What to do if the Miller Coolmate 4 coolant system does not work?
- DDonna NguyenJul 28, 2025
If the coolant system isn't working, ensure the power cord is properly plugged into a working outlet. Also, inspect the line fuses or circuit breaker, replacing or resetting them if needed. If the motor overheated, the unit will automatically restart once it cools down. If problems persist, have a Factory Authorized Service Agent check the motor.
