An oven that keeps heating after you've turned it off is one to take seriously — it's almost always a stuck relay on the control board, and it means the element is getting power it shouldn't. The fix is a common repair, but the first job is making it safe. Here's exactly what to do.
The control board uses relays to switch the heating elements on and off. When a relay's contacts weld shut, the element stays powered even though the display says "off" — so the oven keeps heating.
Check it: This is the classic cause and it's a control-board (EOC) repair. Kill the breaker to make it safe, then a tech confirms and replaces the control board or relay.
A momentary control glitch can rarely leave it in a heating state; a full power-down clears a glitch.
Check it: Turn the oven off at the breaker for 5 minutes, then back on. If it powers up normal and shuts off correctly on command, it may have been a glitch — but watch it closely. If it keeps heating, it's the relay.
A shorted oven sensor can make the control think the oven is too cool and keep calling for heat, so it never reaches setpoint and seems like it won't stop.
Check it: If the oven runs hotter and hotter or never satisfies, a tech checks the oven sensor alongside the control.
On an older oven with a mechanical selector or thermostat, a stuck switch or shorted thermostat can hold the element on.
Check it: A tech tests the switch/thermostat on older, non-digital ovens.
Usually repair — a control board (EOC) is the common fix and it's well below a new range on most models. Because a stuck relay is a real safety issue, kill the breaker and get it diagnosed rather than living with it.

Make it safe first — turn off the oven's breaker so the stuck element stops heating. Then leave it off and get it diagnosed. The cause is almost always a welded (stuck) relay on the control board, which a tech replaces. Don't keep using an oven that won't shut off on its own.
The control board switches the elements with relays; when a relay's contacts weld shut, the element keeps getting power even though the oven says off. That's the #1 cause and it's a control-board repair. Kill the breaker to make it safe until it's fixed.
Yes — a stuck element getting continuous power is a burn and fire risk if left running. Shut the oven's breaker off to cut power to it, and don't use it until a tech replaces the stuck relay/control board. Your $50 Quick Check credits toward the repair.
