Failures In The Scraping Beating
System
• Beater Low triggers a defrost cycle, caused by following:
– Low brix, rapid freeze and scrapper blades can’t keep up with the freezing speed
– Low refrigerant, over freeze in the back of barrel
– Worn beater blade, won’t scrap well and thick ice layer
– Failed capacitor, low baseline and high beater %
– Worn motor gear (motor failure), low baseline and high beater %
– Bad motor winding (motor failure), low baseline and high beater %
• Rapid compressor cycles
– Low refrigerant, false recognition of beater % when freezing
– Worn beater blade, false recognition of beater % when freezing
– Low brix, false recognition of beater % when freezing
