Page 55: Refrigeration System
Refrigeration System Inverter Compressor The new inverter compressor is not controlled by 120 VAC output from the main control board, as in previous models. The compressor is controlled by the inverter. Warning: Disconnecting the 6-pin connector does not disconnect power (120 VAC) from the inverter. The refrigerator must be unplugged before servicing the inverter or compressor. - Page 56 High compressor torque enables the compressor to start against high pressure in the sealed system. When power has been disconnected from an operating unit, the high torque may enable the compressor to start immediately upon power restoration. The compressor, if unable to start after 12 times, will wait for 8 minutes before trying again.

Page 57: Inverter
Inverter Warning: Disconnecting the 6-pin connector does not disconnect power (120 VAC) from the inverter. The refrigerator must be unplugged before servicing the inverter. Note: Certain voltmeters will not be able to read voltage output from the inverter. If no voltage or erratic voltage is measured, it does not necessarily indicate a faulty inverter. - Page 58 Note: When servicing the inverter, it is important to dress the wiring to keep low- voltage DC wiring and 120 VAC wiring separate. To remove the inverter: 1. Unplug the unit. Screw 2. Open access cover. 3. Remove the screw securing the inverter to the sheet metal dividing wall.

Page 59: Accumulator
Accumulator An accumulator has been installed at the inlet of the compressor to prevent liquid refrigerant (low quality) from entering the suction line. Changes in compressor speed (transition state) can temporarily reduce refrigerant quality. The accumulator compensates for this by collecting and holding up to 2 oz of liquid while allowing Accumulator vapor to pass. -
