FAULTS
6 720 803 687 (2012/11) 65
U2 (3) Compressor temperature too
high
Faulty if temperature sensor TH32
exceeds 125 °C or 110 °C for
5 minutes.
See U2 (2), but replace temperature sensors TH4,
5 and 6 with temperature sensor TH32
See U2 (2)
U3 Open / short circuit on hot gas
temperature sensor TH4 or
compressor temperature sensor
TH32
If the hot gas temperature sensor
TH4 cannot capture any
temperature ( 3 °C) or indicates an
infinite resistance (> 217 °C) whilst
the compressor is working, fault
display “U3” will be shown.
This function is not available in the
following situations:
• In the first 5 to 10 minutes after
the compressor starts
• At the end of the defrost mode
• When defrost mode is running
Poor connection/contacts or terminal loose at the
cables and plugs on the PCB.
▶ Check and repair plug and contacts of the temperature
sensor of the PCB.
▶ Check temperature sensor connecting leads for cable
breaks or the like.
Faulty temperature sensor. ▶ Check temperature sensors TH4 and TH32 with service
tool (7-716-161-051).
Faulty external unit PCB ▶ Replace faulty external unit PCB.
U4 Open / short circuit on external
unit temperature sensors (TH3,
TH32, TH33, TH6, TH7 and TH8)
If a temperature sensor does not
measure any resistance (0 ) or
measures an infinitely large
resistance (8 ) when the
compressor is running, fault display
“U4” is shown.
Poor or loose contacts at the cables and plugs on
the PCB.
▶ Check and repair plug and contacts of the temperature
sensor of the PCB.
▶ Check temperature sensor connecting leads for cable
breaks or the like.
Faulty temperature sensor. ▶ Check temperature sensors TH32 with service tool (7-716-
161-051).
Faulty external unit PCB ▶ Replace faulty external unit PCB.
U5 Temperature fault on inverter
radiator panel
If the temperature at TH8 (heat
deflector) reaches or exceeds the
specified value, fault display “U5”
will be shown.
• RP35 84 °C.
Blocked fan motor. ▶Check fan motor.
Fan motor fault.
Ventilation and extract air apertures dirty or
blocked.
▶ Check and clean ventilation and extract air apertures.
Rising outside temperature. ▶ Check if causes other than the weather are responsible for
the temperature increase.
Upper temperature limit 46 °C. Switch the supply voltage
off and on again.
▶ Within 30 minutes, check if fault display “U5” is shown
again.
If fault display “U4” is shown instead of “U5”, follow the
descriptions provided for “U4”.
Faulty temperature sensor. ▶ Check resistance of temperature sensor TH8 (should be
between 39 and 105 k ).
▶ Replace faulty temperature sensor.
Faulty input circuits (supply voltage) on external
unit power circuit board.
▶ Replace faulty external unit power circuit board.
Faulty drive circuitry of external unit fan. ▶ Replace faulty PCB.
U6 Power module in inverter circuit
faulty
If overcurrent is detected in the
inverter circuit (“UF” or “UP” is
shown), the inverter circuit is faulty
and fault display “U6” is shown.
Faulty ball valve (not completely open). ▶ Check and completely open all ball valves.
Reduced supply voltage. ▶ Check supply voltage (mains side).
Poor connection/contacts or terminal loose on
compressor supply cable or phases swapped.
▶ Check and correct compressor wiring.
Faulty power circuit board. ▶ Replace faulty external unit power circuit board.
Faulty compressor. ▶ Replace external unit.
