Freezing Fridge
Hi Chaps
Not my usual area as normally stick to AC but i would appreciate your help with a friends problem.
The only info i have is its a fridge and keeps freezing up. They have already changed the stat and its still the same.
Sorry to be so vague but its all the info i have which was emailed to me from an old work colleage.
Any help would be greatly appreciated .
Kind regards
Gareth

Re: Freezing Fridge
Firstly: Has your friend fitted the correct sort of thermostat?
Secondly: Is it wired correctly? Some have a switch in series with the thermostat contacts.

Re: Freezing Fridge
To narrow this, you should first establish if compressor is running non-stop or it stops and starts by call from thermostat.

Re: Freezing Fridge
Ok , Have a little more info for you. I will check to see if the comp is running constantly although it is definatley running.
Fridge is a hotpoint RLA34G and it appears to be the plate covering the evap which is freezing up badly.
PS, its a fridge only ie no freezer compartment.
many thanks

Re: Freezing Fridge
Sounds more and more like the thermostat is the problem area.
Look at wiring.
Look to see if end of capillary is correctly sited so as to sense the evap temperature.
Whilst you are looking at the 'stat, make a note of its number...this can then give an idea of its type....standard or auto defrost.

Re: Freezing Fridge
as electrocoolman says check thermostat it should be standard danfoss type (part no 5045170963477) cant really mess up wiring as only 3 wires and earth.

Re: Freezing Fridge
Just an update,
The Compressor is indeed switching on and off via the stat.

Re: Freezing Fridge
Then check door seal for air tightness. After opening end closing, it should stick if you try to open it after few seconds! Or, check with paper that it not slips when doors are closed and paper is between housing and door seal.
Also check that liquid and moist food and drinks are covered with lids etc...
If fridge is combination fridge freezer with small freezer compartment check that it has all partitions and lids at place.

Re: Freezing Fridge
as already said, check the end of the stat is located in the correct place. and check its the correct stat fitted, ie, air temp or evap temp stat! the model number for the stat has been given in a previous post.
I would say it is one of the above if the whole evap is freezing.
If only part of the evap is freezing id say short of refrigerant.
But with out seeing the fridge............

Re: Freezing Fridge
Ok, i have some more precise information.
He has changed the stat to the correct danfoss one and made sure the capillary is sited on the evaporator exactly where the old one came off.
The Evap is still freezing up and the compressor never seems to switch off unless you switch the whole fridge off at the mains regardless of where the stat is set to 1 - 5.
Do you all think this pointing towards refrigerant?
I am assured the seals are good.
Thanks , Gareth
