Troubleshooting - Carrier 38QRR Owner's Information Manual

TROUBLESHOOTING
Before you request dealer service, check for these easily solved
problems:
• Check the indoor and outdoor disconnect switches (see Fig.
1.) Also check your main electrical panel circuit breakers or
fuses.
• Check for sufficient airflow. Air filter(s) should be
reasonably clean and interior vents should be open and
unobstructed.
• Check thermostat settings. For cooling, your desired
temperature setting should be LOWER than the displayed
room temperature, and the System/Mode control should be
on Cool or Auto. For heating, your temperature setting
should be HIGHER than the displayed room temperature,
and the System/Mode control is set to Heat or Auto.
• Time delays - depending on the Carrier Heat Pump model
you have, there may be delays in unit operation that are
built-in to protect the equipment and your comfort. Don't be
alarmed if you notice a time delay in operation. It may be a
standard protection feature of your equipment. Check with
your Carrier Dealer for more informationon time delays.
If you need to contact your Carrier dealer for troubleshooting
and/or repairs, be sure to have the model and serial numbers of
your equipment available (there are spaces on the cover for you to
write this information). With this information, your dealer may be
able to offer helpful suggestions over the phone or save valuable
time through knowledgeable preparation for the service call.
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your home
comfort system should be inspected regularly by a properly trained
service technician. Many dealers offer this service at a reduced rate
with a service contract. Some service contracts offer additional
benefits such as parts discounts and no additional charge for "after
hours" or emergency service.
Your annual system inspection should include:
• Routine inspection of air filter(s) with replacement or
cleaning as required
• Inspection and cleaning of the blower wheel housing and
motor
• Inspection and, if required, cleaning of indoor and outdoor
coils
• Inspection of the indoor coil drain pan, as well as the primary
and secondary drain lines. If the system has an auxiliary
drain pan and line. they should be inspected at this time as
well. Service should include cleaning if required.
• Check all electrical wiring and connections
• Check for secure physical connections of individual parts in
each unit
• Operational check of the Heat Pump system to determine
actual working condition. Necessary repair and, or
adjustment should be performed at this time.
