The Samsung stove burner won’t turn off, and the problem was the infinite switch.
When our technician arrived at the client’s home, the stove had already caused some stress. The Samsung stove burner had been staying on by itself. The client had managed to coax it off by fiddling with the dial enough times, but that was only half the problem. Even after the burner finally shut off, the indicator light stayed on. The stove was telling them the burner was still active. It wasn’t safe to ignore, and it wasn’t something that was going to fix itself.
A burner that won’t respond to its knob is the kind of problem that makes you nervous in your own kitchen. The client did the right thing by calling it in.
The diagnostic pointed to a faulty infinite switch.
After running a diagnostic, the cause was clear: the infinite switch had failed. The infinite switch is the component behind the knob that controls both the burner heat and the indicator light signal. When it starts to fail, the internal contacts can stick. That’s what happened here. The contacts weren’t releasing properly, so the burner stayed on. Once the client worked the dial enough to force the contacts open, the burner shut off. But the switch was too far gone to send the correct off-signal to the indicator light, so the light stayed on.
Our technician replaced the infinite switch. Once the new part was in, the stove responded exactly the way it should. Burner on, light on. Burner off, light off. No more guessing, no more fiddling with the dial. One more happy customer.
Burner won’t turn off? Don’t wait. Start with a diagnostic.
A burner that won’t shut off is not a problem to live with. If your stove top is behaving the same way, a failing infinite switch is a real possibility. Before you order any parts, get a proper diagnostic done first. It’s the fastest way to know exactly what you’re dealing with, and it saves you from spending money on the wrong fix.
