Whirlpool ARC7410 – Help Please!

[Hagdogg4]

Hello everyone,

I’ve had the Whirlpool ARC7410 now for two years, although my mother in law had it for a year beforehand and I’ve had no problems with it so far but now the fridge will reach its desired temperature and then switches off, like it is supposed to do. After this my fridge will not come back on (after becoming warmer inside off course) until I turn the fridge settings dial to OFF, wait 5 seconds and then back to the desired setting. After this she will come on again.
On older fridges this would be the thermostat that needs replacing, but on these fridges there is no thermostat as such. I had a company come out and they took apart the freezer and found that the radiator and fan were completely frosted over. They cleared all the ice which briefly fixed the whole thing, however, the problem returned so I took apart the freezer and did the same – it only provides a fix for a week, two at the most so isn’t practical.

The dial inside for setting the desired temp is just a potentiometer and then there is a ‘SPACE 4’ sensor thing on the inside of the fridge, don’t know what that is doing though? As far as I know then there is a BI-Metal strip on the back of the fridge as well?

Any thoughts on what could be the problem or which part I should start to change out first – or if I should just get a new fridge would be greaty appreciated.
