Sounds like a relay stuck on. A relay is basically a mains switch operated by a low voltage microprocessor board. Sometimes the switch contacts weld shut which means it cant turn off. Sometimes the relay is on a discrete board, sometimes its incorporated onto the processor board. POWER OFF before any inspection.
