Condenser: Testing and Inspection
Inspecting Condenser Continuity:
1. Disconnect noise filter/condenser electrical connector.
2. Measure noise filter resistance between B and C terminals of noise filter/condenser connector using a digital volt/ohm meter. If the noise filter resistance is not about 2.2K ohms, replace the noise filter.
3. Measure condenser for continuity between A and B terminals of the noise filter/condenser using a digital volt/ohm meter. If the condenser is conductive, replace the noise filter and condenser.
