166 Part Number 80-1230-9 10/10
To verify coupling/auger RPM (revolutions per minute):
1. Verify line voltage is within 10% of ice machine
nameplate rating when low RPM is suspected.
2. Verify the gear motor run capacitor is functional.
3. Place identifying mark on coupling.
4. Count coupling revolutions for 2 minutes.
5. Divide coupling revolutions by 2 (example:
31 coupling revolutions ÷ 2 = 15-1/2 RPM).
Minimum revolutions per minute:
QF0400 = 9 RPM
QC0700 = 15 RPM
QF0800 = 15 RPM
QF2200/QF2300 = 11.6 RPM
