Why isn't the blower fan motor running on my CMAXX Dust & Fume Collector?

There are a handful of reasons that your blower fan motor may not be running. Let's break them down.

My blower fan motor is not starting.

• Improper motor wire size - Rewire using the correct wire gauges as specified by national and local codes.
• Motor not wired properly - See motor manufacturer's wiring diagram. Check and correct motor wiring for the supply voltage present. Follow wiring diagram and the National Electric Code.
• Motor not wired for available voltage - Check the power supply to the motor circuit on all leads.
• Input circuit down - Check the power supply to the motor circuit on all leads.
• Electrical supply circuit down - check the power supply circuit for proper voltage. Check for any fuse or circuit breaker fault.

My blower fan motor starts, but does not stay running.

• Incorrect motor-starter installed - Check for the proper motor starter and replace if necessary.
• Blower fan damper control not adjusted properly - Check airflow in duct. Adjust damper control until proper airflow is achieved and the blower motor's amp draw is within the manufacturer's rated amps.
• Electrical circuit overload - Check that power supply circuit has sufficient power to run all the equipment.
