Robertshaw 4290-006 Gas Thermostat

The Robertshaw 4290-006 is a professional-grade snap-acting hydraulic thermostat engineered for precise temperature regulation in demanding commercial kitchen environments. Designed for high-duty applications such as commercial fryers, griddles, and convection ovens, this GS series gas control operates by interrupting gas flow to the burner once the setpoint is reached. Technical specifications include a 200°F to 410°F temperature range, making it ideal for standard frying and baking cycles. Its 30-inch capillary and 1/4" x 5-3/8" nickel-plated bulb ensure accurate thermal response times and flexible routing within tight cabinet spaces. HVACR technicians will appreciate the 1/4” tubing inlet and outlet connections, providing a robust fit for 30,000 BTU systems. This unit is compatible with 700-800 series diaphragm gas valves to scale capacity up to 600,000 BTUs for heavy-set equipment. Built to withstand an ambient temperature of 300°F, this Robertshaw gas thermostat is the industry standard for maintaining consistent uptime in high-volume cooking lines.
