    Just throwing out some "corrections" to the Supermarket Quiz.

    #2-The answer should be a,b and d. seen many a faulty defrost timer (gang clock) causing multiple system ice ups.

    #4- The answer cannot be all of the above as a rack that is "out of gas" would not short cycle, if it was low on gas it would short cycle.
    Watts New, Ohm My, I been Electrically Commutated. Are U2.

    We agree that the answer to #2 should have been g to include the defrost timer. I think that was actually a typo error.

    The #4 question will be reworded to say "low refrigerant" as opposed to "out of gas".

    Your score for that quiz will be updated accordingly.

    Thanks for the keen observations McCool!

    Cool, Ice.

    There are always many answers to Supermarket Questions, this quiz correctly portrays that ( but then again refrigeration service in general is like that across the board) I would personally rather work on a rack than a self contained unit. My day typically involves advising techs of various levels on what to look for. #1 reply from my end " Your there I'm not...you tell me what's wrong.

    I am new to hvac talk and am looking forward to getting the posts up to move into the pro-status. Looks like some great info at that level for any skill or experience level in this field. Started in residential service in mid 80's and then been in and out of hvac until this year.
