Troubleshooting 

 

Problem 

 

Possible Cause 

 

 

 

Unit won’t work and is 

plugged in. 

 

Check plug input to unit, 

then check fuse. 

 

 

 

Unit will sift, but not 

pulse. 

 

Pulse timer inoperative.  

Call for technical support. 

 

 

 

Unit comes on, but will 

not sift or pulse. 

 

Make sure stack assembly 

is inserted correctly.  If 

the stack assembly is not 

the problem, the cam 

assembly may be out of 

alignment or the trigger 

spring may be broken. 

 

 

 

Unit works, but shuts off 

before timer hits zero. 

 

Stack assembly has not 

been unlatched. 

 

 

 

Unit works, but no light 

comes on. 

 

Replace the starter, which 

is located in the upper left 

hand corner of the 

chamber.  Also check the 

light bulb. 

 

 

 

Unit runs but lacks 

power. 

 

Possible defective driver 

or defective power 

transformer
