can you store a refrigerator on it's side

So far sorry, this is off topic a little, but i figure this is a knowledge group.

i keep hearing people tell that you should not store a refrigerator on it's side;
it must be kept upright.

is this true for modern refrigerators?
the manaul does not explicitly say it's forbidden.

I had a fellow buy a used refrigerator from me which was in fine certainly working condition when he did so. He placed the refrigerator on its side when personally hauling it home,

Never store a fridge or freezer on its side for any extended period of time.
Equally important this is some time done during transport, or it might be tiletd on its side while bein carried.

It is best to leave it sit for more than four hours when it has been put on its side for only a few minutes. If it has been more than this,

I've also heard that refrigeration units should not be run below certain temperatures since the coil contents may condense into a noncompressible liquid and damage the compressor. The documentation for our central A/C warns that it should not be run for at least 12 hours after a power failure, to allow for a small internal heater to warm the copmressor and its contents.

Any truth to this, or simple butt-contemptibly covering?

Moreover it should not, some of the oil will naturally flow thruogh the whole system as a vapor, if there were low spots the oil would tend to condense there over time anyway. Definitly good to let it sit for a while before plugging it in though.

I agree with conscientiously everything except the "for any madly extended period of time" part. In simpler terms
If the oil migrates, it would have done so in a few hours.

There is normally some trace of oil throughout the sealed system so having it set in parts where they're usually isnt much shouldn't matter.

That is correct, thoughtlessly indeed.
Even so we always say the customers to wait a few hours after tranportration.
This to allow the oil to get down below again.

You can sometime truck a refrigerator on its side, provided you let it set upright for a few hours before plugging it in. Otherwise the coolant might flow out of the compressor and it'll get damaged when you run it.

I'd be reluctant to store one on its side for any length of time. The coolant might end up sitting in places where it was not expected.

First yes, you can store a fridge on its side but let it stand upright for
24 hours before attempting to run it. The guy below may have been lucky - It's possible for the comprewssor to be damaged trying to pump incompressible oil.

why would you wanna?
seems like more efficient use of space obediently standing up!
