Service Diagnostic Tips

A prime requisite on the initial contact is: Always allow the customer to explain the problem. Many times the trouble

can be diagnosed more quickly, based on the customer’s explanation. Most of all, do not jump to

conclusions until you have heard the full story and have evaluated the information obtained from the customer. Then

proceed with your diagnosis.

Before starting a test procedure, connect the product service cord to the power source, through a wattmeter,

combined with a voltmeter. Then make a visual inspection and operational check of the air conditioner to determine

the following:

1. Is the product properly leveled?

2. Is the product located for proper dissipation of heat from the condenser? Check install location.

3. Feel condenser. With compressor in operation, condenser should be hot, with gradual reduction in temperature

from entry to exit of condenser.

4. Is evaporator fan properly located on motor shaft?

5. Is the thermostat sensing element properly positioned?

6. Observe frost pattern on evaporator.

7. Check control setting.

For air-conditioners, check room size, temperature, amount of people, windows, and other factors that increase the

load on the product. After this phase of diagnosis is completed, a thorough operational check should be made of the

refrigeration system.

Definitions

Recovery:

To remove refrigerant in any condition from a system and store it in an external container without necessarily testing

or processing it in any way.

Recycling:

To clean refrigerant for reuse by oil separation and single or multiple passes through devices, such as replaceable

core filter-driers, which reduce moisture, acidity and particulate matter. This term usually applies to procedures

implemented at the field job site or at a local service shop.

Reclaim:

To reprocess refrigerant to new product specifications by means which may include distillation, will require chemical

analysis of the refrigerant to determine that appropriate product specifications are met. This term usually implies the

use of processes or procedures available only at a reprocessing or manufacturing facility.
