CLAIMS. CAUSES AND CHECK POINTS. HOW TO CHECK
1. Faulty start
1) No power on outlet.
2) No power on cord.
3) Shorted start circuit.
4) During defrost.
* Measuring instrument :
Multi tester
■ Check the voltage.
If the voltage is within ±85%
of the rated voltage, it is OK.
■ Check the terminal
movement.
■
Check both terminals of
power cord.
Power conducts : OK.
No power conducts : NG
■ Check both terminals of
O.L.P.
If power conducts : OK.
If not : NG.
■ Check the resistance of both
terminals.
At normal temperature 6 :
OK.
If disconnected : ∞.
Bad connection between adapter and outlet. (faulty adapter)
The Inner diameter of adapter.
The distance between holes.
The distance between terminals.
The thickness of terminal.
