Http://www.truemfg.com/pdf/InstallManuals/GDM/gdm_english.pdf Go to this web site and check out the owners manual. On pages 13 or 14, it discusses the time clock. If the time clock is not moving to begin a defrost cycle, I would say, replace it. It does have a mechanical motor and it can fail or lock up. Hope this helps.
