In soft serve and frozen yogurt machines, the logic board X36641SER2Refurbished Gen 2 Logic Board This item is sold with exchange...measures the viscosity of the product by monitoring the amp draw of the beater motor. When the machine reaches the set point, it cycles off and the product is ready. In auto mode, you can only adjust product viscosity, temperature in the freezing cylinder is not monitored.
The power board measures the amp draw. L1 power supplied to the beater motor goes through the power board on the beater terminals. Single phase and three phase units use the same Softech control, so the power board allows for different amp draw ranges. A jumper on the power board determines the amp draw range. Place the jumper on the pin that corresponds to the amp draw of the beater motor when the product is at the desired viscosity.
Setting Viscosity Adjustment
1. Place an amp probe on one of the L1 leads on the beater terminal on the power board.
2. Turn the viscosity adjustment screw to the "MAX" position.
3. With the freezer properly primed, press "AUTO".
4. During the freezing process, draw samples and inspect the product appearance. When the desired product viscosity and appearance is achieved, note the beater amperage.
5. Press "AUTO" to cancel the refrigeration cycle.
6. Using the chart, set what range the beater motor amperage falls into and place the jumper on the corresponding pin.
Viscosity Control Chart
2.4 pin - 1.2 amp to 2.4 amp
5.0 pin - 2.5 amp to 5.0 amp
8.0 pin - 5.7 amp to 11.2 amp
7. Press "AUTO". When amperage reaches the noted draw, turn the viscosity adjustment screw SLOWLY until the unit cycles off.
8. Draw several samples to verify the product and amperage when the machine cycles off remain consistent.
To increase viscosity, or make the product harder, turn the dial clockwise towards maximum. Important: The dial only turns a limited amount if it stops turning do not force it.
To decrease the viscosity, or make the product softer, turn the dial counter-clockwise towards minimum. The dial only turns a limited amount do not force it once it stops.
We recommend you only turn the dial about 1 hour on the clock, at a time. Once you have made your adjustment, pull the handle to start a new cycle, when the machine cycles off check the product again. X36641SER2Refurbished Gen 2 Logic Board This item is sold with exchange...
It could be a couple things. The most common is worn down scraper blades. Try new ones first. Worn scraper blades don't scrapers the cylinder walls and the ice cream that's stuck on the walls acts like insulation and it will take a lot longer to freeze this ice cream. If that doesn't solve the problem then you are likely low on refrigerant on that side. Your machine measures the viscosity by reading the amp draw of the beater motor. The harder the ice cream gets, the harder the motor works. If the ice cream isn't getting hard enough because of one of the reasons above, your machine wont shut off.
Viscosity adjustments should not have to be made frequently on these machines. If you change products a lot, such as flavors of yogurt, minor adjustments may be required. If your machine uses 3 phase electricity and it machine has been moved or any electrical work performed you may want to check the beater rotation, the beater should rotate clockwise inside the barrel viewing from the front, if you look at the gear box from the back, the pulley should be turning clockwise as well. Otherwise, there is a fine tuning potentiometer on the control, you must remove the front cover to see it. Clockwise is colder/thicker. I recommend small adjustments. It is best to read the amp draw on the motor to see what type of amps it is drawing. If your mix is soft and your motor is drawing 4 amps, you may have another type of problem such as a bad motor. The board and control can also fail giving these problems. There are many things to check in addition to these. Hope this will help you get started.
Check that all gears are in good working order. The paddlewill not turn properly and the motor will not run if the gears are worn ordamaged gears. Inspect the paddle for damage and replace if necessary. You alsomay need to replace worn or damaged gears in the motor. Lubricate the motor,drive shaft and motor bearings.
Hope this will help you. Good Luck.
You need a good simple recipe. So here is one. (This is an unpasteurized recipe unless you boil the blended strawberries, wash the berries very well if you don't)
1 lb fresh strawberries (ripe is better) 3/4 cup sugar (most folks double this but i prefer the taste of strawberry) 3/4 cup whipping creme 2 1/4 cups milk (2%) 1 tsp lemon juice
Liquefy the strawberries in your blender. (Boil now if pasteurizing) and add the rest of the ingredients and blend. You
now have enough Ice cream mix for two partial batches. Divide mix in
two equal portions. You should have enough to fill machines bucket 1/2 -
2/3 full. IMPORTANT Do NOT have more or less in the bucket as the machine screws up with more or less of any mix. Insert Paddle and put noisy grey power arm on top. Add a 2 inch thick hardcover novel on top of arm above bucket. Add a heavy Soup can on top of this book (I recommend Habitant French Canadian Pea Soup 28 fl oz size).
Set timer to 40 minutes. Leave room as it is a noisy little beast machine.
Come back and check just before it is done. If still too liquid add 5 minutes to timer.
Empty into bowl and add 2nd half of mix to bucket. Clean
the dimple on bottom of mixer paddle before putting back in bucket.
This batch should take 5 minutes less as compressor is already cold.
The book and Soup can are essential to keep the silly beasts power arm from lifting up too early.
Yes I too would guess motor burnout ( Motor is very overworked as ice cream hardens) You could replace the motor but I would suggest buying a new one because the cost of a major repair like that may very well cost more then a new unit!
I hope I answered the question to your satisfaction!

Sounds like the belt might be slipping prematurely. I'd try cleaning the belt and all the pulleys with an alcohol based solvent or rubbing alcohol (clear) to remove any excess oils that might cause slippage and see if that helps Is there any type of belt tension adjustment? If so, also try tightening the belt.. If the problem persists, you probably need to replace the belt.
If this helps, after the churning stops, remove the paddles and cover the top with plastic wrap or wax paper and allow the mixture to "firm up" in the ice bucket nother 10-15 mnutes, and then enjoy a great old-fashioned treat!
Hope this is a help, let us know how it goes, and good luck!
All i can suggest is cleaning the contacts. Clean the metal prongs and the two holes they go into.
UNPLUG THE MACHINE
Use a q-tip cotton swab dipped in hydrogen peroxide or rubbing alcohol ... not both. After cleaning one hole wipe off any excess fluid before cleaning the other hole. These holes are a natural for catching stray drips of food or other kitchen goo.
