SELF DIAGNOSIS CONTROL METHOD FOR MICROWAVE OVEN

摘要

PURPOSE: A self diagnosis control method for a microwave oven is provided to detect the more accurate zero point of the weight as well as to perform an automatic self diagnosis. CONSTITUTION: A self diagnosis control method for a microwave oven comprises the steps of:external force generation judging(S1,S2) to judge the existence of the external force possible to affect the output value of a weight sensor when the power supply is fed according to the drive of a microwave oven; average weight value detecting(S5,S6,S7) to detect many weight values according to the period from the weight sensor and operate the values by the average value; standard error judging(S8) to judge if the operated value is detected within the allowable error; and manual converting(S13) to modulate the zero point of the weight sensor by a user.
