Hoover HNMF 2805a Fridge Freezer Defrosted

[RBZ5416]

Had an issue with the freezer section completely defrosting a couple of days ago, to the point where everything inside was completely thawed. The fridge was unaffected. Oddly, it then refroze with no input from me & has remained frozen.

Can anyone suggest why this might have been? I think it has a single compressor so possibly a fault with the frost free? Now have to try to work out whether it's likely to happen again. Could probably do with replacing given its age, but it's a narrow circa 54cm & might be difficult to replace given nothing wider will fit.

Thermostat fault although a complete guess.
Not much to fridges. Thermostat. Pump. Controller.
Sometimes it's cheap and easy to swap so decide if it's worth a punt

There are independent controls on some fridge/freezers even with a single motor, I have noted the defrost cycle on mine seems to have a variable time, but I am sure there is an alarm if the temperature goes too high, I know with a power cut, on power returning it shows highest temperature reached until the door is opened when it is reset.

I can't get the manual for your model, however with my own Hoover I found the ice could jam the fan, and around once a year had to switch off and empty it, and prop open doors, and aim a fan at the freezer to melt the ice built up behind the shield. Once this was done got another year without a problem, but since behind the shield, had to wait until floor of freezer was dry to be sure all melted behind the shield.
