4.1.11 Hall IC Check
Check No.16 1. Check the connector connection.
2. With the power on, operation off, and the connector connected, check the following.
∗
Output voltage of about 5 V between pins 1 and 3.
∗
Generation of 3 pulses between pins 2 and 3 when the fan motor is operating.
If NG in step 1
Æ
Defective PCB
Æ
Replace the PCB.
If NG in step 2
Æ
Defective Hall IC
Æ
Replace the fan motor.
If OK in both steps 1 and 2
Æ
Replace the PCB.
The connector has 3 pins.
4.1.12 Main Circuit Short Check
Check No.29
Note: Check to make sure that the voltage between (+) and (–) of the diode bridge (DB1) is approx.
0 V before checking.
Measure the resistance between the pins of the DB1 as below.
If the resistance is
∞
or less than 1 k
Ω
, short circuit occurs on the main circuit.
