Resistance Value :
120 (About)
If it is 0 (OPEN),replace Diode block.
CN12
Check Point 2: Check relay operation during normal operation
Check Point 2: Check relay operation during normal operation
1. If Relay does not operate (OPEN between COM – ON)
Check coil resistance value 120 (approx)
If the coil is cut off (open ), replace Power relay.
Check the terminal voltage of DC+ 12V at CN12 of control PCB.
If DC+12V does not appear, replace Control PCB
2.When relay does not release (Always ON even all indoor units are stopped).
:: Except the preheat control.
Remove connector to the relay and check the continuity between COM – ON.
It there is a continuity, the relay is shorted by welding, etc.
