85800190078890 Genuine Cooktop Control Knob Black for Westinghouse Cooktops GHH90S GHH90K GHH92S GHH92K GHH95S GHH95K GHH11S GHH16S

A missing or split knob makes a cooktop awkward and unsafe to use. This genuine Westinghouse black control knob, part 85800190078890, is listed for the GHH11S and GHH16S cooktops, the GHH90K and GHH90S, the GHH92 in K or S versions, and the GHH95K and GHH95S. Electrolux group parts lists also show it as 0019007889, so either number will lead you to the same knob.

Westinghouse cooktop knob cracked or spinning?

Each control knob pushes onto a shaft on the burner tap or control switch and turns it as you adjust the heat. Inside the knob is a shaped socket that grips the flat on the shaft. Over time that socket can split or wear round, so the knob spins without turning anything, slips off when you pull it, or needs to be pushed hard to engage. Heat and cleaning products can also crack or fade the knob face. Swapping a worn knob restores a firm grip and clear control of each burner.

Part details

• Genuine Westinghouse part 85800190078890
• Electrolux group number 0019007889
• Black finish

Fitting the new knob

Make sure every burner is off and the cooktop is cool. Pull the old knob straight up off its shaft without twisting, then line up the socket in the new knob with the flat on the shaft and press it down firmly. Check it points to the off position. If the shaft itself is loose or damaged, the tap or switch underneath needs attention instead.

Questions about this part

How many knobs should I order?

Order one for each knob you are replacing. Many owners swap the full set so the colour and finish match across the cooktop, as older knobs fade over time. Check your cooktop model starts with GHH and matches one of the listed models before ordering.
