Help diagnosing the ice maker

Hello Danielle – Since your unit has optics (flashing light on the freezer door liner) I will start with the simple diagnostics per the manufacturer – start by installing all components that may have been removed.
Step 1 – Open the freezer door and look at the optics light.
What do you see? 2 options, option A and option B
A. Two pulses followed by a one second delay which is repeated over and over.
If you see this:
1. The flapper door on the emitter is blocking the beam – Go to Step 2
2. The optics are faulty – Go to Step 2
B. No lighted pulses
If you see this:
1. The icemaker is in a harvest mode (mid-cycle) – Hold the freezer door switch closed to allow the icemaker to complete the cycle (roughly 3 minutes) – when in the harvest mode, the lighted pulse will flash once every second.

Step 2 – Press in the emitter flapper door (opposite side of flashing light) to unblock the optics beam (make sure your hand is not blocking the beam as well).
What do you see? 2 options, option A and option B
A. Two pulses followed by a one second delay which is repeated over and over
If you see this:
1. The optics are faulty – Replaced the emitter and receiver boards (sold as a pair).
B. LED is steadily on
If you see this:
1. The optics are working properly – the problem exists in a different component.

This should at least get us started, please report back with findings if more assistance is needed and I can help from there.

Thank You
