An interesting snippet from this site about resistance measurements on
Peltier modules:

Can you test a TE module with an ohmmeter? No - the DC voltage that an
standard
ohmmeter applies will cause a temperature change (Peltier Effect) which will
in
turn cause a voltage to be generated (Seebeck Effect) which will cause the
ohmmeter to read goofy (drifting, and even a 'negative' resistance. So, then
use the "diode test" position on the ohmmeter? No - even though a TE module
is
constructed of an array of N and P doped semiconductors there isn't an
actual
diode junction. A resistance test can be made with an LCR meter which
measures resistance using an AC voltage. Using a HP 4274A LCR meter I have
measured a few ohms for small modules and a fraction of an ohm for larger
ones.
While one does not usually see the resistance parameter specified on
manufacturer's data sheets it is probably not a bad of a check of a module's
health, especially if more sophisticated test methods are not available.
