What to do if my Multifan Fan does not start?
If your Multifan Fan doesn't start, first, check that power is being supplied by checking all power supplies, the fuse or circuit breaker, and the cabling. Also, switch on the controller. If a Variable Frequency Drive (VFD) is present, check it according to the manufacturer's instructions.
Why does my Multifan Fan motor overheat while running?
If your Multifan Fan motor overheats while running, check for overloading of the fan system by ensuring the intake or exhaust is not blocked. Also, ensure the fan motor is clean of any dirt in the cooling fins.
