Trane COL12849 Coil for 4-Way Reversing Valve Red 24V

The Trane COL12849 is a 24V coil specifically designed for Trane HVAC equipment, most commonly heat pumps. While the listed dimensions (1 x 1 x 1 inch) are likely placeholder values and the actual size will vary by model, its lightweight design (around 0.45 lbs) makes it manageable for servicing technicians. This coil works in conjunction with a 4-way reversing valve. When energized with 24V AC (compatible with both 50Hz and 60Hz electrical grids), the coil generates a magnetic field. This magnetic field triggers the movement of a valve spool inside the 4-way reversing valve, changing the direction of refrigerant flow. In a heat pump, this allows the system to switch between heating and cooling modes by reversing the direction heat is absorbed and released. Replacing a faulty coil with the Trane COL12849 ensures proper valve operation and efficient heat pump function.
