11-10) If the solenoid in the ice-chute cover doesn’t work :
Is the S/N(solenoid) for
0.3 sec operated after 5 seconds
from power ON?
Start
Is MICOM No. 27 on
PCB maintaining High for 0.3 sec at the first
power ON?
Press Ice lever and keep it open.
Is the cover closed of
S/N after about
7
∼
10 seconds?
With the ice S/W ON
and ICE S/W on, ice-movement motor in F room?
Does C-E(between C and E)
of TR Q701 turn ON for 0.3 sec?
MICOM control port is normal.
Exchange the main PCB assembly.
The S/N control PCB assembly and
wire system have no trouble.
All the control system of cover ice-
route has no trouble.
Check the ICE S/W, and troubleshoot
the wire connection syste
m.
- Main PCB and the sensing section of
ice-S/W are normal.
- Check the operation of SSR71 and
Q701.
Check the stop lever and support
time-delay.
After replace TR Q701 and check SSR71 then
exchange the failed components or replace the
PCB assembly.
TR701 and SSR71 are normal

1) Check if the solenoid is unconditionally operated for 0.3 sec, independent of the Open/Close condition of cover ice-route, after
a lapse of about 5 seconds from power ON. (Before installation, the cancellation of cover ice-route open is enabled.)
2) Check if the connector in upper hinge section is hook-up correctly.
Preliminary check
Subject to the ice
S/W ON, do CN31 No. 2 and MICOM No. 45
get impressed 0V?
