We've a servis fridge model M7611.
contents were getting too cold at a low setting (1), switched it off overnight to defrost.
Now it wont cool at all even at max setting (5)
Hiya,
At the bottom rear is the compressor.
Is this running?
If it is, is it very hot?

Thanks

yes, it's runnning and very hot

Hiya,
This suggests a system blockage.
Unplug the machine.
Put a fan heater at the rear to heat up the pipe work, especially the very thin coiled tube.
Leave it like this for a couple of hors.
Then, plug in and see if it runs again.

Let me know what happens.

Thanks

Fridge now unplugged.


There is no thin coiled tube, it's just a short length of uncoiled copper tubing on left of attached picture....presume that's what should be heated. Will try leaving unplugged and heating as suggestedM7611 fridge

Hiya,
Yes, the thin tube attached to the bulged part is the likely place it's blocked.

Thanks

I've now noticed the thin coiled tube, tightly wrapped around input tube to compressor.


 


it was obscured by a covering of chewing-gum like material.


I've removed some of this material in order to get some heat into the coil with a hair-dryer.


 


Switched back on now....fingers-crossed...should the coil go cold ?


 

Hiya,
Normally it would get cold just after the bulged part.

If you are lucky, the compressor will be running and not just humming and clicking off.
The compressor should be warm, not hot.

Let me know what happens.
Thanks

Compressor not clicking off at all, permanently on and very hot.


It's only when I switch off/on it takes a while (3-5 mins) for compressor to start, then it stays on.


Bulged copper bit and coil cools but inside fridge still doesn't.


Lots of high pitched chirping and gurgling coming from much higher at back of fridge.


seems to come from behind the insulation.


Any suggestions ?

Hiya,
OK, sorry, you have a restriction that's causing the heat in the compressor, it's not blocked, hence the reason you hear the gurgling.

I'm afraid it's not a diy job, you need a refrigeration engineer to attach gauges and a vacuum pump to the compressor pipework to determine if the restriction can be cleared.

At worst, you'll need a compressor and regas costing around £200.
At best, you'll need a regas costing around £130 .

It all depends on whether it can be cleared or not.

Sorry it's not good news or a simple fix.
.
Good luck with it, if you decide to go for repair.
(Personally, I'd be using the potential repair costs to replace the machine, Servis went bust in 2008).

Hope this helps
Thanks

Thanks for the advice...we're looking to replace now.


Finding one of same dimensions to fit in existing space is the difficult bit.


 


Not that it bothers me but there'll also be a mismatch with the matching Servis freezer we have.


 


Will need to replace both "because it won't look right" I'm told.


Need to go shopping then


 


Cheers.... Andy

Hiya,
Good luck with the search for replacements.

If you haven't already done so, I'd appreciate it if you could rate the help and answer you received, it's how I'm paid for my time and efforts.

Hope this helped
Thanks
