4. Removing the thermistor <2-Phase Pipe> (TH6)
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Disconnect the connectors, TH6 and TH7 (red), on the
controller circuit board in the electrical parts box.
Loosen the fastener and the wire clip on the electrical parts
box and unbind the lead wires.
(4) Loosen the clamp for the lead wire in the top of the electrical
parts box.
(5) Pull out the thermistor <2-Phase Pipe> (TH6) from the
sensor holder.
Note: When replacing thermistor <2-Phase Pipe> (TH6),
replace it together with thermistor <Ambient> (TH7)
since they are combined together.
Refer to procedure 5 to remove thermistor
<Ambient>.
5. Removing the thermistor <Ambient> (TH7)
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Disconnect the connector TH6 and TH7 (red) on the
controller circuit board in the electrical parts box.
Loosen the fastener and the cable strap on the electrical
parts box and unbind the lead wires.
(4) Loosen the clamp for the lead wire in the top of the
electrical parts box. (See Photo 5)
(5) Pull out the thermistor <Ambient> (TH7) from the sensor
holder.
Note: When replacing thermistor <Ambient> (TH7),
replace it together with thermistor <2-phase pipe>
(TH6), since they are combined together.
Refer to procedure 4 to remove thermistor <2-phase
pipe>.

6. Removing the thermistor <Liquid> (TH3) and thermistor
<Comp.Surface>(TH32)
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Disconnect the connectors, TH3 (white) and TH32 (black) on
the controller circuit board in the electrical parts box.
Loosen the fastener and the cable strap on the electrical
parts box and unbind the lead wires.
(4) Loosen the clamp for the lead wire in the top and rear of
the electrical parts box. (See Photo 5)
(5) Pull out the thermistor <Liquid> (TH3) (See Figure 2) from
the sensor holder.
[Removing the thermistor <Comp.Surface> (TH32)]
(6) Remove the top damper, then pull out the thermistor
<Comp.Surface> (TH32) from the holder of the compressor
shell.
(7) Loosen the clamp on the separator and unbind the lead wires.
