This manual-reset safety switch monitors burner flame rollout conditions. When abnormal heat or flame rollout is detected and the switch trips, the system shuts down and requires a manual reset before resuming operation. Licensed HVAC technicians install and service this component as part of routine furnace safety maintenance or diagnostic repair work.\u003c\/p\u003e\n\u003cp\u003eThis switch is suited for residential gas furnace applications where flame rollout protection is required. It mounts in the burner compartment area and responds to elevated temperatures caused by blocked flue passages, cracked heat exchangers, or other combustion airflow problems. When compatibility is confirmed by part number cross-reference, it serves as a direct OEM-style replacement in Carrier and related heating equipment lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e225 degrees F trip temperature for rollout detection\u003c\/li\u003e\n  \u003cli\u003eManual reset operation requires technician intervention after a trip event\u003c\/li\u003e\n  \u003cli\u003eSPST contact configuration interrupts the control circuit on trip\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for burner compartment mounting\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement design for reliable fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eListed in the input as a Carrier parts and accessories replacement.

Before replacing this switch, shut off power to the furnace at the disconnect or breaker and turn off the gas supply. Investigate the root cause of any rollout trip event before resetting or replacing the switch, as repeated tripping indicates an underlying combustion or venting problem that must be corrected. Follow applicable local codes and manufacturer service procedures during replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Temperature\u003c\/strong\u003e: 225 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Manual Reset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: Rollout and Limit Switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RCD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: hh22ha236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RCD","offers":[{"title":"Default Title","offer_id":51233626489138,"sku":"HH22HA236","price":113.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307626049.jpg?v=1780105028","url":"https:\/\/voomisupply.com\/products\/rcd-hh22ha236-rollout-limit-switch-225f-manual-reset","provider":"Voomi Supply","version":"1.0","type":"link"}
