The control system also requires an earth ground for proper operation of the control and flame-sensing electrode.

The 24-v circuit contains an automotive-type, 3-amp. fuse located on the control. (See Fig. 25.) Any shorts of the 24-v wiring during installation, service, or maintenance will cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp. fuse. The control LED will display status code 24 when fuse needs to be replaced.

Proper instrumentation is required to service electrical controls. The control in this furnace is equipped with a Status Code LED (Light-Emitting Diode) to aid in installation, servicing, and troubleshooting. It can be viewed through the sight glass in blower access door. The furnace control LED is either ON continuously, rapid flashing, or a code composed of 2 digits. The first digit is the number of short flashes, the second digit is the number of long flashes.

For an explanation of status codes, refer to service label located on blower access door or Fig. 45 and the troubleshooting guide which can be obtained from your distributor. The furnace control will store 1 status code for 72 hrs.

See Fig. 49, a brief Troubleshooting Guide.

1. To retrieve status code, proceed with the following:

NOTE: NO thermostat signal may be present at control, and all blower-OFF delays must be completed.

a.Leave 115-v power to furnace turned on.

b.Remove outer access door.

c.Look into blower access door sight glass for current LED status.

d.BRIEFLY remove insulated terminal wire from the draft safeguard (DSS) switch until LED goes out (1 to 2 sec), then reconnect it.

2.When above items have been completed, the LED flashes status code 4 times. Record this status code for further troubleshooting.

3.Component self-test will begin. Refer to component TEST section for complete test sequence.

4.Check LED status.

5.Refer to SERVICE label on front of the blower access door for more information.

6.Check LED status. If no previous faults in history, control will flash status code 11.

7.If LED status indicates proper operation, RELEASE BLOWER ACCESS DOOR SWITCH, reattach wire to R terminal on furnace control board, replace blower access door, and replace burner access door.

Step 2 —Care and Maintenance

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

Never store anything on, near, or in contact with the furnace, such as:

1.Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or other cleaning tools.

2.Soap powders, bleaches, waxes or other cleaning compounds, plastic or plastic containers, gasoline, kerosene, cigarette lighter fluid, dry cleaning fluids, or other volatile fluids.

3.Paint thinners and other painting compounds, paper bags, or other paper products.

For continuing high performance and to minimize possible equipment failure, periodic maintenance must be performed on this equipment. Consult your local dealer about proper frequency of maintenance and the availability of a maintenance contract.

!WARNING

ELECTRICAL SHOCK AND FIRE HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

Turn off the gas and electrical supplies to the unit and install lockout tag before performing any maintenance or service. Follow the operating instructions on the label attached to the furnace.

!WARNING

CARBON MONOXIDE POISONING AND FIRE HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

Never operate unit without a filter or with filter access door removed.

!CAUTION

CUT HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing, safety glasses and gloves when handling parts and servicing furnaces.

The minimum maintenance on this furnace is as follows:

1.Check and clean air filter each month or more frequently if required. Replace if torn.

2.Check blower motor and wheel for cleanliness each heating and cooling season. Clean as necessary.

3.Check electrical connections for tightness and controls for proper operation each heating season. Service as necessary.

4.Inspect burner compartment before each heating season for rust, corrosion, soot or excessive dust. If necessary, have furnace and burner serviced by a qualified service agency.

5.Inspect the vent pipe/vent system before each heating season for rust, corrosion, water leakage, sagging pipes or broken fittings. Have vent pipes/vent system serviced by a qualified service agency.

6.Inspect any accessories attached to the furnace such as a humidifier or electronic air cleaner. Perform any service or maintenance to the accessories as recommended in the accessory instructions.

CLEANING AND/OR REPLACING AIR FILTER

The air filter arrangement will vary depending on the application. The filter is exterior to the furnace casing.

NOTE: If the filter has an airflow direction arrow, the arrow must point towards the blower.
