Repair or Replace Rotisserie Safety Valve or Thermocouple.

Use Safety Valve to Test Thermocouple.

Below are several safety valves from several different barbecue grills. Although all gas log fireplace pilot systems use the same technology we are focussing on the gas grill valve here. In the upper right corner is the DCS safety valve.

Notice all the safety valves have a aluminum cover where the thermocouple screws to the valve.

To test the safety valve and the thermocouple first remove the safety valve from the barbecue. On the DCS the safety valve -- all the DCS valves -- screw into the manifold. To remove the valve disconnect the gas line that extends all the way back to the rotisserie burner and disconnect the thermocouple. Unscrew the entire valve to remove. Remove the aluminum cap where the thermocouple attaches.

Inside the valve we will see the solenoid once the cap is removed. This solenoid slides right out of the valve. Below the safety valve there is a small metal slide that will not usually come out and it is difficult to slide back in to the tiny hole where it installs inside that valve below the solenoid.

Notice the spring at the far end of the thermocouple. When you depress the DCS button or with other BBQ brands push in the control valve knob this spring is compressed and the metal end is pushed up against the solenoid.

Look for damage. Images at the bottom of this page show a damaged solenoid. The item is made with plastic. The copper coils and metal that becomes the electro-magnet is inside this metal housing. If the inside of the saefty valve is damaged obviously that is what needs to be replaced. It should be cleaned and degreased so movement and connections are easy.

Attach the thermocouple to the cap and then insert the solenoid in the car so the side without the spring is touching the thermocouple just as though it was inside the valve.

In this example I needed extra arms so I wrapped the solenoid to the cap with a few rubber bands. This held the thermocouple and cap to the solenoid so I did not have to hold it pushed up against the inside of the cap. Push the spring so the tip is pushed up against the plastic housing. Apply heat to the back tip of the thermocouple.

If the theromocouple is functioning properly the heat at the tip of the thermocouple created a millivolt of electrical charge. The electrcity travelled through the copper line and into the solenoid where it charged a piece of metal and created an electro-magnet.

Now as long as the heat conduction at the tip is hot the millivolt charge will continue. Remove your finger from the spring. Instead of springing back out the spring will stay compressed against the plastic housing.

When the tip of the thermocouple is removed from the candle -- or whatever flame you are using to test the thermocouple -- the spring will push the metal back out and away from the plastic housing within a few seconds.

Replacement safety valve for DCS gas bbq grill rotisserie. Gas line goes into safety valve and out of safety valve to rotisserie burner. Thermocouple attaches to allow or to stop gas flow using millivolts generated by heat as a safety feature that stops gas leaks.

Partially refunded when selected with button and bezel below.

Safety button fits on button for DCS rotisserie safety valve. This is the button that fits in to the 11050 bezel for the rotisserie valve and attached a top the valve button.

When safety valve, button cover and bezel are selected together, a partial refund will be applied at shipping because DCS has had disproportionate price increases.

Plastic replacement bezel mounts to control panel and holds the safety button for DCS rotisserie safety valve.

When safety valve, button cover and bezel are selected together, a partial refund will be applied at shipping because DCS has had disproportionate price increases.
