BEFORE Y OU REQUEST A

SERVI CE CALL

If your furnace is not operating or not performing properly, you

may save the expense of a service call by checking a few things

yourself before calling for service.

For Insufficient Airflow:

Check for dirty air filter(s).

S Check for blocked return-- air or supply --air grilles

throughout your home. Ensure they are open and

unobstructed.

If problem still exists, call your dealer for service.

If Furnace Fails to Operate:

Follow this checklist step by step, advancing to the next step only

if furnace fails to start.

S Check thermostat for proper temperature. Is thermostat

set above room temperature?

S Is thermostat set on HEAT?

S Check fuses and circuit breakers. Is electrical supply

on?

S Is manual shutoff valve in gas supply pipe in open

position? (Follow start-- up procedures if you open gas

valve.)

NOTE: Turn off electrical supply before continuing with

checklist.

S Is control switch on gas valve in ON position? (Follow

startup procedures if you must reset switch to ON

position.)

S Check manual reset flame rollout switch located on the

burner box. If furnace has experienced high

temperature conditions, this switch will shut off the

furnace. Reset it by pushing the button on the switch. If

it trips again, shut down the furnace and call for

service. See “Shutting Down Your Furnace” section in

this manual.

S Check for obstructions around the vent termination

outside the structure.

If the furnace still fails to operate, call your service representative.

For your convenience, record the furnace product and serial

numbers on back page. Should you ever require service, you will

have ready access to the information needed by your service

representative.

This furnace has a light--emitting--diode (LED) status code

display to aid the installer, service technician, or homeowner

while installing or servicing the unit. The LED code can be seen

by removing the main furnace door and viewing the LED

through the view port in the blower access panel. (See Fig. 2.)
