YN
Go to Flag 8 (Fl
ag 18 w/ TAG P31) on BSD 10.2 and check for an open circuit.
If the wires are OK, replace the IOT Drive PWB (PL 9.2).
There is approximately +4.3 VDC between P/J105-4 on
the SSR and GND when
the lamp is off.
YN
Check for an open wire at pin 4 of P/
J1
05. If OK, replace the SSR (PL 9.3).
Enter dC330 010-030 Heat Roll Heater Rod On. Press Start. The voltage at P/
J105-4 dec
reases to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 9 (Fl
ag 19 w/ TAG P 31) on BSD 10.2 and check for an open circuit. If the
wires are OK, replace the SSR (PL 9.3).
Replace the AC Driver PWB (PL 9.3).
Open the drawer. Remove the cheater on the Front Door Interlock. Measure the resistance
across
the Heat Roll Heater Rod. The resistance is less than 10 Ohms.
YN
Replace the Heat Roll Heater Rod (PL 8.3).
Check the resistance across the Heat Roll Thermostat. The value is less than 10 Ohms.
YN
Replace the Heat Roll Thermostat (PL
8.
4).
Switch off the power. Disconnect the connectors to the
Heat Roll Thermostat, AC Driver PWB,
SSR, and the IOT Drive PWB. Check the connectors for broken, bent, or dirty pins. Discon-
nect, then reconnect, the connectors several times to remove oxidation. TAG P31 i
s present.
YN
Go to
Fl
ag 10 and
Flag 13 on BSD 10.2 and check for an open circuit. If the wires are OK,
replace the AC Driver PWB (PL 9.3). If the problem continues, replace the SSR (PL 9.3).
If the problem persists, replace the IOT Drive PWB (PL 9.2).
Switch on the power. There is +5 VDC from J73 to
J74 o
n the Surge SSR.
YN
There is +5 VDC from J73 on t
he
Surge SSR to frame ground
YN
Go to Fl
ag 28. Check
for an open circuit. If the wire is OK, replace the AC Driver
PWB (PL 9.3). If the problem continues, replace the Surge SSR (PL 9.6).
Go to Flag 30.
Check for an open circuit. If the wires and the AC Driver PWB (PL 9.3) are
OK, replace the IOT Drive PWB (PL 9.2).
Switch off the power. Disconnect P/J70. T
he resistance from J70-1 to J70-2 is 55 ohms +/-
20%.
YN
Replace Surge Resistor (PL
9.
6).
Go to Flag 20, Fl
ag 23, and Flag 27 on BSD 10.2 and check for an open circuit. If the wires are
OK, replace AC Driver PWB (PL 9.3). Replace the Varistor PWB (PL 9.6) if the problem per-
sists.
If the problem continues,
replace t
he SSR (PL 9.3), then the IOT Drive PWB (PL 9.2).
