I have a Rthb150 that tripps on current overload only at night on ice making start up. Cts/Compressor mod, all ok per IOMs, just replaced load/unload sol valves as appears pistion press/amp was increasing on a manual hold. Seems to have corrected the problem for a week an reoccured, this problem has been around since start up 10 years agoand has been limited at 80%. Any help or direction would be great( I did attend RTHB training)
