10 Tests
eikon e2s Service and Repair Manual UL 113
10.4 High voltage components (casing removed)
High Voltage Transformer test
Ensure the following requirements have been met before starting the test:
 The appliance has been disconnected from the power supply and protective measures have been
taken to ensure the power cannot be switched on again.
 The appliance is cool.
 The high voltage capacitors are discharged before commencing work.
 Anti-static precautions have been taken.
 The casing of the appliance has been removed.
High voltages and large currents are present at the high voltage capacitor.
It is very dangerous to work near this part when the oven is on.
NEVER make any voltage measurements at the high voltage circuits, including the magnetron filament.
1.
Remove all connections from the transformer.
2.
Using a Digital Multi-Meter (DMM), check the resistance of the
windings.
Results should be as follows:
3.
Mains winding between tags, approx. 1.1 Ω.
4.
High Voltage winding, approx. 60 Ω.
5.
Filament winding between terminals, less than 1 Ω.
6.
Using a megger, test the insulation resistance between:
● Primary winding and chassis. Pass if reading is over 10 MΩ
● Filament winding and chassis. Pass if reading is over 10 MΩ
NOTE: One end of the High Voltage winding is connected to the
chassis, so this is not tested.
