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.
3. Verify the unit is
