CRYSTAL ICE AUTOMATIC ICE MACHINES A603 stuck in def cyle

[sork]

Hi guys
i am working on a chinese automatic ice machine called : CRYSTAL ICE 603A,when plug in the power, the unit runs , but suction pressure drops , then unit shuts down. unplug the power ,few minutes later plug in the same prob. the water side is ok.
i think the unit stuck in def sycle or some sensor is faulty,causing the valve to close, as it is fully automatic, i initiate the automatic reset to no avail, i can not find any source to download fault code or refer to service manual.
i think the manufacturer or suppliers are in hong kong called ypt international ltd,
any help?

Could be a contol problem or lack of refrigerant, google ypt international hongkong.

Ice stuck on evaporator or stuck in door so circuit not closed for new cycle? Alignment and possible foreign matter on harvest door making P.C. stop at that point.

no ice no refrigeration takes place, unit starts , immidiatly suction pressure drops to zero, mag vale kick off , comp stops, thst is all. to restart, unplug and plug the power, the above happens.

mikeref you might be right, i took the pc to check, i was thinking it might be the sensors.

[sork]

i have tried the above no luck.

So it locks out on Low pressure. Remove and weigh gas charge. Drier might have fragmented and blocked cap tube(s). I'm not familiar with this brand of ice-maker.

i have change the dryer, recharged, check exp valve, the unit still cutting out on LP switch.

[sork]

it is a crystal ice automatic ice machine.CTM603A, metering device is tev
when i turn unit on, the waterpump starts and sprays the water to evaporator, then,waterpump stops, compressor starts, suction pressure drops, compressor shuts down.
anyone help???

the unit is mv 306 scotsman , the fault was the the mag switch and the blockage in thge filter dryer. machine was identified by the people in hong kong.

Hi Sork.
problem solved thanks for coming back to us.
So is it a Scotsman made in china, rebranded or name badge engineering.

[sork]

yes absolutely right. the blockage on the orifice of the tev caused confusion plus other minor adjustments.
