    Hi Mate,

    When theTech change the Expanson Valve last time , he didn't change the filter dryer he only change the TXV , now he is changing both now. I hope there no more to be fixed, its very expensive exercise, the new valve TX is $790.00 and the filter is $150.00 but i have no choice.



    2.

    Do you know where i can get a expanson valve for one of my other machine, I have a manitowoc model DG12020 has two evaporator, one of the expansion valve is leaking, which cause the one evaporator with no ice and the other with ice up to the ice probe. When i check the expansion valve one has ice and the other valve no ice on it.I would much appreacted if you know where i can get those expansion valve. im happy to buy two but i don't know where to look for .



    Many Thanks

    Was the system filter dryer on the refrigerant side changed at the same time as the TXV was changed. Moisture in a system will freeze in the expansion valve stopping circulation of refrigerant. Under normal conditions expansion valves do not fail in 4 months.

    When installing a new Expansion valve it is necessary to protect the valve body from excess heat by wrapping the body with a wet cloth during the soldering process. Proper instructions are included with each valve when shipped.

Personally I think the prices that you paid for the new TXV and dryer are VERY far out of line.Get what information you can off of the TXV power assembly and valve body along with the manufacturer of the valve and I will see what I can find out for you. If it is the power assembly that is rusted out and leaking there are kits for replacement parts on most valves.

Scottsman SCE170A-1B how can i have to make ice faster


The only way to make ice faster for this machine is done with cooler ambient room temperature and colder water temperature from supply water before it reaches water sump tray.

I have a MV450 icemachine that work for up to 4 days without any problem .Then it cuts out the hi pressure indicator light up .i have checked the gas charge and cleaned the condensor


The magnetic switch just lets the machine know it finished a harvest and start ice production all over again. high pressure could be a dirty coil, fan motor stops working, a possible refrigerant restriction, or the room that the machine is in is getting to hot but this would cause the production of ice to take longer. it should be making ice every 15 to 18 mints in a 74 deg room.

1. bin full when bin is empty means that the bin control sensor is dirty or need to be replaced. But since your having problems with water over flowing also i would bet that your machine needs a good cleaning. is you water full light on or off? if off and water sump try is full then you need to pull water sensor out and clean or replace it. if water sensor light is on then you need to replace water inlet valve.

I have some problem with our machine scotsman mv450 is to long product ice very slowly


Min freeze time 6 minutes and max freeze time 45 minutes. the 6 minutes is with perfect conditions. Example: Cycle time water temp was 50 degrees coming in to the water sump tray from water supply and the Ambient air temp surrounding the machine was a constant 70 deg than the machine should make ice every 10 - 12 minutes.now we know that the water temp from the water source is not going to be 50 deg and room temp will not be 70 deg all the time so the warmer water temp and ambient air temp is the longer it takes to make ice. one thing you wont to check is the water inlet valve to make sure it is not letting water seep through causing water temp not to cool down from running across evap plates. make sure the condenser coil is clean this will slow down production of ice.

Mv450 scotsman high pressure


Check to make sure the condenser coil is clean, fan motor is running during freeze cycle. High Ambient temp, Ventilation, The higher the temperature entering the condenser coil the higher the head pressure. Fan motor failure, pressure switch failure. The cut out pressure varies 400, 450 or 500 PSIG. Water supply failure. not enough water running over the evaporator plate will cause high presser.

Ice machines compressor runs extremely hot.


This looks to be a Scottsman Ice machine so could be that your condenser fan motor isn't running or you need to clean the condenser which either of these could cause the compressor to be extremely hot. If it is over producing ice then you could try to turn down the bin level. If this doesn't fix your problem with over production then you may need to replace the bin level thermostat which can be located at the bottom of the machine. It is the one that has the knob on it. The other thermostat behind the control cover is the cube size control which routes to the back, top of the machine. The bin level control routes around under the bottom between the compressor and the case, then up and into the back of the cabinet. The silver colored scoop holder inside the machine to the right is where the bin level thermostat registers it's temperatures. It's not just a scoop holder. Let me know if you need more help. Thanks.

Hello mate re mv450


Check the ice thickness sensor for mineral buildup and clean if necessary. I downloaded the service manual from a site in New Zealand. If the Ice thickness sensor is free of scale make sure you are NOT supplying the machine with soft water.

Let me know if this solves your problem. I have been servicing Scotsman Ice Machines for over 38 years in the US. I will try to assist you any way I can. This particular model is not sold in my country.
