Hello, Denise. Thank you for taking the time to share your review regarding your LG CBED2415B Electric Cooktop. We appreciate your feedback on the heating performance, surface cleaning, and timer functionality, as we always aim to deliver a reliable cooking experience. For temperature cycling behavior, you can refer to helpful guidance at https://www.lg.com/us/support/help-library/electric-cooktop-elements-cycles-on-and-off-ranges--20150482953750?srsltid=AfmBOoqiDHgVMFj4z8iBENPvOsvrwhuIC8Ui4dk2ymV1LxAyoAZbcBm6.
