PH, PL, P5, P7, P8 Error Codes
Module Temperature Sensor Circuit Failure
Status:
During cooling mode, compressor will stop,
indoor fan will run. Heating mode all units
stop.
1. Replace outdoor control panel AP1
Fault & Status
Possible Causes
1. Measure the voltage on “L” & “N” on line
voltage, if it is higher then 265vac, correct
high voltage.
2.
If AC voltage is normal, measure the voltage
on the electrolytic capacitor on control panel
AP1, if it is normal replace the AP1 board.
High DC Bus-Bar Voltage
Status:
During cooling mode, compressor will stop,
indoor fan will run. Heating mode all units
stop.
P7
PH
1. Measure the voltage on “L” & “N” on line
voltage, if it is lower then 200vac, correct
incoming voltage.
2.
If AC voltage is normal, measure the voltage
on the electrolytic capacitor on control panel
AP1, if it is normal replace the AP1 board.
Low DC Bus-Bar Voltage
Status:
During cooling mode, compressor will stop,
indoor fan will run. Heating mode all units
stop.
PL
1. Refer to “H7” troubleshooting
Overcurrent Protection of Compressor Phase
Current
Status:
During heating mode, complete unit will stop
P5
Module High Temperature Protection
Status:
During cooling mode, compressor will stop,
indoor fan will run. Heating mode all units
stop.
1. After unit is de-energized for 20 minutes,
check for proper thermal grease on IPM
module of outdoor control panel AP1 and
contact is good. If this is OK, replace AP1
control module of outdoor unit.
