    My ice machine has stopped producing ice. I believe that I have isolated the problem down to the 'ice full sensor'. There are a set of lasers that shoot across the top of the tray to determine when it is full. Once enough ice has been produced to break the laser it sends a signal to the control panel to stop making ice.

    I don't know enough about general electronics to understand how they work. Could I just replace the lasers (are they fairly generic?) or can I bypass them somehow. I would prefer to replace them, but don't know what type of signal they send to the control panel.

    I've attached some pictures. Thank you for any help you can provide.

    I can't resist the joke, maybe your lasers are melting your ice.
    First I'd look at the lenses on the laser/detectors, to make sure they're not just coated
    with calcium deposits from the water.
    I don't think anybody would recommend just replacing your sensor circuit, it's very possible
    something else in the circuit went bad. Without a background in electronics, you'll
    probably have to talk to somebody that services your ice maker.
    Good luck, hope it's not too expensive to fix.

    Thanks for the reply. I didn't think the sensor would be that complicated to replace.

    The machine only cost around 80 quid, so I assume getting it serviced would be almost as expensive replacing it. I can't find any documentation online for it aside from it is made in China. It is a brand called Contessa.

    I would be happy to try and just bypass the sensor, it isn't really important to the machine. I would just plug it in when I needed ice.

    Will keep searching. Appreciate the response.
