When your Americana oven turns off by itself, the touchpad is the most likely cause, especially when some buttons respond intermittently or not at all. A faulty touchpad can make the oven shut off while baking or stop responding to commands. A blown thermal fuse is another possibility if the oven overheated. Test the thermal fuse for continuity with a multimeter, and replace it if it has no continuity because this fuse cannot be reset. If some buttons work but others do not, the touchpad and control panel may be defective. If no buttons respond, the control board is more likely at fault. Also check the incoming power and make sure the circuit breaker has not tripped. Less commonly, loose or burned connections, a failed relay, or another defect in the Americana oven control board or main control board can cause the oven to keep turning off. Before ordering parts, enter your model number to find the exact replacement touchpad, thermal fuse, control panel, control board, or main control board for your specific Americana range, stove, or oven.
01 - Americana Range/Stove/Oven Touchpad
If the oven turns off on its own, determine if some of the buttons on the touchpad respond intermittently or not at all. If so, it's likely the touchpad is faulty and should be replaced.

If the oven gets too hot, the thermal fuse trips to shut off power to the oven. If the thermal fuse has blown, the oven will not heat. However, this is not a common occurrence. To determine if the thermal fuse is at fault, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse has blown, it must be replaced.
03 - Americana Range/Stove/Oven Touchpad and Control Panel
If an oven won't turn on, it's possible the touchpad and control panel is defective. One way to help confirm this is to determine if some touchpad buttons respond while others don't. If some of the buttons still work, then it's quite probable the touchpad and control panel is faulty and requires replacement (if none of the buttons work, a defective control board is more likely the cause of the oven not turning on).
If an oven turns off on its own there could be an incoming power problem. Verify the circuit breaker hasn't tripped.
Common
05 - Americana Range/Stove/Oven Control Board
The board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
06 - Americana Range/Stove/Oven Main Control Board
The main control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
