DIAGNOSTICS & TROUBLESHOOTING

Diagnostics are used to determine whether the

optics circuits are operating properly. If the

optics circuits are malfunctioning, the ice maker

will not operate.

The optics system consists of an emitter board

and a receiver board. The emitter board trans-

mits a beam of infrared light that is detected

by the receiver. If the beam of light is inter-

rupted, the ice maker will not operate.
