Are you saying that it's a non working fridge? Sounds OK it fits two fermenters. Makes up for all the downsides of using a dead fridge. If it didn't then non working fridges are not so great. Better than a cardboard box of course, but I wouldn't go out of my way to get one - maybe if neighbours were chucking one out and I'd only need to travel 20m with a fridge trolley.
Normally with old fridges the seals and insulation is shot, wasted ugly space with a dead useless freezer, have to maybe make up a bottom support to hold the fermenter over the compressor hump (wouldn't trust the vege drawers). Of course due to piping the inside heats up when the outside compressor and piping heats up in ambient, metal cabinet, drain is open too, lose cold air when opening up. Stuck with something to get rid off when moving house (matters to me because I'm a dirty poor renter that lives in cheap cheap houses destined to be knocked down.
An insulated box made from foam or plastic with good insulation would be smaller, more efficient , better use of space etc than an old dead fridge that only fits one fermenter.
Of course, disregard if it does work in cooling mode.
I can't use a fridge because I'm already uses 2 fridges for food and storage and drinks. No where to put a 3rd here and don't want to pay a few hundred extra per year to run another one.
e: Also if the OP is using I assume brigalow yeast, that's usually OK at 24C. I did some early this year and compared to coopers yeast (which is horrible at 22c+), the brigalow stuff doesn't have a strong bad flavour at slightly warmer temps.
