This primary high-limit control continuously senses supply-air temperature over the heat exchanger and opens the circuit to shut off the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing unsafe operation. It is the furnace's main line of defense against restricted airflow from a dirty filter, blocked ducts, or a failing blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary automatic high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed; opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger overheat protection\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH950704CXAD and compatible furnace platforms\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is factory-calibrated to the exact trip and reset temperatures specified for your furnace, with a guaranteed mounting and terminal match.
