Goodman 10123519 Manual Reset Limit Switch

The Goodman 10123519 is a genuine OEM manual-reset high-limit safety switch for the GKS91155DXAA gas furnace. This normally-closed thermal switch opens the ignition/gas-valve circuit if it senses an overheat condition — typically from a blocked flue, dirty filter, or failed blower. Because it is a manual reset device, it must be pressed back in after a trip, alerting the homeowner that a fault occurred rather than silently cycling.

Specifications

  • Part Number: 10123519
  • Type: Manual reset high-limit / rollout safety switch
  • Contacts: Normally closed, opens on over-temperature
  • Brand: Goodman (Amana / Janitrol compatible)
  • Equipment: High-efficiency gas furnace
  • Primary Fit: GKS91155DXAA

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the exact trip temperature specified for this furnace. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect the heat exchanger. As a life-safety component, the OEM part is strongly recommended.

Installation Difficulty

Easy (2/5). Shut off power and gas, remove two mounting screws, transfer the two spade connectors, and reinstall. About 15 minutes. Important: if the switch keeps tripping, diagnose the underlying overheat cause before returning the furnace to service.

Match the part number to your furnace nameplate before ordering — trip temperatures vary by model.

Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this limit switch compatible with Bryant or Payne too?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman limit switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
