Spinflo hob - control sticking

We had been using both hob burners and the grill burner to cook a meal so the whole structure was quite hot. The right hand hob control (next to the grill) was stuck on the lowest setting and would not turn off. We left it for about 30 minutes and then it turned off with no problem. Just a bit worried that this mighvv TV happen again. Had anyone else experienced this? Thanks

Yes ours get sticky when hot, do you have a heat shield that pulls out to protect the knobs from heat coming from the grill/oven. The knobs are filled with a special grease.

Thanks we have no heat shield but I’m sure the problem arose because the knobs got hot. I will see if I can contact Spinflo for advice, I think they may have been taken over.
