How do I hard reset my oven?

How to hard reset oven generally applies to all brands including Samsung, LG, Whirlpool, GE, and involves power cycling to reboot electronic control board and clear error codes, useful when oven display frozen, not heating, or showing error. Steps include turn off oven using Off or Cancel button, then unplug oven from wall outlet if accessible, for built in wall oven and ranges you cannot unplug easily, turn off circuit breaker that supplies oven in electrical panel, leave power off for 5 to 10 minutes to allow capacitors on control board to fully discharge and memory to clear, press and hold power or cancel button while unplugged for 5 seconds to drain residual power, then plug back in or turn breaker back on, turn on oven and reset clock and settings, and test by setting bake to 350F to see if heats. Hard reset clears temporary glitches but does not fix hardware failures like bad heating element or sensor, so if error persists after reset note error code and call technician.
