York S1-025-32816-000 Control Module

The York S1-025-32816-000 is a critical Fan Timer Control Module engineered specifically for residential and light commercial air handlers and furnaces. As a Genuine OEM York Replacement Part, it provides the precise sequencing required to manage blower motor delay timings, ensuring optimal heat exchanger dissipation and preventing coil freeze-ups in cooling modes. This solid-state HVAC control board manages the 120V or 240V blower motor circuits while interfacing with the 24V thermostat signals. Weighing 0.60 lbs, the S1-025-32816-000 is designed for direct-drop installation into existing cabinet footprints, maintaining original equipment efficiency standards. Technicians should utilize this module when diagnosing irregular fan cycling or failures in the blower relay circuit to restore factory-specified environmental control and airflow timing within the air stream.

Technical Application Benefits:

• OEM Compatibility: Precision-matched for York equipment, eliminating the mounting and wiring complexities associated with universal furnace fan timers.
• Optimized Cycle Timing: Regulates fan-on and fan-off delays to maximize SENSIBLE heat recovery and improve overall SEER/EER ratings.
• Reliable Logic Control: Industrial-grade circuitry designed to withstand the thermal stresses found in furnace vestibules and air handler compartments.
• Direct Replacement: Simplifies field service by utilizing standard terminal designations for York S1-025-32816-000 installations.

Common Technical Questions:

Is the S1-025-32816-000 compatible with variable speed motors?
This specific fan timer control is primarily designed for single-stage and multi-speed PSC (Permanent Split Capacitor) motors. Always verify your motor type and wiring schematic before installation.

What are the symptoms of a failing York fan timer control?
Common failure points include the blower failing to engage after a call for heat/cool, the fan running continuously regardless of thermostat setting, or intermittent relay chattering during the sequence of operation.

Are the terminal connections labeled for field wiring?
Yes, the board features standard spade terminals clearly marked for low-voltage (thermostat) and line-voltage (blower/power) connections to ensure an accurate York control module swap.
