wheel): moderate cost
• Major components (blower motor): highest cost
• Labor varies by access, wiring changes, and setup time

Example part type	Example from NUGG075DF03 parts list	Typical parts cost	Typical total installed cost
Capacitor	Capacitor 12907	Low	Low to moderate
Limit switch	Limit switch 1013102	Low to moderate	Moderate
Blower wheel	Blower wheel 1001184	Moderate	Moderate to higher
Blower motor	Furnace blower fan motor 613209	High	Higher

What drives the price up or down

These factors usually make the biggest difference in your final cost:

• Which part failed (motor and control boards cost more than switches and capacitors)
• Diagnostic time (pinpointing an intermittent issue can take longer)
• Labor complexity (tight cabinet space, seized set screws, rewiring)
• Related damage (overheating can take out a limit switch and stress the blower motor)
• After-repair setup (verifying temperature rise, airflow, and safe operation)

How to estimate your cost quickly

1. Identify the symptom (no heat, blower won’t run, short cycling, overheating).
2. Price the likely parts for NUGG075DF03 from the parts list on this page.
3. Add a typical service call plus labor time for replacement and testing.
4. If you’re ordering parts beyond what’s listed, search by model number on Sears PartsDirect.

Why it matters

Furnace parts pricing is all over the map because a “furnace part” can mean anything from a simple capacitor to a blower motor. Getting the right part for NUGG075DF03 helps avoid repeat service calls and protects key components like the heat exchanger and blower assembly.

Your Icp upflow gas furnace model number is on the furnace rating plate (data tag). On model NUGG075DF03, check inside the front access panel area near the burner compartment or blower compartment; the tag lists the model and serial number.

Where to look on the furnace

Turn off power to the furnace at the breaker, then remove the front panel(s) and look for a printed label.

• Inside the upper burner compartment door (often near the gas valve area)
• Inside the lower blower compartment door (near the blower housing)
• On a side wall of the cabinet, facing inward
• On the back of the removable access panel
• Occasionally on the exterior side of the cabinet near the electrical junction box

What the label looks like

Most Icp furnace data tags are a white or silver sticker or metal plate with multiple lines of text.

Label field	What it tells you	Why you need it
Model	The exact model (example: NUGG075DF03)	Ensures correct parts fit
Serial	Unit-specific serial number	Helps match production version
Input/BTU	Heating input rating	Confirms capacity
Electrical	Voltage and amperage	Helps with safe troubleshooting

Why it matters for parts and repairs

The exact model number (and sometimes the serial number) prevents ordering the wrong furnace parts, especially for electrical items like a furnace blower fan motor 613209 or safety controls such as a furnace temperature limit switch 1004304.

If the tag is missing or unreadable

• Check both access panels; some furnaces have two tags
• Look for a second sticker on the blower housing or inside cabinet wall
• Use the clearest number set; avoid copying patent numbers or certification codes
• If you are still unsure, use our guide: how to find your appliance model number (and what it means for parts)
