Problem
1. Machine has entered Low Temperature Protection. When the
temperature of the freezing cylinders has dropped below 10°F (-12°
C) while the machine is in Auto Mode, the compressor will turn off
and go into Discharge Mode.
Solution
1. In Auto Mode, the machine automatically detects the temperature
of the product in the freezing cylinder via temperature probes. This
Low Temperature Protection is to prevent the product from over
freezing and possibly freezing solid. If over freezing occurs, turn the
machine off for 10 minutes and then decrease the firmness setting
to a lower number (change from 7 to 4, for example) and restart the
machine. If problems persist, contact an authorized service techni-
cian.
Problem
1. Breaker in the side panel access door is tripped.
2. Frozen product in the freezing cylinder or object restricting the
rotation of the beaters or problem with beater motor. Check for
loose wiring, overheating, or faulty starting components.
3. Faulty rotational movement sensor(s).
4. Rotation sensor(s) disconnected at the main circuit board.
Solution
1. Switch breaker(s) to the upright position.
2. Set Auto Mode OFF and decrease the temperature setting to
soften product (See Section 5). Be sure product is not completely
frozen solid inside the freezing cylinder before restarting.
