Hey all , Its been a while but I have a Scotsman AC176 as air cooled icemaker .
It makes ice no problem but fails or goes out on HIGH CONDENSER temp during harvest .
( yes Condenser is clean ) I tried switching it to water cooled to trick it but still failed ?
Ordered new probes ....that was worse it actually didnt even run with them , supplier couldnt tell why but took my $250 for two probes . I can return the probes but Im told the fault is with the PCB , another $480 jesus ! So it adding up and yes I can recover all my money once I fix it .

Wondering if anyone has the resistances for the probes tempted to have a fiddle ? instead of buying new PCB .

Hiya,
It is a different model but resistance should be same,

Page 53 says
32,649 ohms @ 32F (0 Celsius)

Happy tinkering
