4. The gas burner assembly of claim 2 , further comprising a seal positioned on the temperature probe above the opening of the panel, the seal having a bottom flange positioned on the panel at the opening of the panel, the bottom flange of the seal being wider than the opening of the panel in a plane that is perpendicular to the vertical direction.

5. The gas burner assembly of claim 2 , wherein the bottom flange of the jacket is sized and positioned for directing liquid flowing on an outer surface of the jacket away from the opening of the panel.

6. The gas burner assembly of claim 1 , further comprising a mounting bracket positioned below the burner body along the vertical direction, the biasing mechanism extending between the mounting bracket and the temperature probe.

7. The gas burner assembly of claim 6 , wherein the biasing mechanism is a spring.

8. The gas burner assembly of claim 1 , wherein the jacket includes a tubular body that extends from the bottom flange of the jacket over the distal end of the temperature probe, the tubular body of the jacket having a width in a plane that is perpendicular to the vertical direction, the bottom flange of the jacket also having a width in a plane that is perpendicular to the vertical direction, the width of the bottom flange being greater than the width of the tubular body.

9. The gas burner assembly of claim 1 , wherein the temperature probe extends through a central portion of the burner body.

10. The gas burner assembly of claim 1 , wherein the jacket is removable from the temperature probe.

11. A cooktop appliance defining a vertical direction, the cooktop appliance comprising:

a panel defining an opening;

a grate positioned over the opening of the panel; and

a gas burner positioned beneath the grate, the gas burner comprising

a burner body positioned at a top surface of the top panel, the burner body defining a plurality of flame ports;

a temperature probe extending from the burner body, the temperature probe movable along the vertical direction such a distal end of the temperature probe is positioned above the grate along the vertical direction in an extended configuration;

a biasing mechanism coupled to the temperature probe such that the biasing mechanism urges the temperature probe towards the extended configuration; and

a jacket positioned over the distal end of the temperature probe, a bottom flange of the jacket positioned adjacent a bottom portion of the burner body.

12. The cooktop appliance of claim 11 , wherein the gas burner further comprises a mounting bracket, the mounting bracket positioned at a bottom surface of the panel such that the panel is positioned between the burner body and the mounting bracket along the vertical direction, the temperature probe extending from the mounting bracket through the opening along the vertical direction.

13. The cooktop appliance of claim 12 , wherein the opening of the panel has a width in a plane that is perpendicular to the vertical direction, the bottom flange of the jacket also having a width in a plane that is perpendicular to the vertical direction, the width of the bottom flange being greater than the width of the opening.

14. The cooktop appliance of claim 12 , wherein the gas burner further comprises a seal positioned on the temperature probe above the opening of the panel, the seal having a bottom flange positioned on the panel at the opening of the panel, the bottom flange of the seal being wider than the opening of the panel in a plane that is perpendicular to the vertical direction.

15. The cooktop appliance of claim 12 , wherein the bottom flange of the jacket is sized and positioned for directing liquid flowing on an outer surface of the jacket away from the opening of the panel.

16. The cooktop appliance of claim 11 , wherein the gas burner further comprises a mounting bracket, the mounting bracket positioned at a bottom surface of the panel such that the panel is positioned between the burner body and the mounting bracket along the vertical direction, the biasing mechanism extending between the mounting bracket and the temperature probe.

17. The cooktop appliance of claim 16 , wherein the biasing mechanism is a spring.

18. The cooktop appliance of claim 11 , wherein the jacket includes a tubular body that extends from the bottom flange of the jacket over the distal end of the temperature probe, the tubular body of the jacket having a width in a plane that is perpendicular to the vertical direction, the bottom flange of the jacket also having a width in a plane that is perpendicular to the vertical direction, the width of the bottom flange being greater than the width of the tubular body.

19. The cooktop appliance of claim 11 , wherein the temperature probe extends through a central portion of the burner body.

20. The cooktop appliance of claim 11 , wherein the jacket is removable from the temperature probe.
