This board manages the front-panel controls, display, and input signals that allow occupants and technicians to set operating modes, temperature setpoints, and fan speeds. It acts as the communication bridge between the user-facing controls and the main control circuitry within the PTAC unit. HVAC technicians install this board when the existing UI fails to respond, displays errors, or loses button functionality, restoring full operational control to the unit.\u003c\/p\u003e\u003cp\u003eThis board is intended for use in PTAC systems, which are commonly found in hotels, motels, assisted living facilities, and multi-unit residential buildings. The WP26X31393 replaces a failed or damaged user interface board in applicable LENNOX PTAC installations. Installation typically occurs during a service call when front-panel unresponsiveness, blank displays, or erratic mode behavior is diagnosed as a board-level fault rather than a wiring or sensor issue.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDirect-replacement PCBA for the PTAC user interface position\u003c\/li\u003e\n\u003cli\u003eControls display output, mode selection, and temperature setpoint input\u003c\/li\u003e\n\u003cli\u003eInterfaces with main PTAC control board to relay occupant commands\u003c\/li\u003e\n\u003cli\u003eDesigned for commercial and multi-unit residential PTAC applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement user interface control board for compatible LENNOX PTAC units.

Disconnect power to the PTAC unit at the circuit breaker before removing the front panel or accessing internal boards. Handle the PCB carefully to avoid static discharge damage to onboard components. Confirm all ribbon cable and connector seating after installation before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Printed Circuit Board Assembly (PCBA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: User Interface Control Board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Packaged Terminal Air Conditioner (PTAC)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LENNOX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: WP26X31393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENNOX","offers":[{"title":"Default Title","offer_id":67593419227442,"sku":"WP26X31393","price":41.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a442f3b2eb4fbfa6ae0396e2e09e0247.jpg?v=1790422355","url":"https:\/\/voomisupply.com\/products\/lennox-wp26x31393-ptac-user-interface-board","provider":"Voomi Supply","version":"1.0","type":"link"}
