Disconnect the BL3 Connector
from the main PCB and measure
the resistance between BL3-1
(RD) and BL3-2 (PK). Is the
resistance 1.5k-2.5k
Ω
?
Measure the resistance between
BL3-1 (RD) and BL3-3 (WH). Is
the resistance 1.5k-2.5k
Ω
?
Disconnect the YL3 connector
from the main PCB. Measure
the resistance between YL3-1
(GY) and YL3-3 (BL). Is the
resistance <1
Ω
?
The flame sensor is closed and the ignitor is OK.
• Perform the functional test above.
• Check all wiring and connectors to gas valve components.
• Check gas supply.

Measure the resistance between
YL3-3 (BL) and the blue wire on
the black tab relay. Is the
resistance 100-800
Ω
?
