The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light-blue body) is a genuine OEM thermal safety switch for the ACSH960704CXAA 96% AFUE gas furnace. This auxiliary limit monitors temperature in a specific zone of the furnace cabinet and opens the control circuit if it detects overheating — typically caused by restricted airflow, a dirty filter, or a failing blower. The color coding (light blue) indicates its specific trip temperature rating, so matching the exact part is critical for proper protection.
Limit switches are color-coded to precise temperature set points. Installing a generic switch — or the wrong color — risks either nuisance trips or, worse, failure to cut off during a genuine overheat event. The OEM 0130F00038 guarantees the correct trip temperature and mounting footprint for safe operation.
Easy (2/5). Two wire terminals and a mounting screw or two. Disconnect power first and photograph wiring before removal. Because this is a safety component, have a licensed HVAC technician verify the underlying cause of any trip before returning the furnace to service.
