This document provide two levels of support; customer advice provides information that meant to be shared with the customer

explaining possible operation issues that may be creating problems. Service assistance provides solutions for the technician servicing

the product in the home. Also included are applicable primary and secondary parts recommendations. The primary part listed is

expected to be the solution in 80% of the repairs with that symptom. The idea of the document is to provide the technicians with

repair advice that can be used to improve the first time fix ratio as well as reduce “shotgun” troubleshooting.

Air conditioner

seems to run

too much or

over cycle

The use of more efficient

components may cause the air

conditioner to run longer than

an older model, but the total

energy consumption will be

less.

Newer air conditioners do not

emit the “blast” of cold air you

may be accustomed to from

older air conditioners, but this

is not an indication of lesser

cooling capacity or efficiency.

A higher capacity air

conditioner may be required,

depending on the size of the

room being cooled.

1. Verify the thermostat

is cycling the unit on and

off properly.

2. Inspect the wiring to

the Control PCB.
