hello, ive had the castle serenity for 3 months with no problems until last night. I shut stove down to clean, waited about two hours, cleaned it, started it up and it lit no problem but about 10 minutes into the heating cycle it lost power. I checked breaker panel and outlet has power, I then checked and switched fuse at power switch but still no power to stove, I unplugged it and waited until this morning to try it again and still no power. I opened it up and all connection from switch on secured. any ideas of what it could be?
