Keep your Nordyne MGHA 056ABFC-05 heating reliably with genuine OEM replacement parts from Repair Clinic. The 056 code identifies a 56,000 BTU input class, and the -05 suffix marks a production revision of this Nordyne MGHA gas furnace. Nordyne builds for several labels, including Gibson and Intertherm, so the same components are sold under those names. Parts replaced most often include the pressure switch, the blower motor, the MGHA 056ABFC-05 flame sensor, and the igniter. Confirm each part on the MGHA 056ABFC-05 parts list, then shop all Nordyne furnace parts.
MGHA 056ABFC-05 Furnace Details
The -05 revision suffix matters most for control boards and harnesses, which can change between production runs; ignition and sensing parts are usually shared with adjacent revisions. Combustion runs in a fixed order: the MGHA 056ABFC-05 draft inducer motor proves draft through the pressure switch, the igniter heats, the gas valve opens, and the flame sensor confirms combustion. The blower then moves heated air off the MGHA 056ABFC-05 heat exchanger, and the limit switch shuts the burner down if airflow falls short. The MGHA 056ABFC-05 manual and MGHA 056ABFC-05 diagram show component positions and fault codes. For MGHA 056ABFC-05 repair steps, open the model troubleshooting page.
Most Replaced Parts on the MGHA 056ABFC-05 Furnace
Pressure Switch and Draft Proving
When the furnace locks out before the igniter stage, the pressure switch has not seen enough draft. Check the vent for blockage, the tubing for cracks or water, and the inducer for full speed before condemning the switch. Replace the pressure switch when draft is good and the contacts stay open.
Blower Motor and Run Capacitor
Weak airflow and limit trips often trace to the capacitor rather than the motor. Test the run capacitor and replace it if it reads more than 5 to 10% below its rated value. Replace the blower motor only when the capacitor is good.
Flame Sensor and Shutdown After Ignition
A burner that lights and shuts off within seconds points to a dirty flame sensor that cannot confirm the flame. Clean the rod, and replace the flame sensor if the pattern continues.
Igniter and No-Start Conditions
Read the board code first. If draft is proven but the burner never lights, inspect the MGHA 056ABFC-05 igniter for cracks or weak glow and replace the igniter, holding it only by the ceramic base.

Nordyne MGHA 056ABFC-05 FAQ
Why won’t my furnace turn on?
Read the board fault code. The usual causes are a pressure switch that never closes, a cracked igniter, or a control board fault, so test them in that order.
What does the -05 at the end of the model mean?
It is a production revision of the MGHA 056ABFC-05. It mainly affects control boards and harnesses. Igniters and flame sensors are usually shared with nearby revisions.
Why does the furnace shut off right after ignition?
A dirty or failing flame sensor cannot confirm the flame, so the board closes the gas valve. Clean the rod and replace it if lockouts continue.
Which MGHA 056ABFC-05 parts are replaced most often?
The pressure switch, blower motor and capacitor, flame sensor, igniter, and control board. Each is shown by position on the diagrams tab.
