Get dependable heating from your Goodman GMPN080-4 furnace with genuine OEM replacement parts from Repair Clinic. The GMPN080-4 is an 80,000 BTU single-stage upflow gas furnace built on a four-ton blower platform, marketed as a Northern-climate variant of the GMP080 series with airflow calibrations suited to colder regional installations; the GMPN designation indicates a Northern-climate variant, and most service parts are shared between GMP080 and GMPN080-4. Goodman, Amana, and Daikin are the same manufacturing family sharing this platform. Parts most frequently replaced include the hot surface igniter B1401018S/0230K00001, control board B1809913S, flame sensor 0130F00010, inducer motor B2833001S, and blower motor B1340020S.

Goodman GMPN080-4: 80,000 BTU Northern-Climate Four-Ton Platform, GMP080 Shared Components, and Longer-Vent Inducer Context
The GMPN080-4 shares most of its service components with the GMP080-4 and GMP100-4 siblings on the same Goodman platform. The key differences lie in the blower motor speed tap configuration and airflow-specific calibrations for Northern-climate use. Northern-climate installations with longer venting runs place additional back-pressure on the inducer motor B2833001S, which can accelerate bearing wear compared to short-run installations; inspect the inducer for bearing noise annually in installations with vent runs exceeding 20 feet.

Most Replaced Parts on the Goodman GMPN080-4
Hot Surface Igniter B1401018S / 0230K00001
The GMPN080-4 originally shipped with the B1401018S silicon carbide igniter. Goodman’s current OEM replacement is the 0230K00001 silicon nitride mini igniter, rated seven times more durable than the carbide original. A failed igniter causes the board to time out without a confirmed flame and lock out the furnace; handle the element only by its ceramic base during installation to avoid thermal hot spots from skin oils. Browse Goodman furnace igniter parts.
GMPN080-4 Control Board B1809913S
The B1809913S is the 9-pin HSI control board managing ignition, blower delays, and safety switch monitoring on the GMPN080-4. The LED flash pattern stores the most recent fault in a two-digit blink code; read and document the code before replacing any component. A three-flash code indicating ignition failure points to the igniter or flame sensor, not the board, in the majority of GMPN080-4 service calls. Browse Goodman furnace control board parts.
GMPN080-4 Draft Inducer Motor B2833001S
Goodman part B2833001S is the draft inducer motor for the GMPN080-4 platform, sized to draw combustion gases through the heat exchanger before the main burner ignites. Bearing wear presents as a grinding sound during the pre-purge phase; Northern-climate installations with longer venting runs place additional back-pressure on the inducer and can accelerate bearing wear. Browse Goodman furnace inducer motor parts.
GMPN080-4 Blower Motor B1340020S and Capacitor CAP100000370VAS
The B1340020S is a 1/2 HP, 1075 RPM, 3-speed PSC motor serving the GMPN080-4 four-ton blower assembly. The run capacitor for this motor is CAP100000370VAS. A capacitor that has drifted outside its rated microfarad value causes the motor to start slowly or run at reduced speed, triggering limit switch trips from insufficient airflow. Always test the capacitor before ordering a replacement motor. Browse Goodman furnace blower motor parts.
GMPN080-4 Flame Sensor 0130F00010
The flame sensor 0130F00010 confirms sustained combustion to the B1809913S control board. Surface oxidation on the rod is the most common cause of short-cycling lockouts; cleaning the rod with fine steel wool can provide temporary relief, but a worn or corroded rod should be replaced for lasting results.

Goodman GMPN080-4 Furnace Parts FAQ
What is the control board part number for the Goodman GMPN080-4?
The control board for the GMPN080-4 is Goodman part B1809913S, the HSI board with a 9-pin connector. It manages ignition sequencing, blower timing, and safety switch monitoring. Before replacing it, read the LED fault code to confirm the fault points to the board itself rather than a sensor, igniter, or pressure switch that the board is reporting as failed.
What igniter fits the Goodman GMPN080-4 furnace?
The original igniter is Goodman part B1401018S, a silicon carbide hot surface igniter. The current OEM replacement is 0230K00001, a silicon nitride mini igniter that Goodman released as the upgraded successor. Silicon nitride is significantly more durable than silicon carbide and is the recommended replacement for any GMP or GMPN platform furnace today.
What is the difference between the Goodman GMP080 and GMPN080-4?
The GMPN designation indicates a Northern-climate variant of the GMP080 platform, typically incorporating airflow or venting calibrations suited to colder regional installation requirements. Most service parts including igniter B1401018S, flame sensor 0130F00010, control board B1809913S, and inducer motor B2833001S are shared between GMP080 and GMPN080-4. Always verify with the full model number from your data plate before ordering blower or cabinet-specific components.
What causes the Goodman GMPN080-4 to short cycle?
Short cycling on the GMPN080-4, where the furnace runs for only a few minutes before shutting off, is almost always caused by the primary limit switch opening due to heat exchanger overtemperature. The root cause is restricted airflow, most commonly a dirty air filter, a clogged blower wheel, closed supply registers, or a degraded blower motor run capacitor CAP100000370VAS. Resolve the airflow restriction before replacing the limit switch.
