The Goodman 10123535 Manual Reset Limit Switch (Red) is a genuine OEM high-limit safety control for the GMH950905DXAA 95% AFUE gas furnace. The red-body switch denotes its specific trip temperature and mounting location within the furnace, providing over-temperature protection by cutting the gas valve if the unit exceeds safe limits. Its manual-reset design requires a technician to intervene after a fault, ensuring the underlying cause — restricted airflow, a failed blower, or a clogged filter — is addressed rather than masked.

Specifications

  • Part type: Manual reset high-limit switch (red body)
  • OEM part number: 10123535
  • Reset: Manual (push-button)
  • Compatible model: Goodman GMH950905DXAA
  • Function: Over-temperature safety cutoff

OEM vs. Generic

The red-coded 10123535 is calibrated to a distinct set point from similar switches (such as the 10123533). Ordering the genuine OEM part guarantees the correct trip temperature and prevents mixing up positions during a repair. Generic substitutes risk incorrect calibration on a life-safety component.

Installation Difficulty: Moderate

Disconnect power and gas, remove the access panel, transfer the two spade-terminal leads, and mount the switch to its bracket. Hand tools and a continuity meter recommended. Verify correct red vs. non-red switch placement per the wiring diagram.
