An actual brewing related rambling/PSA
One of my three relic Craig's List fridges had been acting a bit wonky lately. It's the oldest of the three top-freezer units in my humble brew space that range between 17 and 22 cf, and has been Chamber 1 for over a decade now. As I'm just about to get brewing again after taking the heat-stroke-inducing summer season off, this would be bad timing to lose any of my fermentation chambers, and especially as I expect to kick things off with back-to-back brew days.
So I got on to Craig's List (as always) this Monday and immediately came across a nearly new GE 18cf top-freezer unit that would fit the bill with sufficient floor area to fit a pair of 6.5 gallon carboys for fermentation, and sufficient vertical space to fit cornelius style kegs with ball lock connectors when needed for conditioning or cold storage. The seller was amenable to me coming over Sunday (today) and I let them know I'd confirm the visit the day before (now yesterday).
Yesterday I got on the GE appliance site and downloaded the user guide for the unit being sold. In about a minute I realized the unit uses the exterior skin on both sides and the back as a radiator for the condenser loop bonded to the inside surface. Basically the entire exterior is sheathed in uber thin sheet metal with tubing underneath.
Obviously that would make drilling holes very risky - and I need to drill holes for two power lines to an always-on interior fan and to a switched heater, a bus line to the ds18b20 sensors for cabinet and beer temperatures, a CO2 line coming in for cold-crash O2 avoidance and for keg carbonation, and a gas line going out for purging kegs using fermentation gases. Ie: lots of holes = lots of opportunities to murder the fridge by puncturing the condenser loop.
I would have liked to have replaced a relic with a nearly new unit, but I let the seller know why I had to pass.
This design style seems to be gaining market share so folks need to be aware of the ramifications...
Cheers!
