The

should

be

carried

out

with

the

microwave

To

POWER TRANSFORMER TEST

WARNING:High voltages and large currents are present at the secondary wind-

filament winding of the power transformer. It is very dan-

gerous to work near this part when the oven is on. NEVER make any

voltage measurements of the high-voltage circuits, including the

magnetron filament.

Using
