I normally keep it around 77 what tipped me off was the digital display of 63 and I did a double take and checked the thermometer in the tank and it was 65. So I verified the chiller was set for 75 and it was so I unplugged it then after about 10 sec plugged it back in thinking this would reset it. It flashed fire and had a sizzle sound with smoke. I unplugged it ASAP
. I had the unit now for about 4 years with on and off use. I just had it apart to blow the dust off and very thing seem to be working ok it was cycling on and off. I could have been a controller problem and then the motor overheated and drew too much current after I plugged it back in. RedSea do not even list a chiller on it website so…I’ve e-mail them today, no part support in the paper copy of the manual… it did not come with one..?!? I had to contact Redsea to get one..
