Ultimate Guide to Repairing Ice Machines: Tips and Tricks

Tutorial Technology Tutorials

Learn the step-by-step process of repairing ice machines efficiently and effectively. From identifying issues to completing repairs, this guide covers everything you need to know to keep your ice machine running smoothly.

Diagnosing the Problem

⚙️Identified restricted cool vapor valves causing harvesting issues.

🔧Replacing cool vapor valves, thermostar, and dryer to fix the machine.

⚠️Considering whether to pull down the entire machine based on recovery difficulty.

Repair Process

🔥Brazing in valves and worrying about drain pan and foam insulation.

🔌Disconnecting drain, thermostat wire, and planning to shift the machine for easier access.

Soldering Techniques

🛠️Manipulating and soldering components into the valve

🔩Using a wrench to move a component and carefully soldering it into place

💧Ensuring the solder is liquefied and properly set in place

Maintenance and Charging

🔋Assembling and charging the ice machine with 200 oz of refrigerant

🧼Purging and sanitizing the ice machine before continuing to charge it

FAQ

What type of solder should be used for brazing stainless steel valves?

15% silfos solder is recommended for brazing stainless steel valves.

Is flux necessary when using silfos solder?
