Re: stopped cooling -fisher and paykel fridge
Ok you say the compressor sounds right?? there's probably a defective relay overload / start cap combination defective. if you go behind the the fridge and remove a small cover you will see the compressor with power disconnected look for frayed or burnt wires take the compressor cover off and you will see the wires just follow the 3 wires. you can buy a replacement relay/overload capacitor combination all you have to do is wire it any additional questions you can e-mail me at firstname.lastname@example.org

The system is either blocked or you have a gas leak but i would expect it is blocked and the only way to find out is to get a refrigeration engineer to check it for you, but explain the problem to him first and make sure he can help before you spend money.
This kind of noises produced gas in cooling system.
In the old coolers never heard sounds like streaming water because the compressors were very loud due to high pressures (12 bars or more), which were required for efficient cooling. Today we use more ecological gases which work (from 5 to 6 bars) at much lower pressures, thus compressors produce much less noises and now suddenly we hear sounds that never before heard. Generally speaking noises is lower, measured in decibels.
pull the unit from the wall, remove the bottom back panel , see if the small fan is working ,if the fan is , there's probally alot of dust back there,unplug the fridg. and vacuum the area real good,use a flash light to make sure you get it all, if the fan is not working and the compressor is running the fan is the problem ,the fan keeps the compressor and coils cool so the freon can cool down so the unit works like it should,if the freon is hot ,the air the fridg.will be blowing will be hot. this should fix your problem, and YES its worth fixing.alittle p.m.saves alot of $$$$$$$$$
Is the compressor (the football-sized case on the outside back of the refrigerator) making a continuous hum or other noise? A constant noise could indicate a serious problem with one or more components. This is a repair that should be left to a refrigerator service expert.
If you hear a clicking noise every few minutes, this means your condenser is trying to work but can't. If your condenser coils are clean, the problem could be the start relay, which triggers the compressor. Have a refrigerator repair pro determine if the start relay is the culprit and to replace it if necessary.
the motor of the compressor may have tripped on overload protection. Allow it to cool down and then unplug the fridge then plug it back in and try to run it. It should run. Be advised that the condenser coils underneath need to be clean. You should have a strong person tilt the empty fridge while you vacuum and clean all the dust and lint off the coils. Be gentle as these coils are fragile and are easily damaged. Hope this helps.
AS A FRIDGE ENGINEER I HAVE COME ACROSS THIS PROBLEM BEFORE IT COULD BE A LOSS OF REFRIGERANT ALTHOUGH THIS WOULD STEADILY WORSEN IN USE,MORE LIKELY THERE IS A BLOCKAGE IN THE SYSTEM STOPPING THE REFRIGERANT REACHING ALL THE PIPEWORK THE CHEAPER FREEZERS USE THE SHELFS AS PART OF THE FREEZING SYSTEM.
THE ONLY SOLUTION IS A COMPRESSOR CHANGE AND REGAS (COSTLY IF NOT COVERED BY WARRANTY/GUARANTEE ETC)
IF FREEZER IS MORE THAN 5 YRS OLD BEST TO SCRAP IT UNFORTUNATELY..
Remove the panel covering the compressor. Remove the relay plugged on the side of the compressor and shake it. If it rattles or has any burned spots it is shorted out. Try replacing it first. Make sure you replace it with the correct replacement, not a fit-all. If this is not the problem you will need to replace the compressor. If it is less than 5 yrs old the compressor should still be in warranty. If so call Sears, it will be repaired free of charge. If it is out of warranty buy a new freezer.
We had a Kenmore upright which worked fine but then suddenly was not keeping food frozen. Long story short, do not store anything on top of the freezer unit. It will insulate the coils that run across the top of the unit, and cause your compressor to work harder than it needs to, and eventually overheat and become ineffective. Says nothing about it in the user manual. We learned the hard way by losing food.
