Source1 33109150000 Simplicity 1A Control Board 2 4 Stage Replacement S1-33109150000

Product Description

The SOURCE1 33109150000 is a Simplicity 1A control board designed for 2 and 4 stage HVAC systems. It serves as a direct OEM replacement for York units and compatible equipment. Control boards are the brain of an HVAC system. They receive signals from the thermostat, process those signals, and tell the system when to heat, cool, or shut down. Without a functioning control board, the unit cannot regulate temperature or protect itself from faults. This board uses built-in algorithms to manage system settings automatically. It adjusts operation based on demand, whether the system is running in 2 stage or 4 stage mode. That flexibility makes it suitable for a range of residential and light commercial applications. HVAC technicians rely on OEM control boards like this one to restore full system function without risking warranty issues. Using a genuine OEM part means the board is built to the exact electrical and communication specifications of the original. There is no need to modify wiring or reprogram settings. The board fits several popular York units including XYE05A2C1AA3A111A2, V33AC04A2KAABL0001, and F2FP048H06, among others. Always verify the model number before ordering to confirm compatibility. The board measures 7.7 inches in length, 6.15 inches in width, and 2.8 inches in height. It weighs 0.665 pounds, making it easy to handle during installation. HVAC service professionals working on York gas furnaces, heat pumps, or air handlers will find this control board straightforward to install as a like-for-like swap. It supports staged heating and cooling control, which is essential for efficient operation in multi-stage comfort systems.
