Hi all, Just wondering if anyone knows how to recalibrate the voltage reading on a Liemack fridge, voltage display is reading 13.4v actual voltage at the batteries is 12.4v. ( I have searched the archives without lany uck)

I had this problem years ago when Liemack were still operating and was told how to do it by their tech. I think I had to hold down 2 buttons at once and then I could alter the reading with the up and down buttons.

I have tried a few different combinations but can't get it to do it, any help greatly appreciated.

Thanks Neil.

Failing a successful response form Member No1 's reasonable suggestion you could contact Rod Dun on 0418423610 he was the NSW distributor for them and stilll uses and swears by them.

Rod is travelling at the moment but I caught him with reception near Gosford.

Press the battery Button and it tells you the cut out voltage.
Hold the battery button for three seconds and it locks in and then use the up or down button to adjust the cut out voltage to what you want.

Ihope this helps.

Thanks for the info, I spoke with Rod Dunn this morning and he has never had to recalibrate the voltage meter, and was not sure how to do it. As my voltage meter is out by 1 volt I have just adjusted the cut out by 1 volt which will keep the unit operating correctly ( so I can start the car???) until I can sort it out.

We are going bush for a week, I will keep trying.

Thanks again

Neil.

Neil,
Are you aware what has caused your 'Voltage display' to change yet again ?

Hi Mainey,
I am not sure, I have had the fridge since early 2000 and this is only the second time it has happened I think both times it has been by 1 volt, maybe it has a Y2K bug????

If it starts to cause a problem I will have to look into it further.

regards Neil.

1. Access power supply leads with voltmeter, check voltage, check voltage on fridge by pressing BAT button
If not matching adjust as indicated below

2. Press the BAT button at the same time as connecting 12 v supply
"SEt" will appear followed by voltage reading
Will not have decimal point ie 122 = 12.2
Use raise and lower buttons to adjust to voltmeter reading
disconnect power

3. Perform step 1. again

Cheers
JR

Thanks JR,

I have followed your instructions and now have it reading the correct voltage. It's easy when you know how. I have written the instructions in the fridge info book in case it happens again.

Thanks heaps,

Regards Neil.
