Re: Chest Freezer – stays at -30 deg C

Just for the record I reconnected the leads that go to the thermostat as follows: To make sense of this you will need to read the following in conjunction with my last post about the connections that was posted at 11.44 today.

The two brown Cables that were on spade connection 4 are now on spade connector 3 and the two black cables which were on spade connection 3 are now on thermostat spade connector 4 leaving the single black cable on spade connector 6 on the thermostat’ However, the result is that the red higher than set temperature warning light remains continually ‘ON’. With the thermostat set at nearly max and the compressor is continually running the max temperature measured inside the cabinet is now only
-15C previously it was off scale beyond -30C. I will see what has happend in the morning. Can’t think what is wrong so it looks like a new freezer!!

How do I direct my question to R600a (Bryan)?

Re: Chest Freezer – stays at -30 deg C

I still have a problem – Help
The new Ranco VS5 thermostat is now regulating the temperature inside the freezer. Also the fast freeze button also works by bypassing the thermostat setting. That’s the good news. However the red warning light for “temperature higher than set” light is on continuously.

The VS5 has 3 male spade connectors numbered 3, 4 & 6(this one also has a number 2 which is not shown in the Ranco circuit drawing?) ignoring the earth connectors of which there are 2.

I have traced the wiring from mains plug to the system and have the following:
The mains cable is 3 core where the brown cable goes to the compressor connection. This connection has two electrically linked spades. One cable, brown, goes to the user light inside the freezer cabinet, the other, brown, is part of a 4 core cable that goes to the spade connector on the thermostat which I have on connection 4. From that spade on 4 a brown cable is linked to one side of the ‘fast freeze button/light. From this fast freeze button/light it links on by a brown cable to the ‘Power on’ light.
The other spade, marked 2/6 on the thermostat has 2 black cables, one of which goes to the ‘Fast freeze button/light. The other black cable from the 4-core cable goes back to the compressor.
Now the other thermostat spade connector 3 has a single black cable, which goes to the red temperature warning light, which remains ‘on’ no matter where the thermostat control is set?
Any ideas how I can reconfigure the wiring to get the red light to only come on when the setting, set is not being maintained.

Thanks kwatt,
Will do as you suggest. Had to go out this evening so fitted it rapidly before I left. It’s all hanging outside the cabinet. the fast freeze seems to be working but not too sure till tomorrow whether it is working as it should. Will let you know as the red light is on. even if I turn the stat to min. The temp has risen inside to -20 from -30C.

Re: Chest Freezer – stays at -30 deg C

HELP 🙁 😕 ❓ 😥
Have just received my replacement Thermostat (VS5 – Universal Freezer Thermostat) but find the capilary phile is twice as long as the original one. Is it ok to coil up the excess length leaving it in the ambient external temperature or should I try to carefully bend it not too tight of course and feed a double lenght into the insert tube making sure I don’t kink it and that the tip is at the furtherest point into the cold area? assuming it will go.

😀 Thanks kwatt,
Will probably order what you suggested as you are the first to give me a clear suggestion. I find it odd that I can’t just get a Danfoss direct replacement, but ha ho such as it is.

Re: Chest Freezer – stays at -30 deg C

Thanks kwatt ,
Not sure what the DAD’s is about?
Are you saying I should preferably get the replacement from Gillman’s or would the one you suggested be as good?

If your fears are correct I assume it’s a new freezer?

🙂 Thanks kwatt ,

The freezer was bought in March 2002 from Gillmans in Gloucester.
What other problems might there be and what checks could I do to locate the problems?

If I don’t get any more info then it may be worth trying the one you suggest?

Re: Chest Freezer – stays at -30 deg C

Thanks johnmac11 & cockney steve,
johnmac11 thanks for the web site,that is my freezer in their list but they don’t sell spares from what I can see. I am happy to install my own thermostat if I can get the correct replacement. I have used the Email facilities in a number of other sites most don’t respond of the others they say they haven’t a replacement.

All I want is to know the details of alternative thermostats and where I might get one.
Thanks

Jimlad :rolls:

Re: Chest Freezer – stays at -30 deg C

Yes cockney steve, but it doesn’t list thermostats for my Freezer or recognise the info I gave for my thermostat as fitted. So I am stuck unless I am able to determine a replacement. 🙁

Re: Chest Freezer – stays at -30 deg C

Thanks cockney steve,
I had seen the belows which is joined to the capilary tube and assumed that was the actuating method. What I now need is to obtain the correct replacement thermostat if you or someone can advise me on which one. Most spares sites don’t list the King Freezers.
I don’t think it’s worth playing with the adjustment screw as it is probably NBG.
The other problem in picking the right replacement is that some thermostates have live feedback?? My freezer hasn’t got a defrost system. It is done by turning off the power, nice & simple.

So hope someone out there is able to tell me which one to fit to replace it.
