Troubleshooting 

The fan motor will not run 

 

Reset the thermal cutout on the fan motor. Allow the motor to cool. 

 

Check the wiring. 

 

Test the power at the control using a voltmeter. 

 

Replace the fuse. If the fuse blows immediately then there is a problem with the wiring or the fan motor. If the 
fuse blows after a delay (minutes, hours, for example), the load exceeds the current rating of the control. 

 

The fan motor growls 

 

Make sure the motor is working by disconnecting the wire at 

terminal 1

 and 

terminal 4

 and then connect these 

lines together. The fan should run at full speed. 

 

Make sure excessive electrical noise is not being induced onto the temperature sensor by using a short sensor, 
the standard one-foot one included with the control will work. 

 

The Temperature knob will not control the fan speed 

 

Check the sensor wiring.  

 

Replace the temperature sensor (part number MT-P3) if the motor runs at idle or full speed regardless of the 
temperature setting. 

Contact your dealer if this guide fails to resolve your problem.
