This board controls the outdoor coil defrost cycle by monitoring temperature inputs, sequencing the compressor and outdoor fan, and initiating defrost only when required to prevent ice accumulation. Its rigid PCB construction ensures stable operation, accurate timing, and long‑term reliability in residential HVAC applications. This is the correct replacement when systems experience coil freeze‑ups, short‑cycling, or inconsistent defrost behavior due to a failing control board.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe \u003cstrong\u003eS1‑031‑03754‑000\u003c\/strong\u003e is used in select Johnson Controls heat pump systems, including:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eYork heat pump units\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eColeman heat pump units\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eLuxaire heat pump units\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eIt supports timed\/temperature‑initiated defrost cycles and is used to correct issues such as coil freeze‑ups, short‑cycling, or improper defrost operation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCommon equivalent or superseded numbers associated with this board include:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e031‑03754‑000\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eS103103754000\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e03103754000\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eOEM York\/Coleman\/Luxaire defrost control equivalents\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eThis board is part of the same York\/Coleman\/Luxaire defrost‑control family as:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eS1‑031‑01971‑000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eS1‑031‑01975‑000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eS1‑031‑01976‑000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eS1‑031‑03004‑000\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eS1‑031‑03498‑001 (demand‑defrost)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eS1‑031‑03754‑000\u003c\/strong\u003e (this listing)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Neuco","offers":[{"title":"Default Title","offer_id":43041995751490,"sku":null,"price":169.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1071\/8320\/files\/Screenshot2026-03-02130958.png?v=1772482250","url":"https:\/\/hvacpartstore.com\/products\/s1-031-03754-000-york-board-circuit-defrost-respac","provider":"HVACpartstore","version":"1.0","type":"link"}
