This microprocessor-based control is responsible for monitoring the outdoor coil temperature and compressor run time to determine when ice buildup needs to be removed. By efficiently switching the unit from heat pump mode to air conditioning mode (reversing the refrigerant flow) and activating supplemental heat, it ensures the outdoor coil remains clear for optimal heat transfer.\u003c\/p\u003e\n\u003cp\u003eAs an authentic OEM component (Catalog Number \u003cstrong\u003e16V38\u003c\/strong\u003e), the 100269-08 features factory-programmed timing intervals (typically selectable at 30, 60, or 90 minutes) and specific sensor calibrations required for your unit's safety and efficiency. Replacing a failed board with a genuine Lennox part ensures the defrost termination temperature is reached accurately, preventing unnecessary energy waste or \"freeze-up\" conditions that can lead to expensive compressor damage.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDemand \u0026amp; Timed Defrost:\u003c\/strong\u003e Manages the essential transition between heating and defrost modes based on factory-set logic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Reliability:\u003c\/strong\u003e Official Lennox replacement engineered for exact electrical compatibility and mounting hole alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagnostic LED Indicators:\u003c\/strong\u003e Features built-in status lights to assist technicians in identifying sensor faults or board errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Reversing Valve Control:\u003c\/strong\u003e Coordinates the reversing valve and outdoor fan motor operation during the defrost sequence.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 100269-08\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog #:\u003c\/strong\u003e 16V38\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Lennox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Defrost Control Board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTiming Intervals:\u003c\/strong\u003e Field-selectable (30, 60, 90 minutes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Standard spade terminals and multi-pin harness headers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGross Shipping Weight:\u003c\/strong\u003e 0.8 LB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e🛠️ HVAC Depot Pro Tip: The \"Sensor\" Trap\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eBefore replacing your 100269-08 defrost board, always test the outdoor coil thermistor (sensor). A very common \"false failure\" occurs when a sensor goes out of calibration or has a frayed wire, telling the board the coil is freezing when it isn't, or vice-versa. Use a multimeter to check the resistance (ohms) of the sensor against the manufacturer's temperature-resistance chart. If the sensor is bad, the new board won't fix the problem. Additionally, check for \"chattered\" contactor points, as electrical noise can sometimes scramble the logic on these sensitive microprocessors.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe 100269-08 is a direct OEM replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM \u0026amp; Catalog Numbers:\u003c\/strong\u003e 100269-08, 16V38, 59W38, 10026908, 59W3801.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Cross:\u003c\/strong\u003e Hamilton Standard \/ Lennox 100269 Series.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eNote: Use 'CTRL+F' to search for your specific model:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eLennox Elite \u0026amp; Merit Series (Specific Models):\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e13HPX-024-230-01, 13HPX-030-230-01, 13HPX-036-230-01\u003c\/li\u003e\n\u003cli\u003e14HPX-024-230-01, 14HPX-030-230-01, 14HPX-036-230-01\u003c\/li\u003e\n\u003cli\u003eXP13-024-230-01, XP13-030-230-01, XP13-036-230-01\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003eAlso compatible with corresponding Armstrong Air and Ducane models.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":52929224933739,"sku":"100269-08","price":215.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/16v38-1.jpg?v=1771610946","url":"https:\/\/tophvacparts.com\/products\/lennox-p-n-100269-08-oem-heat-pump-defrost-control-board-p-n-16v38","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
