Hotpoint RGA724EKWH 5.0 cu ft 30 in Gas Range with Sealed Burners and Continuous Grates MECH-KNOB Error Fix: Control Knob Stiff, Won't Turn, or Feels Loose

A surface burner or oven temperature control knob is very stiff to turn, will not turn at all, or feels loose and spins without engaging — grease, food spills, and cleaning product residue can seize the valve stem underneath the knob over time; DO NOT force a stuck knob as the valve shaft inside can snap off, requiring a much more expensive valve replacement; remove the knob by pulling it straight off and try applying a small amount of penetrating oil to the exposed valve stem; if the stem is badly seized, the gas valve assembly or infinite switch (electric) may need professional replacement; a knob that spins freely without clicking or engaging has a worn D-shaft — the knob may need replacement or the valve stem itself may be rounded off
