Self-contained & Remote Condenser Single

Expansion Valve Machines - Comparing

Evaporator Inlet and Outlet Temperatures

The temperatures of the suction lines entering and

leaving the evaporator alone cannot diagnose an ice

machine. However, comparing these temperatures

during the freeze cycle, along with using Manitowoc’s

Freeze Cycle Refrigeration System Operational

Analysis Table, can help diagnose an ice machine

malfunction.

The actual temperatures entering and leaving the

evaporator vary by model, and change throughout the

freeze cycle. This makes documenting the “normal”

inlet and outlet temperature readings difficult. The key

to the diagnosis lies in the difference between the two

temperatures five minutes into the freeze cycle. These

temperatures should be within 7° of each other.

Use this procedure to document freeze cycle inlet and

outlet temperatures.

1. Navigate to Service / Real Time Data / Time &

Temp / T3 & T4 Thermistors (See page 79

Service Menu Navigation for details).

2. Wait five minutes into the freeze cycle.

3. Record the evaporator inlet (T3) and outlet (T4)

temperatures at 5 minutes into the freeze cycle.

Determine the difference.

4. Record the information on the table.
