If your Sunray electric stove burner won't turn off, turn the burner control to Off and disconnect power at the circuit breaker until you identify the problem. Start by inspecting the control knob, since a cracked or damaged knob may not turn the surface element switch stem far enough to stop the burner. If the knob is intact and the electric stove burner keeps heating, the surface element switch is the most likely failed part. Its internal contacts can fuse together and continue sending voltage to the surface element even when the control is set to Off. On Sunray electric stoves with touchpad controls, a faulty oven control board, control panel, or surface element board can also send continuous voltage to the burner. Check for burned components, damaged wiring, or a shorted surface element before replacing a board. This troubleshooting applies when an electric stove burner is not turning off, including a glass top stove burner or coil burner. Enter your Sunray model number to find the exact replacement knob, surface element switch, control panel, oven control board, or surface element board for your specific electric stove.
01 - Sunray Range/Stove/Oven Knob
If a range's surface element won't turn off, you should first inspect the control knob for damage. A broken knob may be unable to rotate the surface element switch stem to stop voltage being sent to the element.

02 - Sunray Range/Stove/Oven Surface Element Switch
The surface element switch sends voltage to the surface element coil. Sometimes, when the surface element switch fails, the electrical contacts inside the switch fuse together, causing the switch to send continuous voltage to the surface element. If the surface element switch is defective, replace it.
If the control knob is cracked or broken it may not be turning the stem on the switch. Inspect the control knob and confirm the switch is in the off position. If the control knob is damaged, it will need to be replaced.

04 - Sunray Range/Stove/Oven Oven Control Board
On some range models, the control board provides voltage to all of the appliance's electrical components. If the board is defective, it might send continuous voltage to a surface element even after the element has been turned off. If you've confirmed the surface element itself has not shorted and the element is controlled by a touchpad, it's likely the control board is faulty. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance's wiring diagram.
A range's control panel can allow the user to select the heating functions for both a stovetop and an oven. If the control panel is defective, one or more of the buttons may have shorted and you will not be able to turn off the element. If you've confirmed the surface element itself has not shorted and the element is controlled by a touchpad, it's likely that touchpad or control panel is faulty.
06 - Sunray Range/Stove/Oven Surface Element Board
If a range's surface element is controlled by a touchpad, it's possible the surface element board has a shorted component that is sending continuous voltage to the element. You can inspect the board for signs of burning or a shorted component. If the surface element and wiring are not shorted it is likely the surface element board is damaged and will need to be replaced.
