224 and 225 Chair Drawer Heater System Theory of Operation

This illustration shows only the components that affect the Drawer Heater System.

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 Board(s).

When the Drawer Heater switch is turned on, current flows to the heater plate. When the heater plate is energized, it warms the contents of the drawer.
