Flakerstarts,PhotoEyesmaybedefectiveandneedtobereplaced.
2. DefectiveLevelControlRelay(LC1). 2. Placeawirejumperbetweenterminals#5(red)and#6(red)attheLevelControl
Relay(LC1).IfIceFlakerstarts,LevelControlRelay(LC1)maybedefectiveand

3. NocontrolpowerfromTransformer(T1). 3. CheckvoltageacrossTerm1(purple)andTerm2(yellow/orange)atControl
Module(CM).If24VACnotpresent,Transformer(T1)maybedefectiveandneed
tobereplaced.
4. Openswitchorloosewiring. 4. PlaceawirejumperbetweenTerm2(yellow/orange)andTerm3(red)atControl
Module(CM).IfIceFlakerstarts,tracevoltagefromTerm3.Checkallwire

5. DefectiveControlModule(CM). 5. PlaceawirejumperbetweenTerm2(yellow/orange)andTerm3(red)atControl
Module(CM).IfIceFlakerdoesnotstart,ControlModule(CM)maybedefective
