A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A cooktop appliance includes a gas burner, a user input configured to define a power setting of the gas burner, and a grate. The grate includes a sensor finger with a temperature sensor mounted thereto. The temperature sensor includes a first temperature probe extending above a top surface of the sensor finger and a second temperature probe positioned within the sensor finger. The cooktop appliance also includes a controller in communication with the temperature sensor. The temperature sensor is configured to transmit a first temperature measurement from the first temperature probe and a second temperature measurement from the second temperature probe to the controller. The controller is configured to determine a temperature of a cooking utensil positioned on the top surface of the sensor finger based on the power setting defined by the user input, the first temperature measurement, and the second temperature measurement.

Cooktop appliances are provided. A cooktop appliance can include a gas burner; a manifold having a gas input; a primary line extending between the manifold and the gas burner, wherein the primary line operates as a non-modulated minimum gas flow line when the cooktop appliance is in an automatic mode; a secondary line extending between the manifold and the gas burner, wherein a gas flow rate of the secondary line is controllable by a flow control valve; a primary valve in fluid communication with at least the primary line; and a control system including: a sensor configured to detect a temperature corresponding to the gas burner; and a controller regulating: (i) the flow control valve in response to the detected temperature to achieve a desired temperature, and (ii) the primary valve when the flow control valve is closed and the detected temperature exceeds the desired temperature.
