Trane COL12849 Coil

The Trane COL12849 is a rugged 24VAC reversing valve solenoid coil engineered for precise refrigerant flow control in high-performance heat pump systems. This red 24V solenoid coil is the critical component responsible for energizing the pilot valve within a 4-way reversing valve, facilitating the shift between heating and cooling cycles. High-duty cycle performance is maintained through its OEM technical specifications, ensuring the magnetic field strength is sufficient to shift the valve spool even under high differential pressures.

As a veteran-grade HVAC replacement part, the COL12849 provides a seamless drop-in fit for older or failed solenoids. It serves as the direct replacement for COL13233, EF19ZG239, and 1172619. Whether you are servicing a residential split system or a light commercial pack unit, utilizing this genuine Trane heat pump coil ensures electrical compatibility with the existing 24V control circuit, preventing common chatter or engagement issues associated with generic aftermarket alternatives.

• Direct OEM Compatibility: Engineered as the specific replacement for COL13233 and EF19ZG239 to ensure exact electrical resistance and physical fit.
• Optimal Heat Pump Control: Provides reliable actuation for 4-way reversing valve assemblies, critical for maintaining system mode switching.
• Durable Solenoid Design: The red 24vac coil is built to withstand high-ambient temperatures found in outdoor condenser units without winding degradation.
• Simplified Field Replacement: Standardized lead connections allow for fast integration into existing Trane and American Standard wiring harnesses.

How do I verify if my reversing valve coil is failing?
Test for 24VAC at the coil leads when the thermostat calls for a mode change (typically the "O" or "B" terminal). If voltage is present but the valve does not click or shift, check the ohm resistance of the coil; an open circuit or significant deviation from OEM specs indicates a failed solenoid.

Is this coil compatible with both heating-active and cooling-active valves?
Yes, the COL12849 is designed to work with standard 24VAC 4-way valves used across the Trane and American Standard lineup, provided the mechanical valve body matches the coil’s mounting stem.

Does the color of the coil matter during replacement?
In many Trane systems, the red coil signifies the 24VAC voltage rating. Always confirm the voltage on the existing part's label to ensure compatibility with your transformer's output.
