RESET	The control board stores fault codes in volatile memory. When power drops unexpectedly, the microprocessor can latch into a stuck error state even if the hardware itself is totally fine. A full power cycle forces the board to reinitialize and run its startup diagnostics from scratch, which clears any phantom fault flags that got written during a bad power event. low	low
