The Supco GC505 Cold Control Kit is an essential component for technicians servicing commercial refrigeration and frost-free residential units. As a direct 3030-505 replacement, this universal refrigeration thermostat is engineered to provide precise temperature regulation across a broad operating range. Featuring a 24-inch capillary tube, the GC505 allows for versatile sensor placement, ensuring accurate monitoring at critical evaporator points. This cold control kit is designed with a constant differential of 13°F, maintaining consistent cycling to prevent compressor short-cycling and reduce operational wear. With a temperature range of 16°F to 49°F, this refrigeration temperature controller provides the flexibility needed for diverse cabinet environments. The included universal mounting hardware simplifies field installation, allowing contractors to consolidate inventory and address multiple service calls with a single, high-reliability part. Key Benefits for Technicians Broad Range Compatibility: Calibrated for 16°F (Cold Off) to 49°F (Warm On), making it ideal for various cooling applications. Durable Construction: Built to withstand demanding HVACR environments with high-quality internal switching components. Universal Versatility: Direct replacement for the 3030-505 and suitable for brands like GE, Carrier, and Frigidaire. Precision Cycling: Specifically engineered for frost-free and conventional units requiring constant differential control. Flexible Installation: Features a generous 24-inch capillary for easy routing through insulation and cabinet walls. Common Questions & Troubleshooting Is the Supco GC505 compatible with freezer applications? The GC505 is primarily designed for refrigeration systems with a low-end cutout of 16°F. For deep-freeze applications requiring temperatures below 10°F, verify the specific thermal requirements of the evaporator coil before installation. Can this unit replace other OEM cold controls? Yes, the GC505 is a universal kit designed to replace a wide array of part numbers beyond the 3030-505, including various GE WR9X and Carrier HK series thermostats. Always confirm the temperature range and capillary length match the original part. How does the constant differential feature benefit the system? The GC500 series maintains a fixed temperature difference between the "on" and "off" points throughout the adjustment range. This ensures predictable cooling cycles and prevents the evaporator from icing up in humid conditions.
