∗1: How to check the electronic expansion valve coil
Remove the connector for electronic expansion valve
from PCB. Measure the resistance value between
pins and check the continuity to judge the condition.
The normal products will show the following conditions:
1 No continuity between (1) and (2)
2 Resistance value between (1) and (3) is approx. 300 Ω
3 Resistance value between (1) and (5) is approx. 150 Ω
4 Resistance value between (2) and (4) is approx. 300 Ω
5 Resistance value between (2) and (6) is approx. 150 Ω
