We have had our Samsung SR-L3626B fridge for about about 6 years. It has
recently developed a strange fault whereby when it is powered on, the
fridge and freezer will cool and compressor & fan will run for a few
hours. After this, the fridge-freezer remains in standby but the
compressor does not start again. So eventually the fridge and freezer
compartments start to get warm.

Both the PSU and control PCBs have been replaced with new ones.

It just seems like a really odd fault which can only be rectified
temporarily by powering the fridge-freezer off and then on again.

I have tried invoking the test mode as per the service manual however,
the display does not indicate any fault codes?

Any help would be gratefully appreciated.

Thank you.

Fan... This is a "frost free" thing then? Spawn of the devil and
compared to your bog standard fridge/freezer highly unreliable.

As the PSU and controls borads have been replaced and it appears to
work in that the compressor/fan runs but doesn't restart one of the
sensors (note plural) may have packed up. The Thermistors used in
fridge/freezers do have a reputation of failing.

Searching ukwhitegoods.co.uk might already have the answer or ask in
the forums.

Dave, thanks for your reply.

I measured the resistance of the thermistor in the fridge and it is
within the range that the service manual specifies?

However, I will try substituting the thermistor with a fixed resistor.
