Frigidaire CGMV173KB Servicing page 5

WARNING
Certain initial parts are intentionally not grounded and present a risk of electrical shock only during
servicing. Service personnel - do not contact the following parts while the appliance is energized:
Inverter unit, that includes high voltage capacitor, high voltage power transformer, high voltage
rectifier, heat sink, etc., magnetron, high voltage harness etc.;
If provided, fan assembly, cooling fan motor.
All the parts marked "*" on parts list are used at voltages more than 250v.
Removal of the outer wrapper gives access to voltage above 250v.
All the parts marked "ä" on parts list may cause undue microwave exposure, by themselves, or when
they are damaged, loosened or removed.
WARNING
This service manual is intended for use by persons having electrical and mechanical training and a
level of knowledge of these subjects generally considered acceptable in the appliance repair trade.
Electrolux home products cannot be responsible, nor assume any liability, for injury or damage of
any kind arising from the use of this manual.
WARNING
Never operate the oven until the following points are ensured.
(A) The door is tightly closed.
(B) The door brackets and hinges are not defective.
(C) The door packing is not damaged.
(D) The door is not deformed or warped.
(E) There is no other visible damage with the oven.
Servicing and repair work must be carried out only by trained service personnel.
Danger High Voltage
Do not energize a microwave oven with the outer case cabinet removed, because a microwave oven generates high
voltage in the circuit.
If you intend to operate the oven employing the high frequency switching power converter circuit, you should take
special precautions to avoid an electrical shock hazard.
The high voltage transformer, high voltage capacitor and high voltage diode have energized high voltage potential
of approximately 8KV.
The aluminium heat sink is connected to the switching power transistor collector pole, and has an energized high
voltage potential of approximately 650V peak.
DO NOT ACCESS THE HIGH VOLTAGE TRANSFORMER, HIGH VOLTAGE CAPACITOR, HIGH VOLTAGE
DIODE AND HEAT SINK WHEN THE POWER SUPPLY IS CONNECTED TO AN ELECTRICAL OUTLET.
