Fault Code 67
This is a problem with the Outdoor Fan Motor, where rotation is not detected, and could be result of either
Mechanical or Electrical failure.
??Check that motor is free to rotate and not seized.
??Check the motor is electrically sound, windings not Open or Short circuit.
??Check power output from PCB to fan motor.
??Check rotation feedback circuit.
More modern units use inverter fan motors, which are powered by a DC Voltage.
In reality these fan motors are AC fan motors with a small inverter-type circuit build inside. This inverter circuit is integrated with the fan motor and impossible to replace, you have to replace the entire fan motor.
Similar to inverter-controlled compressors, the speed of these fan motors can be changed to whatever is needed (within certain limits). In practice the change in fan speed is not ?continuous? but certain fixed speeds have been programmed inside the AC unit.
This type of fan control can be recognized by the 5 wires coming from the fan on a connector with 7 possible connections
These fan motors have 5 connections, power supply is 360VDC, and the speed is determined by a voltage ranging from 0 (0 rpm) to 5VDC (max speed) and a power supply for the internal electronics of 15VDC.
These motors are easy to identify from a wiring diagram, they always show them not connected to anything as the electronics are too difficult to draw on the diagram.

Detail of Hall Sensors
A Hall effect sensor works like a magnetic reed switch, one end is wired to a 15 Vdc supply and the other is the feed back to the PCB. As a magnet mounted on the rotor of the motor passes the hall sensor the reed switch closes momentarily and allows the DC signal to flow through it back to the PCB. The hall sensors have a resistance so the voltage fed back to the PCB will only be approximately 12V DC.
The pcb will know what speed the fan motor should be turning as it is also controlling the output of the
inverter, if there is a discrepancy between the inverter output RPM and the feedback from the hall sensors a fault will occur. Usually the fan will rev very fast for a few seconds then stop this indicates hall sensor problems.
Replace either Motor or Fan PCB as necessary.

Mówiąc krótko, jest kontrola obrotów wentylatora skraplacza. I nie sprzeczajcie się o słówka, bo czy robi to hallotron czy elektronika z hallotronem to i tak na jedno wychodzi. A chodzi o to żeby sobie pomóc, a nie zaraz ze złością wymądrzać.

W moim przypadku skraplacz (przy grzaniu to parownik :- ) raczej nie był zalodzony, a zgłoszenie dostałem po okresie silnych wiatrów. Jeżeli agregat pracował na 20%, to wentylator nie potrzebował dużych obrotów ... i dalej to mam na razie swoją teorię. Urządzenie będzie obserwowane.
