F-1000M GEAR MOTOR CHECKOUT<br />
NORMAL AMPERAGE: The amperage for the F-1000M<br />
gear motor should be 0.6~1.0 amps with no load and 1.0~1.4<br />
amps when making ice.<br />
Answer the following questions to discover the possible<br />
cause for your failure:<br />
1. Is Ambient Temperature above 45 degrees F.<br />
2. Does the unit have the Wrong Extruding Head. Check<br />
the Extruder Type. Is it a Flaker or Cubelet style. (The<br />
cubelet style head will have smaller openings for the ice to<br />
extrude.)<br />
3. Does the unit have the Wrong Cutter. The cutter should<br />
match the extruding head style. Flake or Cubelet.<br />
4. Do you have a Damaged Extruder. Look for following<br />
imperfections. A. Dents B. Fins Bent<br />
C. Scale D. Other Resistance<br />
5. Does the unit have the Correct Auger. Is the auger a<br />
dual flight auger? (Double Spirals) Check the parts breakdown<br />
for the correct auger style.<br />
6. Check the Voltage Supply and circuit amperage. Is this<br />
unit on it’s own dedicated circuit? The supply voltage<br />
should be within +/- 10% of the rated voltage when the unit<br />
is making ice.<br />
7. Check the Running Voltage at the gear motor. (While<br />
the unit is making Ice.)<br />
8. Inspect bearings for wear. ( Use bearing gauge ) Are<br />
the Bearings OK? If the upper bearing is worn, both bearings<br />
should be replaced.<br />
9. Check Evaporator Cylinder/ Barrel for signs of scoring.<br />
10. Is there any condensation dripping onto the Gear Motor<br />
windings? If yes, find the source and take action to<br />
stop the moisture.<br />
11. Is the galvanized shield mounted over the motor assembly?<br />
12. Verify that you have the proper Gear Motor Capacitor.<br />
13. Is the Gear Motor Locked. Check motor winding resistance.<br />
2. WRONG GEAR MOTOR OVERLOAD / FUSE:<br />
Check fuse size. Has the original overload reset been replaced<br />
with the fuse kit? The M_F Flaker requires Bussman<br />
GMD 1.5A Fuse P/N 4A0893-04. The M_F-C Cubelet<br />
requires Bussman GMD 2.0A Fuse P/N 4A0893-05. This<br />
fuse is a slow blow type. Replacing it with a standard fuse<br />
will cause the fuse to blow again.<br />
