626 Chair Drawer Heater Theory of Operation

This illustration shows only the components that affect the drawer heater. A detailed description of current flow during this function also appears below.

Drawer Heater

Line voltage (115 VAC) is supplied directly to the Drawer Heater thru two inlet fuses, isolation transformer, and Drawer Heater switch. Voltage bypasses the PC Boards.
