With meter set to diode test ... NEW (NEVER installed in your unit) and Suspect IC setting on a desktop (NOT installed in unit) ... measuring between any two pins of one (paying attention to which pin, red or black connects to) should result in very similar readings IF BOTH are GOOD. You'll want to be sure to test ALL combinations of pins.
