1. Check the circuit in the power transistor module.
2. Is the outdoor fan revolving ?
1. Is the discharge outlet of the outdoor unit clogged ?
1. Measure the resistance of heatsink thermistor TH6 on the heatsink
in outdoor unit.
2. Check rotation of the fan motor in outdoor unit.
3. Is the power supply voltage at least 198V at full power operation ?
1. Measure the resistance of thermistor TH2 on the outdoor unit
(see Figure 3).
1. Replace power transistor
module
1. Clear the discharge outlet.
11 times Power factor module error
1. CHeck wiring of power factor module.
1. Replace the power factor module.
1. Reattach.
2. Reattach CN101 and CN102,
otherwise replace power transistor
module assembly or outdoor control
board assembly.

1. Has not if escaped from the compressor CN6 ?
2. Is the power supplied of 15V and 6V supplied to the IPM PWB.
1. Replace the heatsink thermistor.
Open circuit of the
heatsink thermistor.
1. Are the connectors of the heatsink thermistor in outdoor unit well
attached ?
2. Measure the resistance of thermistor TH6 on the heatsink.
(See Figure 3).

1. Reattach.
2. Replace the heatsink thermistor.
1. Replace the outdoor control board
assembly
(Current transformer wire break.)
1. Reattach.
2. Replace the outdoor thermistor
assembly.
1. Replace the outdoor thermistor
assembly.
1. Clear the discharge outlet.
2. Assure power supply voltage.
3. Refill to rated amount.
4. Replace the outdoor ther-mistor
assembly.
5. Replace the indoor control board
assembly or only TH2.
1. Can voltage be detected at the current transformer on the outdoor
unit control board?
1. Is the connector of the outdoor unit thermistors well attached ?
(see Figure 3).
2. Measure the resistance of thermistors TH1 and TH2 on the
outdoor unit (see Figure 3).
1. Is the discharge outlet of the outdoor unit clogged ?
2. Is the power supply voltage at least 198 V at full power operation ?
3. Check for refrigerant leaks at the tubing connections.
4. Measure the resistance of compressor thermistor TH1 on the
outdoor unit (see Figure 3).
5. Measure the resistance of heat exchanger pipe thermistor TH2 on
the indoor unit (see Figure 1).

Note: 1. Normal : Only the timer lamp blinks. Error : Displayed by blinking of run
lamp (above table).
2. If the power plug is removed from the outlet or the breaker is switched to
"OFF", the self-diagnostic memory will be erased.
