The fuse is located on the noise filter. 

1. 

Disconnect power and remove grille and Assembly 

Control Box. 

2. 

Replace the fuse. 

3. 

When 20A fuse blows out by the operation of interlock 

monitor switch failure, replace the primary interlock 
switch, secondary interlock switch, door sensing switch, 
interlock monitor switch and power relay. 

4. 

When the above four switches operate properly, check 

if any other part such as the control circuit board, blower 
motor or high voltage transformer is defective.
