A motor drive control device for driving a single phase motor having a coil of a first system and a coil of a second system includes a first drive circuit configured to control energization to the coil of the first system, a second drive circuit configured to control energization to the coil of the second system, and an adjustment circuit to which a first monitor voltage output from the first drive circuit and a second monitor voltage output from the second drive circuit are input. One or both of the first and second drive circuits has at least one of an input terminal and an output terminal. The adjustment circuit performs an adjustment operation of applying a predetermined voltage to at least one of the input terminal and the output terminal based on the first and second monitor voltages.
