    Why wait?



    Over the years i've heard people say, they brought home a new fridge or shop owner purchased a 2 door display and left it stand ? hours before turning it on. SO i ask, why wait? No-one Knows, they heard about it from someone else. Maybe its something to do with gas electric ammonia absorption, or is this a old wifes tale?

    Its from a time when the shop that sold electrical appliances knew about the product that they were selling. Or had someone in the back of the shop that knew about them.

    They used to tell you as a precaution not to switch it on for a couple of hours, then it turned into twelve hours due to "fishermans tales." And the lack of technical knowledge from todays till operators that work in the shops that sell them.

    If the fridge has been laid flat in the back of a car or van, theres a slim chance that the liquid can enter the evaporator from the condensor and cause the pot to slug the liquid. So they advised it as a precaution.

    Hi Mike
    This is not an old wives tale. Sometimes when a fridge is transported like on a trailer... The oil can travel down the pipes and cause a hydraulic block. So it's a good idea to wait for an hour or two to let the oil drain back into the compressor. This is not confined to domestics I had a CRAC unit that was trucked on it's side and when the boys switched it on it went out on the HP switch. I ended up having to take some gas out and then put it back in again. The moral of the story should be not to transport fridges on their sides.

    I agree with Tesla's thoughts. Standing after movement to let everything diffuse around the circuit, can't be a bad thing.

    The worst that can happened is that the oil will flow up the suction tube.
    I have never seen anything happening to a fridge from transporting it on the side but as a precaution, I would suggest the it will be left to stand upright for an hour or so just to let oil that flew up suction line, return to the sump.

    I've had it once with a fridge we transported. stood it up for 1/2 and turned it on - comp went out on it's klixon

    we tilted it the 'other way' for 10 minutes.Swiiched it on and it ran up no problem

    If transported on it's side just make sure the pipes are pointing up that's all..

    So there is some truth to this, however it seems strange that above items might be transported on their side?. Should this be the case then it does make sense. Thanks.. Mike.
