how to stop frigidaire self-cleaning oven

I recently purchased a Frigidaire self-cleaning oven and I’m having difficulty figuring out how to stop the self-cleaning cycle. I’ve read the manual and followed the instructions, but the oven is still in the self-cleaning mode. I’ve tried pressing the “Cancel/Off” button, but nothing happens. I’m not sure what else to do and I’m hoping someone here can help me out. Does anyone know how to stop the self-cleaning cycle on a Frigidaire self-cleaning oven? Any advice would be greatly appreciated. Thank you!
