    Fast shipping, poor instructions

    Got the package fast. The sensor was too long. Did not find any instrucions on how to replace it. On the web page I found a video of a zanussi fridge but it is not the same procedure. So please fix the length of the sensor and also update with correct instructions.

    Almost perfect.

    Would have given this a perfect score had the thermostat sensor wire not been twice as long as it needed to be. The space available for the coiled spare made it a very tight fit to get the housing back on, otherwise a very simple fit.

    Read the info. carefully!

    Prior to purchase, I understood that the stat. was intended for a 2 door fridge but reading other reviews, I was confident I could use it. The thermocouple was far too long so a 'coiling' job was called for but it didn't make for a tidy job. It worked, however, so it will do.

    If the freezer is working then it is unlikely to be the thermostat but meter the thermostat to confirm, if the thermostat is ok then it may be the refrigerant system.

Answer this question

I installed the part in my fridge but now I have gotten from +10 till -5 in the fridge. Tried both max and min on the thermostat but it is till the same. Anyone have any good answer to this?

    Check you have connected the wires correctly as there is one switch to the light and another to the compressor.

Answer this question

During the recent cold spell, my freezer wasn't completely freezing the items in it, and they started to soften, and there was hardly any frost on the coils. I moved the internal light switch in the fridge compartment so that the light remained on, i.e. there was warmth under the thermostat, and the compressor then switched on and off normally, and the freezer froze the items as it should, and frost built up on the coils. Is this an indication that the thermostat is defective ? If so, will this thermostat fit a Whirlpool ARC5553 / 850155515101 ?

    In your instruction book it will tell you that as this appliance only monitors fridge temperature that if in a cold environment the freezer may defrost as the fridge does not need to come on as often. It will also tell you that by turning on the internal light it will introduce a little warmth inside and turn the compressor on more often helping keep the freezer frozen. This fridge freezer like many should be in a warm kitchen not a cold utility or unheated area and is not faulty.

Whirpool model ART476/R. Thermostat is set at 1 [minimum] but ice rapidly builds up on the back wall of the fridge.

    This suggests either a loss of refrigerant or an insulation problem. This would require a systems engineer to re gas it.
