Top 5 common issues problems faults refrigeration fridge freezer

In the video below i show the Top 5 common issues problems faults refrigeration fridge freezers i come across in my daily repairs.

These issues are 

Capacitor , these help start the motor in compressor if they are faulty the compressor will not start and usually hums, you nned to test this with multimeter, set multimeter to capacitance and measure if its 10% out of the capacitors stated range repalce it.

Relay and thermal cut out device are all built into one and are a regular problem of faulty fridges.

Compressors can fail both mechanically in which case usually you can hear the problem or electrically in which case you ned to test resistance of motor windings.

Regassing is a major iswsue i find eventually gas will leak from mirco crack in joints and eventually this will affect refrigeration cycle you need manifold gauges to test and regass.

Thermostat , these go often and need replacing if its already been replaced check it fits ok as most often people by cheap replacements and they are the incorrect length the phial then take incorrect readings and is virtually useless.
