No idea if anyone can help but its normally a helpful forum

My home fridge/freezer is playing up, basically the fridge part is getting too cold and slowly freezing the food in there.

Have cleaned all ice out (which helped for about 2 days) and hoovered the rear heater element thingy (just)

Its only 3 years old and was VERY expensive!!

Any help?

Cheers

 

Thermostat gone?

.

 

turn it down

or as said stat might be playing up

 

STAT gone duff.
tabetha

 

its not a samsung american style is it??

mark

 

there wil be a temp sender in there soemwhere which has probably gone tits up

speaking of fridges, mines is making some funny noises, it's loud enought o keep the mrs awake at night and it sends vibrations through the house, i think it might be time to get a new one

 

just turn the knob down a bit

dojj
Hmm, my missus usually blames strange buzzing sounds coming from the bedroom on the fish tank filter

 

The setting is on lowest (i aint thick!!)

God know what to look for to fix it

 

when you say lowest, are you sure it isn't set to lowest temperature, i.e. the coldest?? I made that mistake with the fridge at work

 

LOL, maybe i am thick!?

It go's 1-5 and its on 1

It was fine for about 2 years then started playing up so should be set right anyway...

 

what make and model?

is it still in the same place in house?

possibly it has iced up inside if its a combi fridge (i.e. fridge freezer)
hard to do but if can fully defrost and turn off maybe enough to free it.

but as said stat could be playing up

 

the airduct to the frezzer compartment is that clear of food?? if not remove food from that section! cold air falls if its blocked it will just frezze that compartment and whats above!! secondly is the compressor constantly on as in always running?

 

change it to 4 and see how things go

i've got the samsung yank double fridge/freezer and, other than the aftermarket filters being crap, it's not issed a beat in nearly 2 years

 

Its a fridge/freezer, fridge part at top.

The make is Ariston so quite good.

Its the bottom half of top fridge that freezes, will have to try a full defrost but its FULL of food!!

 

Get a multimeter mate and check the voltage across the thermostat.

Also is the compressor running all the time? it would also
suggest that the stat has shorted out and will need replacing.

Just an idea from me and my supervisor who is teaching me all about
comercial refridgeration lol

 

he hasn't taught you how to spell it yet then?

 

Is the fridge freezer a 'frost free' type?

could also be not enough gas in the system(common fault

for freezing up in fridge)

 

has the compressor got nosier
or runs more might be on the way out or some of the refigerant has leaked if it has shearder vavle on it already get it regassed

 

if it has lost refrigerant it will work less efficiently and not get as cold

 

true but depending on the refridgeration system type a slightly under gases system will cause extended compressor running time hence the fridge will get too cold.also uneven frosting or ice build up on the backwall/evaporator is a indication of loss of gas.

mechanical thermostats either work or they dont,usually go open circuit,ive never had one go out of calibration

if the system runs on a pcb/thermistors set up you will have to get the resistence values from the manufacturer to test the thermistors

 

Its NOT a frost free, its NOT running all the time or even more often

No idea where thermostat is or what it looks like!!?

 

if its a non frost free model it should have a mechanical thermostat with capillary with either 2 or 3 terminals,im sure your thermostat is ok just check the end of the capillary is making good contact with the back plate/evaporator.

whats the model number of the fridge freezer?

thermostat is the knob with 1 to 5 on it,set to 1 and check it cycles on and off,if it does i would stick my neck out and say its a tiny amount undergases.probably requires a tiny squirt of r134a/r600.

always difficult to diagnose without looking at it

 

I'll get model number l8r matey, going to try a complete de-frost at some point

 

yes, a system low on refrigerant will be less efficient as i said, so the compressor will need to run longer to bring the temperature of the evaporator down. however, once it gets down to the point that the thermostat cuts it out, it will no longer run and so would not freeze up.

it can only ice up if the thermostat is set too low, the airflow is blocked, or the thermostat is no longer in the correct place. low refrigerant as a fault on it's own cannot cause icing
