Re: Not Cooling
It looks like the system tends to overheat. Maybe the condenser coils need cleaning or the condenser fan doesn’t run well. You shall make sure that the coils are clean and the fan runs at a constant speed without vibration.
Of course, if the condenser gets too hot, evaporator pressure and temperature increase so the unit can’t cool as efficiently. Also, in some cases, the varnish on the compressor electrical wirings doesn’t insulate them well causing small shorts, so there’s increased current consumption and the compressor overheats.
I have also seen some units getting their evaporator coil so full of ice and frost that air can’t even pass through. Even if the ice is cold, it acts as insulation around the coil so it can harm cooling capacity.
One quick way to know if there is a defrost problem is to unplug the unit and leave the door open for some time… if there’s lot of water in it or under it, it probably comes from the frost melting.
Depending on the model, the defrost cycle (at least for residential models) usually occurs every 6 to 14 hours of compressor run time.

In some cases, such as the washer thinking that water level went too high or took too long to fill, to stop filling and start the pump as a safety measure. In such case, you likely will get an error code too.
In case the washer thinks the water level is too high, you might have a clogged pressure hose. A quick way to check for this is to unplug the hose from the pressure sensor, if this stops the pump, then the hose or air trap likely needs cleaning.
It’s also possible that the drain pump relay on the PCB is stuck closed. Not very likely but it happens from time to time. This is likely the case is the pump starts as soon as you plug the unit even if it’s OFF.
Sometimes just knocking on the relay can help unstick it temporarily, but the problem will often come back again and again so you might be looking to replace the PCB.
Re: Fridge freezer not cooling?
It’s hard to give a specific answer without the brand and model of the appliance.
Please see below a few general possibilities.
– If the compressor runs for only a few seconds at a time, then stop, then restart minutes later while being warm/hot, it could be caused by a defective start relay. It could also be caused by a seized compressor.
– If the compressor continually runs, but the evaporator coil doesn’t get cold and the condenser coil doesn’t get hot, you might have a refrigerant leak, causing the appliance to be very inefficient. In such situation, it’s required to find and fix the leak, then adjust proper refrigerant charge… just adding refrigerant to the system won’t work for more than a few months at best.
A check valve into the compressor might also be defective, causing a leak from high pressure side of the system to low pressure side. This prevents the evaporator coil from getting cold enough and will also make the freezer too warm.
Basically, the only thing you might be able to fix yourself is the start relay. A refrigeration technician will be required for the other issues, and the cost can get quite high considering materials and labor.
