MEASURING THE COMPONENTS FROM THE MAIN PBC
You might measure the components from either connectors of Main PCB or directly on the component.
Example Main PCB
Measurements are best done from connectors on the main PCB where possible; check the values according to the
resistance value table for each components.
COMPONENT VALUES MEASUREMENT
Caution:
Always remove the plug from the power socket before touching internal components.
Circulation Pump:
From the Main PCB:
You can only measure the primary winding value from the main PCB. Resistance value of the primary winding must
be:
C
T
CIRCULATION PUMP
CN2.3 - CN2.9
117.9-
135.6 Ω
KN2.3 - KN 2.8
117.9-
135.6 Ω
Primary winding.
Secondary winding (from the component).
