Battery Issue

[Mike J.E.W]

On a week long trip last week small red light started flashing on the fridge ,is this the sign the battery's are needing replacing or is there something I should be checking 1st

Guessing you have no other indicator. In the absence of that it is usually one of three things, IMHO:-

 

Battery issue

Alternator issue

Connection to/at fridge issue

Resolution is to have the items tested starting with most likely. Do not presume batteries are kaput investigate, much cheaper than replacing

[Phil Ambrose]

I would guess the dashing red light would indicate that the battery voltage is too low . Now some questions, what size is your battery bank, what is your charging regime, how do you monitor your battery bank and what else is drawing power from your battery bank.

If you have failed to charge sufficiently this may be your problem and the fact that the under voltage light is flashing does not necessarily mean you need to start replacing batteries, you should do a power audit to ascertain how much you are using. Come back wth a bit more info please.

Also how many flashes in each group? Fridges normally flash a fault code so just saying "flashes" means there is some kind of fault in the areas already listed or with the fridge.

Absolutely As above,

Might even be a temperature issue, say if the sun has been shining on the door, and fridge can't get down to set temperature.

If it's a Shoreline fridge, a single flash every 4-5 seconds is a low voltage warning, and it switches itself off.

 

We've had this a few times first thing in the morning.

 

Here's the tech manual if it's any use.

First checks would be battery SOC, it may be 'flat' through lack of charging or over use.

 

Then all connections between fridge and batteries, they may be loose,dirty or both.

 

Check voltage at fridge compared to that at the battery terminals, hopefully it is the same or as near as.

 

After that it gets 'technical'.
