The B symbol in the temp indicator came up on my 40 litre Engel fridge/freezer the other day so I changed the small round battery in the lid and put it back together and now the temp indicator stays on all the time. I must be getting old but I can't remember the temp being shown all the time. Checked the battery installation and it can only go in one way. Should the temp be displayed when the fridge is off??

Cheers Rod

Thanks for that, as I said I must be going senile because I couldn't remember it being on all the time.

Hi Rod

There are two types of batteries that power the LCD temperature display. The first series used the LR44 which would only last around the 12 month mark.

Engel then went for the lithium CR2032 which now lasts well in excess of 3 years....mine lasted nearly 5 years, and to answer your question, the temperature is displayed all the time.

The only exception to this was the introduction of the MR45FG Gold 50th Anniversary model. The temperature display on them is powered either through the either the 240v or 12v, depending what power you are using and the did play is in red and only on when the power is plugged into the fridge. There is now a new 40 litre combo fridge that uses this new power system.

Thanks Stephen mine has the 2302 and the battery has just seen it's 6th year without a change. I was positive that the temp went out when turned off but I must have been wrong

Old55,
My temp goes blank when the fridge is turned off too, so you're not going mad!
It's a 2009 engel (MT45F-G4-S) and has the CR2032 battery - sticker under the lid says expected life 2 years - mine's on the original too.

Stephen, there must have been a different variant around 2008/9

Cheers

Hi Phil

I have a 2006 model and like every new unit that we have in the shop, the temperature display is on 24/7 , except the new models.

I can not see why it is going off........faulty battery???

The running of the fridge has nothing to do with powering the temperature control unit, so very strange. I know that in time, all model Engels will be going over to the new powered temperature control.


Cheers

Curiosity got the better of me and we have an answer!
I just removed the CR2032 battery and it was reading 0.35V - very flat. Put a new one in (3.25V) and it is now reading the temp all the time!

So as the battery goes flat, it must somehow get a trickle of power from somewhere to keep the temp gauge going when the fridge is turned on.

Hi Trevor

The internal temperature display is designed to be on all the time ans i would suggest that you purchase a new battery, as it sounds like the same problem that Phil had above.

Well that's more and more confusing but mine did the same new battery and it is on all the time. Maybe there is hope for me too. Gee if I put a battery up my A..e would I stay on all the time too. Thanks for the replies Guys

It is only for the fridge that "B" means the B is buggered.
