Re: frezzer cold only
Hi bcullen
when switched on does the two pieces of tube coming from the compressor change temperature
as in one gets hotter and the other colder - would be handy if you had a temperature probe
and could monitor temp change or none

Re: frezzer cold only
Thanks for reply:
Just turned on, yeah one pipe is getting warmer the other cooler. I do have a lazer thermo thingy so

Re: frezzer cold only
Hi bcullen
infra red are not accurate but will assist in working out if your refrigerating or not
with one getting hotter and other colder it appears you are to some extent
if you can start the unit and take the temps on both pipes after a few minutes (3) and then again after 20 minutes
then post them
this will give us a vague idea what is going on
Reading back through your post, I am suspecting already you have a blockage

Re: frezzer cold only
Hi Mr Chillerman
15.8 was the temp at startup of both pipes after 10min compressor was 55 one pipe=25 the other=35
after another 20min compressor was 65 one pipe= 35 the other =45 all seemed to increment at approx+10%
hope this helps

Re: frezzer cold only
Really hate to burst the bubble but second hand fridges and freezers carry a very high risk of failure. Did you see the freezer working and freezing before you bought it? Warm compressor and quietly running with little or no cooling inside can only be one of two things, blockage though not likely, and evaporator, or inside cooling pipes have sprung a leak.
To the optimist, the glass is half full. To the pessimist, the glass is half empty.

Re: frezzer cold only
The leak sounds terminal? what does the evaporator do? Would a fush and regas achieve anything

Re: frezzer cold only
Hi bcullen
by your temps, it appears you either have cap tube blockage or have lost refrigerant
your lower temp pipe should have gone down in temp not up
but you have so little cooling, your compressor heat is being transfered to this pipe
the cap tube is the metering device that goes to the cooling coil (evaporator)
it can be fixed, either leak found and repaired or cap tube blown out with nitrogen or replaced
then regassed, but work will probaly exceed the cost of the freezer, unfortunatly

Re: frezzer cold only
Try another appraoch, your fridge run on R-134a which many times blocks the little filter right after the condenser.
You need to replace the refrigerant and the filter\drier.
I have seen this problem many times and this action eliminates it for good. use a dubble volume drier.

Re: frezzer cold only
hi Thanks one and all it looks like refrigerant and the capillary/drier are the problem so i will find out how much a fridgy will charge me

Re: frezzer cold only
Depends where you are in Australia. Did you see this freezer working before you bought it?.. Mike.
