ICP NUG5075BFB2 furnace Parts

Bad burners in your Icp NUG5075BFB2 furnace show up as flame and ignition problems: flames that are yellow/orange instead of mostly blue, delayed ignition, rumbling, soot, or burners that do not light evenly across the row. These symptoms point to rust, clogged burner ports, or damaged burner surfaces.

• Flame color: mostly steady blue is normal; persistent yellow/orange suggests dirty burners or poor combustion.
• Carryover: one burner lights but the next one does not (restricted crossover/ports).
• Delayed ignition: a “whoosh” or bang at light-off.
• Soot or scorching: black soot near the burner area or around the furnace cabinet.
• Short cycling: burners light, then shut down quickly (often tied to flame sensing or overheating).
• Unusual odors: sharp, hot, or “burnt dust” smells that persist after a few minutes of run time.

Some symptoms that look like “bad burners” are actually caused by ignition, airflow, or safety controls.

If inspection shows physical damage (heavy rust, cracks, warped metal) or the burner will not clean up, replacement is the fix.

• Furnace burner 1008724 (burner body that shapes and stabilizes the flame)
• Furnace pilot igniter and sensor 1009524 (ignition and flame proving)
• Limit switch 1013102 (shuts burners down if the furnace overheats)

Burners that do not light cleanly can reduce heat output, increase soot, and cause nuisance shutdowns. Catching burner restriction early also helps protect ignition parts, the blower system, and temperature safety controls.

Replacing a furnace burner in your Icp NUG5075BFB2 typically costs $150 to $900+ total, depending on whether you replace a single burner or multiple burners, plus labor and a safety checkout. The burner part itself for this model is the furnace burner 1008724.

Costs vary by region and furnace condition, but most burner replacements fall into these buckets:

• Burner part: commonly $50 to $250 per burner (model-specific pricing varies)
• Labor: commonly $100 to $500 (diagnosis, removal, install, combustion check)
• Service call/diagnostic (if charged separately): commonly $75 to $150
• Additional parts (only if needed): igniter, sensor, gasket, or a limit switch

These are the most common reasons a “burner replacement” turns into a larger repair:

• Burner mounting hardware is rusted or seized
• Burners are damaged due to heavy corrosion or flame rollout history
• The ignition system is weak (hot surface igniter or pilot/ignition sensor issues)
• Airflow or overheating problems trigger safety shutdowns (limit switch trips)
• A combustion blower seal or gasket is leaking

If you’re also chasing ignition or safety shutdown symptoms, parts that often come up on this model include the furnace pilot igniter and sensor 1009524 and the limit switch 1013102.

A burner is part of the combustion system. Correct flame carryover, proper gas-to-air mix, and a final safety check help your furnace heat reliably and avoid nuisance shutdowns.

To avoid mismatches, we recommend:

• Confirm the full model number: NUG5075BFB2
• Match the burner by the part ID and description
• Compare your old burner’s shape and mounting points before ordering
• Order from the parts list for this model, or search by model on Sears PartsDirect

For an Icp furnace model NUG5075BFB2, the cost to replace a furnace part depends on which component failed and whether you’re replacing it yourself or paying for a service call. On this model, common replacement parts range from a low-cost electrical component to higher-cost assemblies.

Here are realistic parts-only ranges for this furnace type, using examples from the NUG5075BFB2 parts list.

• Small electrical parts (capacitors, switches): $5 to $50
• Safety controls (limit switches): $20 to $60
• Ignition parts (igniter, flame sensor style parts): $150 to $500
• Air-moving parts (blower wheel, blower assembly): $150 to $350+
• Gas/valve components: $300 to $900+

Parts are only one piece of the total. Installed cost is driven by:

• Service call/diagnostic fee (often a flat trip charge)
• Time on site (simple electrical parts vs. major disassembly)
• Access (tight closet installs, attic installs)
• Setup and testing (combustion checks, temperature rise, safety verification)
• After-hours or emergency scheduling

Replacing the wrong part is the fastest way to overspend on a furnace repair. A quick diagnosis (checking airflow, ignition sequence, and safety switches) helps you target the correct component and avoid repeat breakdowns.

To keep costs under control, match the part to your exact model number NUG5075BFB2 and compare the part name and ID before ordering. You can order from the parts list for this model, or search by model number on Sears PartsDirect.

If your Icp furnace model NUG5075BFB2 won’t ignite, gas is usually being blocked by a closed shutoff, an ignition failure, or a safety circuit (limit or switch) stopping the gas valve from opening. Start with power, thermostat, and airflow checks, then inspect ignition and gas-valve components.

• Set thermostat to Heat; raise setpoint 5 to 10 degrees.
• Confirm the furnace service switch is on; reset a tripped breaker.
• Verify the gas shutoff valve is fully open (handle parallel to pipe).
• Replace a clogged air filter; restricted airflow can open the limit.
• Make sure the blower door is seated so the door switch is engaged.

The control board only opens the gas valve after it “proves” safe operation.

• Ignition component failure: A bad igniter or pilot assembly prevents lighting; see furnace pilot igniter and sensor 1009524 or igniter 1149856.
• Limit circuit open: Overheating or airflow restriction can open the limit; see limit switch 1013102.
• Gas valve issue: The valve can fail or not receive the open signal; see valve 1170430.

These checks focus on the safety sequence that prevents raw gas release and overheating; correcting airflow, ignition, or valve control restores reliable heat.

The most expensive furnace repair is replacing the heat exchanger because it involves major disassembly and significant labor. On an Icp NUG5075BFB2 furnace, other high-cost repairs often involve major airflow or ignition components, depending on what fails and how hard it is to access.

• Heat exchanger replacement
• Blower system repairs (motor, wheel, or full blower assembly)
• Gas control and safety circuit repairs (valves, switches, relays)
• Ignition repairs (igniter, flame sensor, pilot/ignition assemblies)
• Electrical diagnosis time (intermittent faults, wiring, connections)

These parts are on the NUG5075BFB2 parts list and are often tied to higher-labor repairs or no-heat complaints:

• Furnace blower assembly 1013833 (moves heated air through the ductwork)
• Furnace blower fan wheel 600587 (air-moving wheel inside the blower)
• Furnace pilot igniter and sensor 1009524 (ignition and flame sensing)
• Igniter 1149856 (ignition component)
• Furnace fan control relay 1170063 (controls blower operation)

The highest bills usually come from repairs that combine a costly core component with time-consuming access and safety checks. Identifying the failing system first helps avoid replacing the wrong part.

• Shut off electrical power at the breaker before opening panels
• Confirm the thermostat is calling for heat
• Replace a dirty filter and clear blocked returns (overheating can mimic failures)
• Inspect wiring terminals for looseness or heat damage
• Test electrical parts correctly (see how to use a multimeter to test electrical parts video)
