9.Operation stops after a few minutes and restarts, and this process repeats
Main cause Inspection method Normal value/condition Remedy
Dried-up electrolytic capacitor. Measure 290-VDC line voltage. 250 V or higher. Replace outdoor unit PWB.
Layer short-circuit in expansion
valve coil.
Measure resistance. 46±3Ω in each phase (at 20°C) Replace coil.
CAUTION:
If fuse FU1/FU5 (outdoor unit control circuit board) is blown, be careful of charging voltage in inverter electrolytic capacitor C5,C6:For CLC6101i 50/65
HE/ CLC6001i 25/35 E models;C8,C9:For CLC8101i 65 HE/ CLC8001i 25 /35 models).
To discharge stored electricity, unplug the power cord and connect the plug of a soldering iron (230VAC, 30W) between the positive and negative
terminals of inverter electrolytic capacitor C5,C6:For CLC6101i 50/65 HE/ CLC6001i 25/35 E models;C8,C9:For CLC8101i 65 HE/ CLC8001i 25 /35

[6] MALFUNCTION (PARTS) CHECK METHOD
1.Procedure for determining defective outdoor unit IPM/compressor
The following ow chart shows a procedure for locating the cause of a malfunction when the compressor does not start up and a DC over current
indication error occurs.
2.Diode bridge check method
Turn off the power and let the inverter electrolytic capacitor discharge completely. Then use a tester and check continuity.
When using a digital tester, the (+) and (-) tester lead wires in the table must be reversed.
Needle-type tester
Normal resistance value
(several M )
Value in ( ) is for digital tester.
