As the primary distribution hub for the system’s electrical operations, this board manages the communication between the thermostat and the indoor blower motor, ensuring that heating, cooling, and fan-only cycles execute with perfect timing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Performance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating on 24V control power\u003c\/strong\u003e, this board manages high-voltage transitions for the blower motor and electric heat strips. Being a \u003cstrong\u003eGenuine OEM\u003c\/strong\u003e component ensures that the time-delay profiles (blower on\/off delays) match the factory specifications of your unit. This precision prevents \"cold air blasts\" at the start of a heating cycle and ensures the heat exchanger or heat strips are properly cooled at the end of a cycle, protecting the system from high-limit trips and thermal stress.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Blower Timing:\u003c\/strong\u003e Manages the ramp-up and shut-down delays for the indoor fan to maximize comfort and system efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Reliability \u0026amp; Fitment:\u003c\/strong\u003e Guaranteed to match original mounting footprints and multi-pin harness connectors for a \"plug-and-play\" installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Circuit Monitoring:\u003c\/strong\u003e Integrated logic monitors safety limits and heat strip sequencers to prevent equipment overheating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect-Fit Design:\u003c\/strong\u003e Features factory-correct terminal labeling, eliminating the guesswork associated with universal \"one-size-fits-all\" control modules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 47-100436-05 (Replaces 47-100436-01, 47-100436-04)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Rheem \/ Ruud (PROTECH™ Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Air Handler Control Board \/ Blower Logic Board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 24V (Control)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Approx. 5\" x 4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Standard plastic standoff mounts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 0.85 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e🛠️ HVAC Depot Pro Tip: The Label \u0026amp; Snap Technique\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBefore removing the old 47-100436-05\u003c\/strong\u003e board, take a high-resolution photo of all wiring connections. Air handler boards often have multiple speed taps (Black, Blue, Red wires) that must be returned to their specific \"Heat\" or \"Cool\" terminals to maintain proper airflow. Also, ensure the power is disconnected at the breaker; even a small 24V spark from a thermostat wire can \"pop\" the fuse or damage the microprocessor on the new board during installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe 47-100436-05 is a direct OEM replacement for the following part numbers:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e 47-100436-05, 4710043605, 47-100436-01, 47-100436-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoard ID:\u003c\/strong\u003e 1012-920, 1012-920A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRH1P Series:\u003c\/strong\u003e RH1P, RH1T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRH2P Series:\u003c\/strong\u003e RH2P, RH2T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRBHP Series:\u003c\/strong\u003e RBHP-17, RBHP-21, RBHP-24, RBHP-25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRHLP Series:\u003c\/strong\u003e RHLP-PW, RHLP-HM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Air Handlers:\u003c\/strong\u003e Compatible with most Rheem\/Ruud PSC-motor based air handler units.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Rheem","offers":[{"title":"Default Title","offer_id":52451516547435,"sku":"662766361285","price":142.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/47-100436-0.jpg?v=1766082149","url":"https:\/\/tophvacparts.com\/products\/protech-47-100436-05-genuine-oem-air-handler-control-board","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
