Cooler Operation: 

(cont.) 

N-E5 Electronic Control Module Operation: 

(cont.)  

 

The N-E5 controller is fitted with an internal 8 Amp fuse to protect the PCB circuitry. 
 
The 8 Amp fuse will protect the N-E5 controller from short circuit and/or high current 
draw, on the following circuits: 

•

 

Pump 

•

 

Water inlet solenoid 

•

 

Fan motor 

•

 

PCB relays 

 

Important Note: 

The N-E5 internal 8 Amp fuse does not protect the control against short circuit on the 
ServoSeal / drain valve motor circuit. 
 
The N-E5 controller will maintain a minimum voltage on the output to the water inlet 
solenoid in the OFF cycle.
