3.4.3 Condenser Fan
The condenser fan rarely needs replacement. A bent fan blade,
debris blockage, or loose connection can often be corrected by
hand. In the rare case of fan motor failure, replace the fan.
Service check
If the fan does not run when powered, it will need to be replaced.
To verify motor failure,
disconnect
the fan from the compressor
and measure the resistance across its two connectors. Normal
resistance is between 50 and 150 ohms. If the motor has burned
out, the resistance will be very high (open).
