Troubleshooting
Samsung Electronics 4-53
4-3-33 : Suspension of starting due to Compressor discharge temperature sensor
/ Top temperature sensor
1.
Cause of problem
Is the resistance
value normal for the
Compressor discharge Temperature sensor/
Top temperature sensor?
(Refer to “NOTE 1”)
Auto Trial Operation
Are all service valves open?
Are the Indoor Unit
and Outdoor Unit EEV normally
operating?
Are there
any blockage inside the pipe?
(filter etc.)
Check the refrigerant amount.
Replace Compressor discharge temperat
-ure sensor / Top temperature sensor
Open the Service Valve
Check the relevant EEV
Pipe inspection
Connect S-net and Manifold Gauge.

Judgment
Method
 When value of Compressor discharge temperature sensor / Top temperature sensor is checked at 120ఁ or more
Cause of
problem
 Refrigerant shortage
 Electronic expansion valve is blocked.
 Service valve blocked
 Defective discharge temperature sensor
 TOP temperature sensor defective
 Blocked pipe and defective
 Discharge check valve leaking on outdoor unit that is off
