Heatcraft Refrigeration 4752C Thermostat

The Heatcraft Refrigeration 4752C Thermostat is a high-precision fan delay switch designed for critical temperature regulation in commercial cooling systems. This OEM replacement part is engineered to manage evaporator cycles effectively, featuring a fixed setpoint that opens at 75?F and closes at 40?F. Built for industrial durability, it serves as a reliable heater limit thermostat for large unit coolers, ensuring that fans engage only when the coil has reached the optimal operating temperature. This prevents the circulation of warm air during the initial cooling phase, maintaining strict climate control for perishable inventory. The 4752C is a direct Bohn replacement thermostat and is fully compatible with unit cooler brands under the Heatcraft umbrella, including Larkin, Chandler, and Climate Control. It specifically fits BHE1020, BHE1200, and BHE1390 electric defrost models. For technicians performing commercial refrigeration repair, this two-wire limit switch provides a drop-in solution to restore efficient defrost termination and fan delay functionality.

• Precise Thermal Control: Fixed 75?F open and 40?F close calibration ensures accurate fan delay and defrost termination.
• Broad Compatibility: Serviceable across major Heatcraft brands including Bohn, Larkin, and Chandler.
• Optimized Efficiency: Preventative heater limit functionality stops fans from blowing warm air during defrost cycles.
• OEM RELIABILITY: Genuine factory-spec construction matches original equipment standards for long-term system performance.

What happens if my fan delay thermostat fails?
A faulty Heatcraft 4752C can cause fans to run during defrost, leading to steam dispersal and ice buildup on the ceiling or product, or prevent fans from starting after a defrost cycle completes.

Is the 4752C compatible with 240V systems?
Yes, this refrigeration thermostat is typically rated for 120/240V AC applications, making it suitable for a wide range of commercial unit cooler configurations.

Can I use this to replace a 5708L part number?
The 4752C is a recognized cross-reference for several older models, including the 5708L and SL5708, provided the 75/40 temperature range matches your system requirements.
