Symptoms are: compressor starts and gets hot, turns off after a few seconds with an audible click. Starts again after some minutes. Repeat. Temp dropped from 18 c to 8c after 4 hrs but no lower. I changed the run capacitor (because it was easy to get and change, worth a try), but no difference. Could it be the ptc resistor? Or the compressor has had it? Built-in freezer is approx 8yrs old. £600 for new one vs repairs. I’m a heating engineer, relatively handy but not worked on freezer before… any suggestions or tips appreciated.
Could it be that there isn’t enough refrigerant or there’s a leak causing the compressor to overheat, making the PTC cut off the power? Are both the thin and thick tubes hot?
Thanks for the reply Jack. I was hoping for a bit of diagnostic help to figure out what was wrong, but recommendation was freezer is knackered, get a new one. Still no idea what was wrong but got a new one! Thanks for the interest though.
It sounds like the compressor is struggling to start properly – the repeated clicking usually means the start relay or PTC thermistor is falling, not necessarily the compressor itself. Since you’ve already swapped the capacitor, try replacing the PTC starter/relay. If that doesn’t help, the compressor may be weak or partially seized. Given the age, weigh repair cost vs. replacement, but start with the relay first.
