Danfoss 077b7007 Service Thermostat with Accessories B3 Freezer Cold Control

Product Description

The Danfoss 077b7007 is a B3 service thermostat designed for freezers with passive alarm systems. It ships as a complete service kit with all accessories included, making it a ready-to-install replacement for technicians working in the field. Mechanical cold controls like this one regulate the refrigeration cycle by sensing temperature through a capillary tube and opening or closing a circuit based on preset cut-in and cut-out thresholds. This unit covers a wide operating range, with a warm cut-in temperature of 14 degrees Fahrenheit, a warm cut-out of 1.4 degrees Fahrenheit, a cold cut-in of -11.2 degrees Fahrenheit, and a cold cut-out of -30.1 degrees Fahrenheit. That range makes it well suited for commercial and residential freezer applications where consistent low-temperature control is critical. The capillary tube length is 2300 millimeters, providing enough reach to position the sensing bulb correctly within the freezer cabinet. Danfoss is a globally recognized manufacturer of refrigeration and HVAC controls, and the 077b7007 follows their engineering standards for reliable, repeatable temperature switching. HVAC-R technicians, refrigeration service pros, and appliance repair specialists will find this thermostat straightforward to source and install as a direct service replacement. Having the accessories bundled in the kit reduces time spent sourcing additional hardware during a service call. This mechanical cold control does not require electronics or a power supply to operate, which simplifies diagnosis and replacement in the field.
