Check safety device.

➀

Disconnect safety device connector (CN12, 2P, WHT) from outdoor unit PCB, and measure resistance on the
safety device.

In case of abnormality 

➞

Replace temperature fuse or temperature limiting switch.

Normal

1 

Ω

or less

*

Use a circuit tester (set to 

Ω

range).

In case of abnormality 

➞

Replace outdoor unit PCB.

In case of abnormality 

➞

Replace outdoor PCB.

➁

Remove flame rod connector, and measure direct current between connector and PCB.

Caution: The flame rod retains electromotive force immediately after combustion ceases, therefore measure-

ment should be made while the equipment is cool.

Check flame sensor probe.

➀

Measure voltage of alternative current between flame rod connector (1P, CN17) and ground.

Normal

AC 104 – 126 V

Normal

DC 1µA or less

*

Use a circuit tester (set to AC range).

*

Use a circuit tester (set to DC range).

Normal

AC 104 – 126 V

1) Check ignition transformer.

➀

Check if ignition wires are disconnected or have voltage leak.

➁

Measure AC voltage between the connectors (CN07) to the ignition electrode.

In case of abnormality 

➞

Replace outdoor unit PCB.

If voltage is normal but sparking noise cannot be heard, replace the ignition electrode.

Caution: If the ignition wires are disconnected, connect them by pushing them in firmly.

2) Check gas valve (GV1).

➀

Measure DC voltage at the connector (CN08) of electromagnetic valve (under heating operation, during com-
bustion).

In case of abnormality 

➞

Replace outdoor unit PCB.

Normal

WHT – WHT  DC 90 – 120 V

*

Use a circuit tester (set to AC range).

*

Use a circuit tester (set to DC range).
