Hi all,
I'm looking for a bit of help with an ice machine. I have an Ice Craft ZB-15P which I took from our office when it was closed, its been used regularly but last week I was getting it ready for summer (quick clean and run a couple of ice cycles to discard) and when I switched it on, the fan started for 2 secs, stopped 2 secs, started 2 secs, then stopped and didn't come back on.
I cant remember how much the fan came on last year so proceeded to make some ice, the ice wasn't very big and the machine soon started to overheat so I switched it off.
I've done a bit of diagnostics and worked out its the pressure switch that runs the fan that has failed, if I bypass the pressure switch the fan is on constantly and the machine works well when producing ice. There is a small problem in that some of the ice doesn't drop off the freezing/ice maker prongs, but I'm wondering if this is because the fan is running constantly and the element warming cycle to eject the ice from the prongs is not getting warm enough.
The pressure sensor is marked up as Chang Heng YK-01L and the contacts are currently constantly open so the fan doesn't get powered on.
I'm wondering how I go about getting the pressure sensor replaced, I can rotate the black plastic housing and pins by apply a lot of force, but it does not seem to be a screw fitting, is it likely to be soldered on to the copper pipe?
I've searched online for the part and I cant see where to get a replacement, is there an alternative part do you think?
Schematic:
11446
Close up of pressure sensor:
11447
View of components and wiring (cables re-routed for easier viewing):
11448
Thanks in advance for any help.
