UGH! - last night, I noticed the LCD's were out on my temp controllers. Hmm, tripped breaker? Opened fridge door, and light is on. The circuit I had powering the controllers is dead (which also fed the compressor start/stop). No problem, I'll rewire it to use the light's 120V circuit. Not using the freezer light, so load should be OK. Compressor comes on (after 10min delay), everything seems back to normal.
This morning, freezer with 1 keg in it, is at 55°C (133°F) and ferm chamber, with 1 carboy, a secondary in it, is at 45°C (113°F).
Maybe I bypassed a safety to the compressor by using a different power source to run it? Where do I start with this? I know controls, but not small refrigeration circuits (no wiring diagram on this guy).
