Unlike an auto-reset limit, this switch must be manually reset after it trips — a deliberate design that forces a technician to inspect the furnace after an overheat event rather than let it cycle back on unattended. It opens the circuit when the heat exchanger or plenum temperature exceeds a safe threshold, shutting down the burners to protect the furnace and home.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eType: High-limit switch, manual reset\u003c\/li\u003e\n\u003cli\u003eReset: Push-button manual reset (non-self-restoring)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH950905DXAD and compatible gas furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-temperature overheat cutout\u003c\/li\u003e\n\u003cli\u003eMounting: Snap-disc \/ bracket, model-specific location\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eManual-reset limits are calibrated to a specific trip temperature matched to this furnace's heat exchanger. Substituting a generic switch risks the wrong set point or an auto-reset design that defeats the safety intent. This OEM part provides the exact trip temperature, reset mechanism, and terminal layout the furnace requires — no guesswork on a safety-critical component.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy\u003c\/strong\u003e — typically 15–25 minutes. Disconnect power, remove the panel, photograph and detach the wiring, unscrew the old switch, and mount the replacement in the same orientation. Reconnect the leads, press the reset button, restore power, and confirm normal operation. If the new switch trips, investigate the underlying cause — restricted airflow, dirty filter, or a failing blower — before returning the unit to service. Always de-energize the furnace first.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058067161459,"sku":"GOODMAN-10048","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-gch950905dxad-10123517","provider":"National HVAC Parts","version":"1.0","type":"link"}
