Last night my fridge started making a very loud buzzing/ slight grinding noise. I switched off the fridge left it two minutes and switched it back on to find it was silent again so I left it overnight.
I came down this morning and the fridge appears to be warming up, the relay clicks in roughly every 5-10 minutes the compressor does a low hum for about 10 seconds and then the relay clicks off and everything goes silent.
I have tested resistance of the compressor and got a value of 38 between the bottom two pins and 18 ohms for the other two pairs. I know the values of two pairs should add up to the third but is this high resistance as I was lead to believe it would be between 4-10 ohms? There is infinite resistance between the three terminals to the compressor chassis and the starter relay gave me a resistance reading of 12 ohms which I think is about normal.
I discharged and tested the capacitor and that gives constant infinite resistance with no deflection and no continuity so I'm guessing that is definitely knackered?
