Heatcraft Refrigeration 21340101 Defrost Timer
The Heatcraft 21340101 Defrost Timer, also identified as the DTSX240, is a heavy-duty mechanical control engineered for demanding commercial refrigeration and freezer applications. This 230V defrost timer features a robust 40A capacity, making it a standard OEM replacement part for Heatcraft, Bohn, and Larkin walk-in units. Built for high-amperage loads, it provides precise timing for electric defrost cycles, preventing evaporator ice accumulation that compromises system efficiency. The DTSX240 model is designed with industrial-grade switching components to withstand the frequent cycling found in walk-in cooler refrigeration environments. When a technician replaces a failed refrigeration defrost control, this unit serves as the reliable choice for ensuring proper defrost cycle duration and frequency, maintaining critical temperature stability. Its integration into the system’s electrical rack simplifies HVACR troubleshooting and ensures long-term operational consistency for commercial walk-in boxes.
Key Benefits:
- High Amperage Rating: The 40-amp contact rating ensures high-capacity switching for multiple heaters without the need for additional contactors.
- Direct OEM Compatibility: Engineered specifically for Heatcraft refrigeration systems, ensuring a precise fit and simplified wiring in Bohn and Chandler evaporators.
- Rugged Mechanical Reliability: The synchronous motor and heavy-duty gear train eliminate the failure points often found in lower-grade electronic timers under high-moisture conditions.
- Precise Defrost Management: Allows for accurate scheduling of defrost intervals to maintain optimal airflow and prevent coil freeze-ups.
Common Questions:
Is the Heatcraft 21340101 compatible with 120V systems?
No, this specific model is designed for 230V refrigeration systems. Using this on a 120V circuit will cause the clock motor to fail or run improperly. Always verify your supply voltage before installation.
Can I use the DTSX240 to replace a standard 8145-20 timer?
While they perform similar functions, the Heatcraft 21340101 (DTSX240) is the specific Heatcraft OEM replacement. Always verify mounting dimensions and terminal configurations, as this unit is built to specific manufacturer cabinet tolerances.
What is the maximum number of defrost cycles per day?
This mechanical timer supports multiple pins, typically allowing for 1 to 6 cycles per 24-hour period, depending on the specific field requirements of your walk-in freezer or cooler.
