C" Oven Halogen Light Circuit - Thermador C302 Service Manual

Halogen Light Circuit
The halogen light transformer is a "center tap" step down transformer
with a primary and a center tap secondary winding. The primary winding
receives 120 volts AC and steps down the secondary winding to 12 volts
AC.
Terminals #6, #8 and #10 have a 12-volt AC potential. See illustration
below.
When Relay K6 (upper oven light ) or K7 (lower oven light) are activated,
the circuit is completed to neutral (terminal #8) and the oven lights come
on.
