DIAGNOSING A CONDENSING UNIT
THAT WILL NOT RUN
If the ice machine water pump is not energized, refer
to “Diagnosing an Ice Machine that Will Not Run.
1. Verify primary voltage is supplied to ice machine
condensing unit and the fuse/circuit breaker is
closed.
2. Test for 24 vac at terminals C & V - Replace
transformer if 24 vac is not present.
3. Verify the low-pressure control is closed by testing
for 24 vac @ terminals C & LPC.
4. Verify wires are intact and ice machine is calling
for cooling by testing for 24 vac @ terminals C &
HPC1.
5. Verify the high-pressure control is closed by
testing for 24 vac at the contactor coil terminals.
6. Verify the contactor contacts are closed and line
voltage is present across all lines.
7. Refer to compressor diagnostics.
