Relay Chart
Relay Enable Not Closing
Check voltage between Relay Board CN01 pins 4
and 28.
• If 5 VDC is present, replace Relay Board.
• If 5 VDC is not present, replace Smart Board.
Buzzer
When Buzzer should be on, check voltage between
Relay Board CN01 pins 3 and 4.
• If 12 VDC is not present, the Smart Board is
not supplying the Buzzer operating voltage.
(See
Smart Board
troubleshooting section.)
• If 12 VDC is present, replace Smart Board and
Relay Board.
Troubleshooting
If all relays are not closing, see
All relays not closing
.
If one or more (but not all) relays are not closing, see
Single Relay Not Closing
,
If all Cooking relays are not closing, see
Relay Enable
Not Closing
.
If the Buzzer is not working, see
Buzzer
.
Note:
To gain better access to components, remove
the wires that plug onto the large relays on the
Relay Board. (See
Relay Board
.
) Cut the wire tie that
the Smart Board
CN103 wire harn ess (See
Smart
Board
.) is routed through.
All Relays Not Closing:
Check voltage between Relay Board CN5 pins 1
and 3.
If 120 VAC is not present, the wire between Relay
Board CN5 pin 3 and neutral output of Noise Filter 1
is open.
If 120 VAC is present, continue to next check.
Check voltage between Relay Board CN01 pins 2
and 4.
• If 12 VDC is present, replace the Smart Board.
• If 12 VDC is not present, Smart Board is not
supplying relay operating voltage. (See
Smart
Board
troubleshooting section.)
Single Relay Not Closing
Locate the inoperative relay in the Relay Chart in
next column.
Check voltage between the selected relay pin and
Relay Board CN01 pin 4.
• If 5 VDC is present, replace Relay Board.
• If 5 VDC is not present, replace Smart Board.
Note:
For situations where the above mentioned 5
VDC is not present, some relays operate loads that
can be controlled by the consumer from the Glass
Touch Assembly. If the in-operative relay is such,
make sure the option is selected at the key panel. If
it is, and the relay is still inoperative, check harness
between Glass Touch Assembly and Smart Board.
If harness is OK, replace Glass Touch Assembly and
Smart Board.
