    Default SubZero 550 - Ice Maker not working (tried many other tips from the forum)

    RepairClinic
    Model Number: 550
    Brand: Sub Zero
    Age: More than 10 years

    I have a SubZero 550 that stopped making ice. These are the notes/results based on trying things I've read from other messages in these forums:
    - Ice feeler arm is locked in the up position
    - I've tried to force it down but it won't budge (and I don't want to break it)
    - Defrosted the freezer
    - When I restarted the fridge/freezer the water filled the ice maker
    - The feeler arm is still locked in the up position
    - There are 3 switches in the freezer. 1 for the light, 1 that turns on the freezer fan and 1 the ice maker tray closes
    - I taped the ice maker tray switch closed to force cycle (is this the only one that needs to be "closed?)
    - When it is taped shut the ice maker makes a "ticking" noise - I've checked a day later and it is still making the ticking sound but no ice has dropped and feeler arm is still up.
    - Tried to force cycle the ice maker (jumpering T and H for 10 seconds). There was a small spark so the jump was working but it made no effect

    I feel that the issue is around the feeler arm being locked in the up position but I don't want to force it down.

    Other thing I haven't tried yet is to reset the circuit breaker.

    Anything else I can try or do I need a new ice maker?

    Thanks

    Derek

    The Sub Zero ice maker 4202850 is no longer available. 4202850 changes to: Ice Maker 7002748

    I believe this one will work:

    You will need to use the old wire harness and shut off arm
