The wire colors from the appliance is one black and one black with a white stripe. My replacement cord has one black wire and one red one. Which would be the correct assumption for the right polarity. Red to black or red to black and white?

Black will represent (+) Black with white strip (-)
Black will represent (+) Red (-)

If the appliance is only a resistive circuit like a heater, it won't make any difference. If there's a motor or electronics inside, the polarity might be important. The best solution is to hook it up with the original cord and check it with a voltmeter for polarity. If that's not possible, the best guess is black to black, red to Bk/W. Connect it momentarily to see whether it functions correctly or just creates a smoke cloud................!
Good luck!

If you are not sure, just measure the polarity with a multi-meter. Just be sure your meter is setup to read voltage and not current so you don't short anything.

Doesnt matter either way is fine . Worse case it runs backwards.
