Electric Cook Control Thermostat

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.

Uses

Robertshaw oven thermostats offer a wide combination of features, making them useful for electric ranges, warming drawers & zones, hot plates, space heaters, barbecue grills and quartz heaters. They are ideal for applications requiring accurate temperature control & double pole operation.

Working Mechanism

Robertshaw oven thermostats are switches that close and open in response to the temperature they sense. They are located in the control panel, where a liquid filled temperature sensing bulb senses & maintains the oven temperature internally by cycling heat on & off. The tube does so by heating up and relaying the heat back to the thermostat. When it reaches the set temperature, the thermostat cuts off the heat source and when the temperature drops, the thermostat reactivates the oven burner & heats it again. Robertshaw gas thermostats use a double pole single throw snap action mechanism for positive off. Most units use silver contacts with heavy duty terminals for accuracy & durability.

Features

  • Robertshaw electric gas thermostats are used in conventional ovens, in combination with the ignition system, for electric heating applications.
  • They have a double pole single throw (DPST) snap action mechanism with instantaneous, positive and non fatiguing off.
  • These units react to exceedingly small movements of the diaphragms for very close temperature differential.
  • The diaphragm assembly has two stainless steel constructed diaphragms that are electrically welded together to prevent overheating.
  • These Robertshaw thermostats ensure maximum sensitivity without over-stressing the metal and are supplied with terminals mounted in four different positions for easy installation.
  • The included bulb and capillary are available in copper, stainless steel and nickel plated copper variants.
  • Robertshaw gas thermostats come with a dial to control temperature.

Compatible Accessories

  • Robertshaw 8-32 UNC Nuts: These 8-32 UNC nuts are engineered for mounting Robertshaw thermostats with 2.5 threads of screw engagement for quick installation.

Standards and Approvals

Robertshaw gas thermostats are UL listed and CSA approved to ensure efficient performance and utmost safety of the user.

Installation

  • Remove the old thermostat control, ensuring capillary routing and sensing bulb entry into lead wire terminal connections and oven equipment.
  • Take the old control and measure the length of the dial shaft. Find the groove of the new control which is closest to the measurement taken from the old control. Take two pliers, place one on each side of the selected groove and bend them both away from the stem flat.
  • Use A4590-013 pilot light kit (sold separately for only 220V applications). Remove screws according to the desired location and install the long screw provided in the pilot light kit in place of a screw just removed. Place the pilot light into position and tighten (but do not over tighten) the nut provided. Connect the two lead wires to the terminals on the control.
  • Route the capillary and sensing bulb of the new control into the oven equipment and connect the terminal wires using the screw to spade terminal adaptors, if required.
  • Mount the control using the two self tapping screws provided, which allow horizontal and palnut mounting.
  • Place a new or old dial onto the shaft. If it does not fit snugly, place a screwdriver into the shaft and twist slightly to spread the shaft.

Frequently Asked Questions

What is the lifespan of a home thermostat?

The lifespan of thermostats depends on the make, model and type of thermostat. They don't have a set lifespan for repair, maintenance or replacement, but a thermostat is generally expected to last at least 10 years.

What is a Robertshaw thermostat?

Robertshaw is a manufacturer of thermostats, valves, zone controls, timers and other electronic HVAC control components. Their thermostats are user programmable climate control devices that are responsible for operating air conditioning and heating systems.

How to use an old Robertshaw thermostat?

  • Slide the Robertshaw temperature thermostat switch to either Cold or hot position.
  • Press the programme button and hold it for 3 seconds.
  • Press the buttons to select the time (morning, day, evening & night mode) for the programme to start.
  • Use the up and down arrows to select the temperature.
  • Press the programmed 'a' button to move to the next programme.
  • Repeat the same steps for all programmes for weekdays.

What would cause a thermostat to stop working?

Incidents like frayed wires, loose connections and aged wires can cause thermostats to eventually lose connection to the heating system or AC, and prevent them from working.

How do I reset my Robertshaw thermostat?

To reset a Robertshaw thermostat, make use of a small object, such as a paperclip or a toothpick, and gently press the button situated inside a small hole on the front of the thermostat housing, labelled as 'reset'.

What does 'System On +2' mean on a thermostat?

'System On 1' feature indicates when the cooling or heating stage is energised, whereas, 'System On +2' depicts when the second stage is energised.
