I have a hotpoint mistral FF92 fridge freezer. The temperature in both
the freezer and the fridge has been climbing and falling continuously
between -22 to -11 and +4 to +20 degrees respectively over the past
couple of days. Although today, the fridge is just sitting there at
+20.

I've cleared all the fluff that had collected on the condensor behind
the kick plate and tried it with both compartments 1/2 full and 3/4
full. It's been stood in it's current position for over a year.

It's making all the usual noises except there's no cold air coming
through the vent in the top right corner of the fridge.

Since we have a Mistral also, I kept a note of some previous posts
Ours is a 8596 with the LCD display, but I think they are all similar.

Check the evaporator thermistor;
(on the 8596, remove the fan cover in the freezer compartment and then
the back panel and the thermistor is cable tied to the evaporator coil).
It should read:

@room temp approx 3Kohms
@0 deg C approx 9K ohms
@-20 deg C approx 26K ohms.

There are two other thermistors, but this one is apparently the one that
usually fails.

Thanks for that Lee.

I've taken off the fan cover. The fan isn't turning and the two pipes
at the top left are frozen over. Also items at the top of the of the
freezer aren't frozen whereas those at the bottom are (guess this is
down to the fan).

Think I've identified the thermistor but how do I read it? Do I need
some sort device to measure resistance?
