Shouldn't the stat be turned down not up? i.e. the lower the setting the colder the fridge? [genuine suggestion, not a piss-take] Quote Link to comment Share on other sites More sharing options...

[genuine suggestion, not a piss-take] The higher the number, the colder the fridge temperature. So, during the summer months when the fridge door is opened a lot and the outside temp is high, then the stat needs to be turned up to keep the fridge cold. In the winter when the ambient temp is lower, then the stat can be turned down. Saintly Fish, captin slows old outlaw and Geoff 3 Quote Link to comment Share on other sites More sharing options...

Is the ambient temperature too low for the compressor to turn on ? Looking at the manuals, yours needs the ambient temperature to be above 16c Quote Link to comment Share on other sites More sharing options...

On our domestic fridge the numbers are actually intuitive instead of being arse about face like Neil's fridge. Quote Link to comment Share on other sites More sharing options...
captin slows old outlaw Posted August 26, 2021 Share Posted August 26, 2021 get a fridge temp gage, it will not cost alot Quote Link to comment Share on other sites More sharing options...
Saintly Fish Posted August 26, 2021 Author Share Posted August 26, 2021 Well after a trip to Yarmouth today the fridge has decided to start working again!! Maybe I have a loose and dusty connection somewhere. Still, as long as it gets me through the next three days. Nothing like going away for 3 nights on the boat without a fridge to keep the beer cold! 😱 GPSguru 1 Quote Link to comment Share on other sites More sharing options...

Well it was certainly warmer than 16c yesterday! Not an issue now though, just a bit of a gremlin somewhere. If it gets me through the rest of September I’ll be happy. Then I can rip out and try to trace a fault. GPSguru 1 Quote Link to comment Share on other sites More sharing options...
Odyssey Posted August 31, 2021 Share Posted August 31, 2021 Sometimes the door switch can be sticky and it causes issues (same fridge) mine is ok after a bit of WD40 but may get replaced one day if funds allow…. Quote Link to comment Share on other sites More sharing options...
Saintly Fish Posted August 31, 2021 Author Share Posted August 31, 2021 Electrician has been down today to have a look. Seems my battery charger is fried. It’s only a 20amp one and I’ve added another house battery. So it seems like age and over work has killed it. Also seems like the alternator isn’t throwing enough charge to the batteries now either. So that needs to be removed and repaired!! Quote Link to comment Share on other sites More sharing options...

You mean the battery charger? Probably a rip off version. It has to be able to fit into the combined breaker/charger unit as the old one does.

I am guessing the rectifier pack has a couple of duff diodes in yours, so usually they replace both the rectifier pack and the regulator unit when they do a rebuild.

It’s the battery charger for shore power that is also needed. I guess maybe the battery charger never worked, and now that I’ve added an extra house battery the alternator struggled to keep up? I don’t know much about these things. GPSguru 1 Quote Link to comment Share on other sites More sharing options...

Possibly, but alternators don't last forever, I have had 2 on the Jeep. Also, the merc 150 that I have is known to suffer alternator failure within the 5 year warranty. If the shore charger has never been working, then the alternator will have worked hard continually charging partially flat batteries. I guess the shore charger is the same that is used in caravans and motorhomes. Quote Link to comment Share on other sites More sharing options...

Probably, but with the word marine at the front to justify the extra cost. Quote Link to comment Share on other sites More sharing options...
