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