Re: 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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

This machine has a cube size control. Which tells the machine when to go into a harvest. there is a harvest switch did you try to force it into a harvest and if you did, did it harvest. depending on ambient temperature from start of freeze cycle to harvest it should be making ice every 15 to 18 minuets and then go into a harvest. so start the ice machine and time it , run it for 18 minuets and force into a harvest. after ice drops check the ice bridge thickness. Bridge thickness should be about 3/16'' the ice dimple must not be DEEPER than 1/16". If this is good then we need to look at what is not working to harvest ice. The cube size control is a reverse - acting thermostat that controls the start of the timed freeze cycle. It must be set properly to prove the correct size cube bridge. When it is closed, an indicator light on the control board will be on. If you force it into a harvest and it harvest the ice with no problems and the ice is at the right thickness then replace the cube size control, but if dose not harvest the ice and you see the ice is at a good thickness and not to thick because if it is to thick it will freeze to every thing and will not drop. SYMPTOM. Unit freezes, but will not try to harvest. POSSIBLE CAUSE: Cube size control will not close; to check: Unplug water pump, switch unit OFF and then ON, in about 2 minutes the timed freeze light on the control board should be ON. PROBABLE FIX: If timed freeze light does not go ON, replace cube size control. SYMPTOM #2: Timed freeze light glows, but after 4 minutes unit dose not power hot gas nor purge valves Then replace control board.
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.
When the Ice Smells 1. Replace water filters every 6 months to avoid musty odors from getting into your ice. If you don't replace the filters, they become clogged with the chemicals they have been removing from the water. In addition to smelly ice, you may see a drop in water pressure if you have a water dispenser, and possibly a decrease in ice cube size.
2. Remove the cap from the new filter.
3. Place the cartridge inside the holder, and twist to the right.
When the ice smells...water & ice have tasted like ***** also.
Hello, Thank You for using FixYa. I will be helping you today.Check to make sure there is no ice cube stuck in the ice maker.Also check to make sure the fill tube coming through the back wall is not frozen.
Thank You and please rate my answer if it was helpful..
Well if your ice cube bucket is on the freezer door it self then it could be anything from the optics system to a bad icemaker to a water valve issue...if its located on the side freezer wall. the water valve could be bad or the i/m module/icemaker
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.
