Isotherm 12v fridge, issue when runs on battery

Taboy · April 2023

Fridge works great on 110v, but not on 12v. Even the light does not turn on. What should I look for?

There is a fuse for the Fridge in the converter. Check that, first.

Hi,

What is the voltage on your battery? The fridge requires 10.9V and will shutdown below 9.6V I'm not sure if the shutdown includes the light. But something to check?

@PTnomas: thanks. The fuse checked and is ok

@Yoshi_TAB. Thanks. The voltage is12.8V. So I should look for something else.

Hi, Another thing I may check is to confirm you have both 12V power coming into the WFCO (at the fuse) and the output side on the fuse. That will tell you which side of the circuit the issue is.

@Yoshi_TAB and @pthomas745. I found the problem. The breaker was tripped and I didn’t think to check it. Yours comments guided me there. Thanks and my trip from Myrtle Beach to Ohio will be more fun.

@Taboy..excellant. Certainly more fun when your favorite beverage is cold

..safe travels.
