This normally-closed thermal switch opens the control circuit if the furnace overheats — from a dirty filter, blocked return, or failing blower — then automatically resets once temperatures return to normal. A failed switch can cause nuisance shutdowns or, if stuck, compromise the furnace's overheat protection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20269903\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary limit \/ rollout auto-reset switch\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting bimetal)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GMPE075-3 gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM switch\u003c\/strong\u003e is calibrated to the exact trip and reset temperatures specified for the GMPE075 cabinet.
