RELAY (BREWERS W/BREW LOCKOUT)
FIG.18 RELAY
P1731.55
Location:
The relay is located on the front part of the com-
ponent bracket, mounted on the top of the timer
bracket.
Test Procedures:
All Models Except 230V - CE Models
1. Disconnect the brewer from the power source.
2. Disconnect the wires from relay terminals "A" &
"B". Check for continuity between terminals "A" &
"B".
If continuity is present as described, reconnect the
wires to terminals "A" & "B" and proceed to #3.
If continuity is not present as described replace the
relay.
3. Disconnect the wires from relay terminals 2 & 7.
4. Check for continuity across terminals 2 & 7.
If continuity is present as described, reconnect the
wires to terminals 2 & 7 and proceed to # 5.
If continuity is not present as described, replace the
relay.
5. Disconnect the wires from relay terminals 5 & 7.
6. Check for continuity across terminals 5 & 7 by
manually closing relay contact. Continuity must
not be present when contact is released.
SERVICE (cont.)
If continuity is present as described, reconnect the
wires, the relay is operating properly.
If continuity is not present as described, replace the
relay.
230V - CE Models
1. Disconnect the brewer from the power source.
2. Disconnect the black wire from relay terminal "A"
and the red wire from relay terminal "B". Check
the voltage across the black and red wire with a
voltmeter. Connect the brewer to the power source.
The indication must be 230 volts ac.
If voltage is present as described, proceed to #3.
If voltage is not present as described, refer to the Wir-
ing Diagrams and check the brewer wiring harness.
3. Disconnect the brewer from the power source.
4. Check for continuity across relay terminals "A" &
"B"
If continuity is present as described, reconnect the
wires to terminals "A" & "B" and proceed to #5.
If continuity is not present as described, replace the
relay.
5. With the thermostat in the "ON" position and the
relay engaged disconnect the brewer from the
power source.
6. Disconnect the blue wires from relay terminals 1
and 7. Check for continuity across terminals 1 and
7.
If continuity is present as described, proceed to #7
If continuity is not present as described, replace the
relay.
7. Turn the thermostat to the "OFF" position, con-
nect the brewer to the power source and turn the
thermostat back to the "ON" position. Continuity
should not be present across terminals 1 & 7.
If continuity is not present as described, the relay is
operating properly.
If continuity is present as described, replace the
relay.
