Valve closure fail-
ure (leaky valve)
To check the LEV on the connection kit, check the indoor unit liquid pipe tempera-
ture that appears on the operation monitor on the outdoor unit's multi control board
while operating the indoor unit in question in the FAN mode and the other indoor
units in the cooling mode.
Replace the LEV
if the amount of
leakage is great.
(A)
Thermistor (RT12, RT13)
Normally, the LEV is fully closed while the unit is in the FAN mode. If the valve is
leaky, liquid pipe thermistor reading will be lower than normal. If it is significantly
lower than the ambient temperature, valve closure failure is suspected. If the
amount of leakage is insignificant, replacement of LEV is unnecessary unless it is
causing a problem.
Misconnections of
connectors or con-
tact failure
Perform a visual check for disconnected connectors.
Perform a visual check of lead wire color.
Disconnect the
connectors on
the control board
and perform a
continuity test.
