Sunray Oven won't turn off
If your Sunray oven won't turn off or keeps heating after you press the cancel button, shut off the power at the breaker or unplug the range and let it cool before testing parts. The most likely cause is a failed Sunray range/stove/oven touchpad or control panel. A shorted touchpad can send incorrect commands through the touchpad ribbon, so disconnecting the ribbon from the oven control board can help confirm the problem. If the touchpad is not the cause, the temperature control thermostat may be faulty, although this is less common. Next, check the oven control board. A relay that has shorted closed can send continuous voltage to the bake or broil circuit, causing the oven to keep heating. A shorted bake element or broil element can also prevent the oven from turning off. Look for holes or blisters, then use a multimeter to test the element and check for a short to its outer case. Replace the defective part, and enter your Sunray oven's model number to find the exact replacement touchpad, control board, thermostat, bake element, or broil element for your range.
01 - Sunray Range/Stove/Oven Touchpad and Control Panel
If the oven won't turn off, it's possible that the touchpad has shorted or is malfunctioning in some other way. To help determine this, shut off the power to the appliance to allow it to cool down and disconnect the touchpad ribbon from the control board. Restore power to the unit and observe whether or not the oven turns on with the touchpad ribbon disconnected. If the oven does not turn on, it's likely the touchpad is the source of the problem and the component will need to be replaced.

02 - Sunray Range/Stove/Oven Touchpad
If the oven won't turn off, you should unplug the power cord or shut off the power supply and let the oven cool down. Disconnect the touchpad ribbon from the control board and restore power to the oven. If the oven does not start to heat back up with the touchpad ribbon disconnected, the touchpad is likely defective and will need to be replaced.

03 - Sunray Range/Stove/Oven Temperature Control Thermostat
The temperature control thermostat monitors the temperature inside the oven and cycles on the heat when the oven temperature gets too low. If the temperature control thermostat fails, the oven won’t heat. However, this is not very common. Before replacing the oven thermostat, first check more commonly defective components—specifically the igniter and the bake and broil elements. If these components are not defective, the temperature control thermostat might be at fault. The temperature control thermostat cannot easily be tested. If you suspect the thermostat is defective, replace it.

04 - Sunray Range/Stove/Oven Oven Control Board
The oven control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If one of the control board relays shorts closed, the control board may send continuous voltage to the heating circuit. If the oven continues to heat after it is turned off, the control board is likely defective. If the control board is defective, replace it.

05 - Sunray Range/Stove/Oven Bake Element
Sometimes, if the heating element burns out, it can short out to the inside of the oven. If the heating element has shorted out, the oven will not turn off. Often, if the bake element has shorted out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has shorted out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.

06 - Sunray Range/Stove/Oven Broil Element
If the broil element is shorted out, the oven may not turn off. Often, if the element has shorted out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element is shorted out, use a multimeter to test the element for continuity. If the broil element shows continuity from the terminals to the outer case, this indicates that it is shorted out. If the broil element is shorted out, replace it.
