Good morning guys, I'm having some trouble with one of my lifts model: 8FGCU32 here at work that was having overheating issues. First it just showed the code 04-1 which is the temperature sensor abnormality which actually ended up being a broken wire to the sensor. So anyway I changed the thermostat and coolant temp sensor (before discovering broken wire) and the code went away. Now the lift shows that the temperature is overheating with no other indication but the regulator I noticed is actually icing up where the coolant liquid runs through the regulator (bottom of regulator) coming off behind the water pump on the engine.
