I bought a used Haier
Hi,
First, i will advice you check if the compressor and fan works when you plug the freezer, from your explanation, the click sound seems to me it could be a faulty compressor. Before testing the compressor motor, unplug the freezer to avoid an
electrical shock hazard. Also, if the compressor uses a capacitor, it
may contain a lethal electrical charge. Do not touch the terminals until
you have discharged the capacitor. The problem could also be a relay problem,. The function of the start relay is to momentarily energize the start
winding in the compressor motor and then cut power to the start winding
as soon as the motor is running. Most of the start relays on modern compressors are solid state and use a
special material whose resistance increases with temperature. So, as
current flows through the relay and the relay heats up, its resistance
increases to the point that the start winding is isolated from the rest
of the circuit.
A common failure of these relays is that the solid state material
"cooks" and breaks up, staying open and thus never allowing the start
winding in the compressor motor to energize. The end result is that the
compressor tries to start, usually you'll hear a humming noise, and
then, after a few seconds, the compressor's overload protector takes the
compressor offline with a loud CLICK.
Easy way to tell if the start relay is bad is by simply removing it
from the compressor's control pod and shaking it. If you hear any
rattling, it's fried.
