    It's a belly band heater right? Like a big hose clamp?

    You don't need it on that install...

    Hope this helps...

    Are you sure they didn't mean crank case regulating valve or oriface CRV CRO

    Seen plenty of freezers that needed them

    Unless this freezer sits in a low ambient area, there really is no need for a crank case heater.

    Did you ask those couple guys at work why they thought a heater was needed? If you haven't - I'd ask 'em if I were you.

    Remember, there are no dumb questions.......only dumb answers. If you don't ask why - you'll never know.

    Why would the refrigerant migrate to the compressor in the off cycle? Unless compressor location is below box temp? Correct?
