Thermal LED is ON

1.

Improper fan operation.

1. Check for proper fan operation.

 

 

 

 

 

 

Fan should run in a low speed

 

 

 

 

 

 

setting when the machine is idle

 

 

 

 

 

 

and in a high speed when the

 

 

 

 

 

 

output is triggered. Check for

 

 

 

 

 

 

material blocking intake or

 

 

 

 

 

 

exhaust louvers, or for excessive

 

 

 

 

 

 

dirt clogging cooling channels in

 

 

 

 

 

 

machine.

 

 

 

 

 

 

 

 

 

 

 

2.

Open thermostat circuit.

2. Check for broken wires, open

 

 

 

 

 

 

connections or faulty thermostats

 

 

 

 

 

 

in the thermostat circuit.

1.

Control PC Board Battery.

1. Replace the battery (Type:
