12. COMPONENT: STRAINERS
DESCRIPTION:
Mesh strainers are required on the inlet and outlet of the
electronic expansion valve to prevent debris from entering
the valve.
TROUBLESHOOTING:
Normally strainers should not have any temperature
differences between the inlet and outlet as shown in item 1
below. However if a temperature differences is detected
then the strainer may be clogged. If strainer is clogged,
replace strainer.

13. COMPONENT: REACTOR (CHOKE)
DESCRIPTION:
Choke coils are inductances that isolate AC frequency
current from certain areas of a radio circuit. The reactor
(coke) depend upon the property of self-inductance for its
operation. Chokes can be used to block alternating current
while passing direct current.
TROUBLESHOOTING:
Inspect reactor (choke) for loose connections or burnt
windings.

14. COMPONENT: FERRITES
DESCRIPTION:
Ferrites are chemical compounds consisting of ceramic
material with iron oxide as their principle component. Some
ferrites have magnetic properties and are used to make
permanent magnets and ferrite cores for transformers which
can be used in various applications.
Electronic cabling and wires, by virtue of their length-to-
width ratios, are perfect natural antennas. In the presence of
high-speed microprocessor signals, cable will conduct,
radiate, and receive unwanted high-frequency interfering
signals. Control of radio-frequency (RF) interference can be
ensured by the proper placement of an insertion-loss
device, such as a ferrite suppressor. They are consistently
stable over time and and over wide temperature ranges, and
provide RF suppression without high eddy-current losses.
