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.
