BEFORE YOU CALL FOR SERVICE, CHECK FOR SEVERAL
EASILY-SOLVED PROBLEMS
If insufficient heating or cooling is suspected:
( ) Check for sufficient airflow. Check the air filter for dirt.
Check for blocked return-air or supply-air grilles. Be sure they
are open and unobstructed. If these checks do not reveal the
cause, call your servicing dealer.
If your unit is not operating at all, check the following list for
easy solutions:
( ) Check to be sure that your thermostat temperature selector is set above the indoor temperature during the heating
season, or below the indoor temperature during the cooling
season. Be sure the system switch is in the proper HEAT or
COOL position and not in the OFF position.
( ) Is the electrical supply switch ON? Are any fuses blown,
or has the circuit breaker tripped?
( ) During the heating season, check the external manual
shutoff valve. Is this lever parallel with the pipe, indicating
that the valve is open? Or is the lever at a right angle,
indicating that the valve is closed? If closed, has the gas been
shut off for safety reasons? Otherwise, you may open the valve
and follow the start-up procedures listed in this manual.
NOTE: Before proceeding with the next check, turn OFF the
gas supply, then the electrical power supply to the unit. Remove the control access door.
( ) During the heating season, check the control dial on the
internal gas valve. Is it in the ON position? If it is not, be
sure it was not turned off for the purpose of safety.If no safety
hazards exist, follow the start-up procedures in this manual.
( ) If your unit still fails to operate, call your servicing dealer
for troubleshooting and repairs. Specify the model and serial
numbers of your unit. (Record them in this manual in the
space provided.) If the dealer knows exactly which unit you
have, he may be able to offer suggestions over the phone, or
save valuable time through knowledgeable preparation for the
service call.
IN CASE OF TROUBLE
If after performing the above and unit performance is still
unsatisfactory, shut off the unit and call your dealer.
