Need some help above intergrated freezer compresser stopped working getting ohms reading from all terminal 3 and 6 ohms not shorted to ground cap 2.5 + – 5{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} reading 2.3 ptc relay casing burn marks but getting reading 34 ohms across terminals Green light lit at front and when you press button yellow light lit any one with experience of this freezer fault thanks fasetester

Assuming that the overheat klixon is okay then I would put a amp clamp on the power (ideally just on the feed to the compressor but on the mains input if not) and see what it draws, if you see more than a couple of amps flow for several seconds at a time when you know that the compressor is supposed to be running then it would indicate a seized compressor – it may well draw a high current for 5 or 10 seconds before the klixon cuts out and then take 30 seconds to a minute (maybe more) before it trys again.

Thanks jem for your reply there no sound from the compresser if it was locked would it not hum and the klexon cut in and out was thinking might be no power coming back to the compresser to power it is there any stat inside the cabnet fasetester

I would expect to hear the klixon at least but have come accross a couple of extremly quiet locked compressors so would not guarentee to hear it hum – they will often be hotter than normal to touch.
I don’t know what the control system is on that model and would need the 9 digit model code to look it up but if it is a mechanical thermostat then you can ohms test between the line pin on the plug and the common on the compressor to see if it is working.
If your tester has got some crocodile clips for the test leads then I would try connecting them to the neutral and common on the compressor and then turn the fridgeon to see if you have voltage to it or not.

Thanks gem for your reply it controlled from a pcb on front panel power comes info pct goes to front pcb through it back to compressor and condenser fan should the fan not be running along with compressor the only other component is a ntc to monotor tempture it would not stop fan or compressor from working would you agree

[Hollytree_Technical]

I would expcet the condenser fan to be wired in parallel with the compressor so if neither is working then the PCB is not sending the power back to tell it to work.
Does the PCB have a large rectangular capacitor on it? If so then it would be worth checking it and changing it if it is more than 20{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} off of its marked value, it is quite possible that it has enough power to run the processor and lights but not the relay.

The only way that the NTC would be likley to stop the compressor is if the module thought that it was already at temperature, if there is an alarm light showing then it is probably reading the temperature okay.
