Modules
POSSIBLE CAUSES:
ƒ Loose connection to the clock module
ƒ Faulty temperature or oven mode L.C.D. module
DIAGNOSIS:
ƒ If the fault is that one segment of the display is always on or always off, replace the
L.C.D. Module. (refer to Servicing Instructions Section 7.7)
ƒ If the L.C.D. module is displaying incorrect information, check the connections from

ƒ Test for the correct supply voltage to the lower cavity power transformer.
¾ 120volts in USA or 230/240 volts in NZ / AUS / EU
ƒ Check the connection from the power transformer to the lower cavity power module.
ƒ
Check for a blown power module fuse by testing for 12
VDC
between pins 1 and 6 of
the 12-way clock connector on the power module. (refer to Technical Overview
