    Abstract: The present invention provides an oil overflow alarming system incorporated in a fryer apparatus. When the fryer apparatus includes a first frypot and a second frypot, a control unit of the oil overflow alarming system detects whether at least one of a second drainage valve unit and a second supply valve unit of the second frypot is in an open position while a first drainage valve unit of the first frypot is open, where cooking oil contained in the first frypot is drained into a cooking oil filtration unit to be filtered and cleaned. When at least either the second drainage valve or the second supply valve is open, the control unit outputs an overflow signal to an alarm unit, which generates an overflow alarm corresponding to the overflow signal to urge an operator to close both the second drainage valve and the second supply valve, thus preventing cooking oil from overflowing from the cooking oil filtration unit or the second frypot.
