    Default Time switch on refridgerator

    Hello,
    My 24v refridgerator has started icing the coldplate on the rear of the interior after 3 or 4 days. A refridgerator engineer has had a look and cannot see why. I suggested fitting a time switch in the main supply line that would turn it off for 30 to 60 minutes every 12 hours when supplied with power. The engineer said that is a reasonable solution as there is a drain pipe in the refridgerator. However, there is a huge selection of 24v timer switches on e bay and their (chinese) translated instructions are, er, all chinese to me. No doubt, if I had a suitable one in my hands it would all make sense, but which one? This might be OK-

    I would solve the problem.

    Fridges tend to ice when they are not closed properly. They run and run and moist air gets in

    The engineer found nothing wrong, so if there is something, its going to be very difficult to find. the door seals are good and run time reasonable.. There does not seem to be a defrost system.

    Be aware low refrigerant charge can cause premature icing. Can you see on the evaporator plate where the ice stops, or after a defrost where the sweating on the plate stops. It should sweat right up to just before the outlet pipe back to the compressor.

    Could also be a poor door seal letting moisture laden air in.

    Generally the fridge will be above 0oC, so if you fit a temperature controller close to the plate it could turn the fridge off when the ice layer builds up onto the probe, but this may not be a proper cure for your problem.

    Something like this ...

    We have one of the second type you illustrate. Has been working running our garden pond pump, off a 12v battery and solar panel, for the last 3 years - has more feature than you need ,but at the price it is good for the job.

    Hello Gwylan,
    That sounds like the one for me. Do you know, if you cut the power to the timer and then power it up again later without pressing any buttons, whether it remembers the previous setting and then carries on as before, please? This is because I wish to install it under a switch panel which is screwed down. I am not worried about the date.
