[P19 error]

Is operation of 4-way valve normal? NO (Check the pipe temp., etc.

during cooling/heating operation.

YES

Are 1.3 to 1.6kΩ applied to	NO
	NO			Replace 4-way valve coil.

resistance value of 4-way valve coil ?
resistance value of 4-way valve coil ?

YES

Defective

Check temperature sensors.

TE sensor TS sensor Indoor TC sensor

Defective → Correct, replace

Check outdoor P.C. board operation.

(See the following description.)

OK

Check 4-way valve.

Defective → Replace

Check outdoor P.C. board.

Defective → Replace

Operation check direction of the outdoor P.C. board (In case of self-preservation valve)

1)Set the Dip switch SW804 as same as the following table and push SW801 for approx. 1 second. It enables you to check the exchange operation to cooling cycle or heating cycle.

•Only for approx. 10 seconds, the power is turned on.

•As the heat value of part (coil: resistance R700) is large, when checking the operation continuously, wait 1 minute or more until the next check. (There is no problem if a coil is not connected.)

2)After check, turn off all the Dip switches SW804.

Check by tester

Analog tester: Good article if over DC180V

Digital tester: Although in some cases, the value varied and indicated. If the maximum value is DC180V or more, it is good article.
