Robertshaw 4290 Gas Thermostat

The Robertshaw 4290 gas thermostat regulates natural-gas equipment between 200 and 400 degrees Fahrenheit. A 30-inch capillary tube connects the sensing bulb to the control body. The 3/8-inch pipe connection fits many commercial cooking appliances. A heat-resistant plastic dial is included for temperature adjustment.

Installation and common issues

Mount the control body securely and route the capillary tube without sharp bends or kinks that could restrict fluid movement. Ensure the 3/8-inch pipe threads seal cleanly to prevent gas leaks. Position the sensing bulb so it contacts the heated surface evenly; poor contact causes inaccurate temperature control.

Commercial kitchen fit and limits

This thermostat suits repair or replacement on Cecilware, Commodore, Comstock Castle, Hobart, Jade Range, South Bend, Star, and Wolf equipment that specifies a 30-inch capillary and 3/8-inch bulb. Operations needing a different temperature range, capillary length, or connection size should select another control.
