Status LED Condition Status LED Description Status LED Troubleshooting Information
*Flash code number corresponds to a number of LED flashes, followed by a pause, and then repeated. Reset ALERT flash code by removing 24VAC power from monitor; last code will display for 1 minute after monitor is powered on.
NOTE − Code 8 is not used.
Maintenance
The GCSX15 unit should be inspected annually by a qualified service technician to ensure proper operation.
Filters
Not supplied. Inspect once a month. Replace disposable, or clean permanent−type, as necessary. DO NOT replace permanent type with disposable.
Distorted flame or yellow tipping of the natural gas flame (or long yellow tips on LP/propane flame) may be caused by one or more of the following: lint or dirt inside the burner or burner ports; lint or dirt at the air inlet between the burner and manifold pipe; or an obstruction over the burner orifice.
Use a soft brush or vacuum to clean the affected areas.
Motors
Indoor, outdoor fan and vent motors are permanently lubricated and require no further lubrication. Motors should be cleaned yearly to prevent the accumulation of dust and dirt on the windings or motor exterior.
Coil
Dirt and debris should not be allowed to accumulate on the coil surfaces or other parts in the air conditioning circuit. Cleaning should be performed as often as necessary. Use a brush, vacuum cleaner attachment, or other suitable means. If water is used to clean the coil, be sure the power to unit is shut off prior to cleaning.
NOTE − Care should be used when cleaning the coil so that the coil fins are not damaged.
Do not permit the hot condenser air discharge to be obstructed by overhanging structures or shrubs.
To Clean Burners
Light the burners and allow unit to operate for a few minutes to establish normal burning conditions. Observe the burner flames. Compare this observation to figure 16 to determine if flame is properly adjusted. Flame should be predominantly blue in color and strong in appearance. Verify that all burners are lit and that the flame does not impinge on the sides of the heat exchanger.

Vent Outlet
Visually inspect vent outlet periodically to make sure that the there is no buildup of soot and dirt . If necessary, clean to maintain adequate opening to discharge flue products.
Planned Service
You should expect a service technician to check the following items during an annual inspection. Power to the unit must be shut off for the service technician’s safety.
S Fresh air grilles and louvers Must be open and unobstructed to provide combustion air.
SBurners must be inspected for rust, dirt, or signs of water.
SExhaust pipe must be inspected for signs of water, damaged Rust or disconnected joints.
SUnit appearance must be inspected for rust, dirt, signs of water, burnt or damaged wires, or components. A good coat of auto wax can extend the appearance.
SBlower access door must be properly in place.
SReturn air duct must be properly attached and provide an air seal to the unit.
SOperating performance
during operation to monitor proper performance of the unit and the vent system.
SCombustion gases s must be analyzed and compared to the unit specifications.
Problems detected during the inspection may make it necessary to temporarily shut down the furnace until the items can be repaired or replaced.
Pay attention to your unit. Situations can arise between annual furnace inspections that may result in unsafe operation. For instance, items innocently stored next to the unit may obstruct the combustion air supply. This could cause incomplete combustion and the production of carbon monoxide gas.
