This secondary safety switch provides an extra layer of over-temperature protection beyond the main limit — typically guarding the blower compartment or a secondary heat zone. When it senses excess heat it interrupts the control circuit, then re-closes automatically once temperatures return to normal. If your furnace intermittently loses heat and then recovers on its own, a weak auxiliary limit is a likely culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary over-temperature limit switch\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (self-resetting bimetal)\u003c\/li\u003e\n\u003cli\u003eFunction: Secondary safety cutout for the control circuit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WGGE4330A070MAB and compatible units\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20269903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch guarantees the correct trip and reset temperatures for this furnace platform.
