Fan Motors - Zanussi ZS12V70CCHI Service Manual

Compressor discharge line sensor: measures the temperature value of the gas which the compressor discharges. Its duty in the
system is to help decrease the cycle of the compressor when the compressor discharge gas temperature goes above the critical level.
Condenser pipe sensor: Measures the temperature of the gas at the condenser outlet. Its duty in the system is to prevent icing of
the condenser in heating and ensuring that the gas temperature is below the critical level in cooling.
Outdoor temperature sensor: Air conditioners' operating environment temperatures are predetermined. When these temperatures
are exceeded, it helps prevent damage to the air conditioner by decreasing the cycle of the compressor.
How to do a sensor measurement
• Sensor should be disconnected from the device.
• The temperature in the environment to be measured should be measured with an appropriate thermometer.
• The sensor from which a resistance value will be obtained should be kept in the environment for 5 min. (until the temperature of
the sensor equals to the environment temperature)
• Resistance values should be taken with an appropriate measuring tool. (The measurement method is shown in the below figure.)
The table attached is compared. If the values obtained match, sensor is robust.
9.2.3 Solenoid coil measurement
Robustness of the coil: Measurement tool probes are connected to its two cables as shown in the below image and resistance values
are taken. The value on the display (1,307 kΩ 25°C) shows that the coil is robust. The next measurement is to detect a problem in
the insulation of the coil. To understand this, one probe is connected to one of the ends, and the other probe is touched to the metal
body of the coil. If a value is shown on the display, the coil is faulty.

9.3 Fan Motors

9.3.1 Indoor unit fan motors (AC - BLDC)
As indoor unit fan motors, asynchronous motors and BLDC motors whose cycle can be controlled are used. The control of the cycle
in AC motors is performed through the relay or triac on the electronic board. It ensures that the cold air obtained in the evaporator is
given to the outdoor environment and, at the same time, the hot air in the indoor environment is passed through the evap.
Indoor unit fan motors used in 2020 are given in the table below.
