Robertshaw manufactures electric cook thermostats for electric heating, automotive, transportation, storage and water supply applications. These gas thermostats are replacement units for Ranco G1 and 5300 Series thermostat replacement units. Robertshaw gas thermostats offer high sensitivity without over-stressing the metal and are suitable for harsh applications which require precise temperature control. They feature two stainless steel diaphragms to resist corrosion and handle temperatures up to 200 degrees Fahrenheit. These control thermostats make use of a double pole single throw (DPST) snap action mechanism for a positive switch off. These Robertshaw oven thermostats are supplied with terminals mounted in four different positions to ensure tight installation. The attached rotary switch or infinite switch regulates the power generated by an electric heating element. Choose from a wide range of Robertshaw oven thermostats, having stem lengths up to 2 inches.
