Excessive frosting on fridge evaporator plate?

[Deleted member 36384]

The loop generates a trap to stop air being pulled into the fridge, cold air creates a slightly lower air pressure and it sucks in warm damp air from outside.

Thanks for the explanation.

It might work, although the temperature differential might be greater than you suppose.
The main thing your photo illustrates is that there's a lot of free air in that fridge...rather more than 75% of total volume, at a very rough guess. Filling it, as I suggested, would help.

Apologies for the omission from my earlier post, but beer is also an excellent packing agent

P.S. Defrosting (the wife's quick and highly effective method): empty fridge, wrap contents in a duvet. Place a large bowl of hot water at the bottom of the fridge. Wait. Mop up, re-load, switch back on.

P.P.S. Any damage to the door seal would, of course, exacerbate the frosting you describe, but I presume you've checked this.

Takes me ten minutes, switch off, open lid, put large tray under evaporator, open flap on evap, put nozzle of hair drier in to evap and within ten minutes the coating of ice peels off in to the tray.

We had a similar problem with our front opening Frigoboat. Unlike most domestic fridges the door seal does not have magnetic assist but relies solely upon a concertina type of seal being trapped between the door and carcass. When the door was locked mechanically I found that I could slide a shim all the way around the door. Obviously the seal had “relaxed”, probably through age hardening. Looking for a solution I came across some “P” strip. It’s normally used for sealing windows and doors in their frames and is widely available. By inserting the “P” strip into the folds of the existing door seal it padded out the seal sufficiently to ensure an effective seal. The result was dramatic! Instead of having to defrost the fridge once a week we now do it once a month in the Med summer and even less frequently in the winter months.
