2-5. Defrosting failure
Problems Causes
No defrosting. Heater does not generate heat as
ihe heating wire is cut or the circuit
is shorted.
1) Heating wire is damaged when
insetting into the evaporator.
2) Lead wire of heater is cut.
3) Heat ng w re at lead w re con acts
is cut.
Sucking duct and discharging hole
are clogged:
1. Impurities.
2. Ice.
Gap between Sucking duct and
Heater plate(Ice in the gap).
Wrong heater rating (or wrong
assembly).
Checks Measures Remarks
1. Check the resistance of heater.
0_2: Short. ,_2: Cut.
Tens to thousands _: OK.
2. Check the resistance between
housing terminal and heater
surface.
0_: Short. _;_: Cut.
Tens to thousands D: Short.
1, Confirm foreign materials. In case
of ice, insert the copper line
through the hole to check.
2. Put hot water into the drain
(check drains outside).
1. Confirm in the Sucking duct.
1. Check heater label.
2, Confirm the capacity after
substituting the resistance value
into the formula.
_=V "_ (V: Ratedvoltageof user country)
R (R: Resistanceof tester[_})
-- Compare P and level capacity.
Tolerance:±7%
Heating wire is short and wire is cut.
• Parts replacement: Refer to parts
explanations.
1) Push out impurities by inserting
copper wire.(Tum off more than
3hours and pour in hot water if
frost is severe.)
2) Put in hot water to mett down frost
3) Check the water outlet.
4) Push the heater plate to sucking
duct manually and assemble the
disconnected parts.
1) Turn off the power, confirm
impurities and ice in the gap, and
supply hot water until the ice in the
gap melts down.
2) Push the Heater plate to drain
bottom with hand and assemble
the disconnected parts.
Faults:replace.
- How to replace: Refer to main parts.
Seal the lead wire with
insulation tape and heat
contraction tube if the cut
lead wire is accessible to
repair.
