First time was a faulty temp probe.
Now I'm not sure what the issue is. Came home Saturday to no power to the tank and 3 dead fish due to a tripped circuit breaker. Tore everything apart, nothing looks frayed or rusted. Isolated the problem to the DC8 turning my lights on. When I plug them into a regular socket, I can turn them off and on without a problem and can unplug it while on and plug it back in. But when plugged into the DC8, it trips the GFI or circuit breaker or both when I try to turn it on through the ACjr. If I leave the socket on, but turn it off at the fixture, it's fine. It's only when I use the controller to turn it on.
so fixed that problem and then found that the temp is messed up, but not with the probe this time. The program says turn the heaters off at 80.5 and turn them on at 79.5. Woke up Sunday and the temp was 82. Checked the probe against a lab thermometer I have and the temp was correct. But the heaters were still hot. After the first (of 3) temp probes I had failed, I set the heaters to 82 so that the ACjr couldn't cook the tank again. Now for some reason the ACJr. won't turn them off. So I manually turned the socket off through the controller...and the heaters stayed hot an hour later! I even tested it with a powerhead. The controller says the socket is off, but it still has power.
Any thoughts on what to do besides take this damn thing out back and shoot it? So many failure points I have no idea how to be comfortable with this thing.
