Another Hotpoint Mistral FF92 thread!

[JohnB]

For the third time in 9 years the temperature in the ‘fridge has risen to over 20oC. The freezer looks ok at -22oC. Previously I’ve replaced both thermistors with new ones “just in case.” This time I’ve just replaced the evaporator thermistor, but the problem remains. I’ve also noticed that the fan now appears to be working only intermittently.

My queries are:
a). Would replacing the freezer thermistor have any chance of solving the problem?
b) I believe that the fan extracts cold air from the freezer and circulates it in to the ‘fridge. As it only works intermittently what actually controls its operation? Surely the ‘fridge thermistor?
c). Is the fault likely to be more serious, e.g. the PCB?

Thanks for any help that you are able to provide!

Re: Another Hotpoint Mistral FF92 thread!

I’ve been researching the Mistral threads and the following quotation is taken from one in 2008:

There are three with this model, plugs are colour coded, yellow, green and white. Yellow and green are in the freezer compartment and white is in fridge area.

I’ve always replaced the yellow and green thermistors but I can’t locate the white one in the ‘fridge. Any ideas? Perhaps my model is of the older variety, as it was bought in 2001?

Re: Another Hotpoint Mistral FF92 thread!

Spent a number of hours on this problem! The result is that the freezer temp. is still at -22oC; the fan now seems to be working perfectly and all the crud/fluff has been removed using my trusty Dyson…………….but the ‘fridge temp. remains stubbornly unchanged at +20oC! So just what is, or is not, happening? Does anyone have a clue?
