What’s Wrong With Your YORK Furnace?
Common Furnace Problems and Troubleshooting
Before attempting any diagnosis or repair, make sure to shut off furnace power completely before completing YORK furnace repairs.
|Is your furnace...||The problem might be your...||What's wrong?||How you can fix it:|
|Not heating?||Circuit Breaker/Fuse||Either the furnace's electrical system has shorted, or the power switch has blown.||To fix this, you'll have to reset your furnace's circuit breaker. However, if the switch has blown, you'll have to replace it.|
|Igniter||The igniter in your furnace is either cracked or defective.||Check the igniter for cracks, if you find some then you'll have to replace it. Otherwise, test the igniter with a multimeter for continuity to see if it's defective.|
|Cycling irregularly?||Thermostat||The furnace's thermostat is adjusting incorrectly.||If your thermostat has an adjustable calibration scale, use it to adjust the heat anticipator. If this doesn't work or you don't have a scale, you should replace the thermostat altogether.|
|Not blowing hot air?||Blower Motor||The furnace's blower motor has either burnt out or is running improperly.||If you notice that power's reaching the motor but it still isn't operating, you'll have to replace it. However, if it runs but the air doesn't move, the connecting belt has broken. You should replace the belt.|
|Blowing too much air?||Control Board||The furnace is sending an improper amount of voltage to the blower motor due to a failed relay on the control board.||You should replace the control board.|
|Thermostat||The contact that controls the blower motor on your thermostat is stuck.||You should use a multimeter to check for continuity. If it isn't operating correctly, you'll want to replace the thermostat.|
|Starting and then stopping shortly after?||Flame Sensor||Your furnace's flame sensor is either dirty or defective. This means that it's unable to sense whether a flame is present.||You should use an excellent abrasive pad to clean the sensor if it's dirty. If it isn't dirty, you must replace the flame sensor entirely.|
YORK Furnace Error Codes
|Error Code||What this means||How to fix it|
|Slow green flash||This is normal operation.||N/A|
|Slow amber flash||This is normal operation with a call for heat.||N/A|
|Rapid red flash||This is a twinning error, incorrect 24V phasing.||You should check the twinning wiring.|
|Four amber flashes||The control is receiving a "Y" signal from the thermostat without a "G" signal, and this indicates that the thermostat is wired incorrectly.||You should check the thermostat wiring.|
|One red flash||Flame sensed when there was no call for heat.||You should check for a leaky or slow closing gas valve.|
|Two red flashes||The pressure switch contacts that are normally open are stuck in the closed position.||You should check for a faulty pressure switch, miswiring, or an open pressure switch contact that didn't close after the inducer was energized.|
|Three red flashes||Many issues could cause this.||Check for a faulty inducer, blocked vent pipe, broken pressure switch hose, or a faulty pressure switch.|
|Four red flashes||The contacts on the main limit switch that are normally closed have opened.||You should check for a dirty filter, an improperly sized duct system, an incorrect blower speed setting, an incorrect firing rate, or a faulty blower motor.|
|Five red flashes||The contacts that are normally closed have opened during the rollout switch. The rollout control is manually reset.||If it has opened, you should check to see if there's a proper supply of combustion air. Otherwise, you can inspect the inducer's operation, the primary heat exchanger for a sign of failure, or the burner for potential issues. Remember to reset the switch and cycle power to the control.|
|Six red flashes||After the unit began operating, the pressure switch opened four times during the call for heat.||The furnace will lockout for 1 hour and then restart.|
|Seven red flashes||The flame could not be established. The no-light condition occurred three times during the call for heat before locking out.||You should check for low gas pressure, a faulty gas valve, a dirty or defective flame sensor, a faulty hot surface ignitor, or the burner for potential issues. The furnace will lockout for 1 hour and then restart.|
|Eight red flashes||The flame has been lost five times during the heating cycle.||You should check the system for low gas pressure, a dirty or faulty flame sensor, or a defective burner. The furnace will lockout for 1 hour and then restart.|
|Nine red flashes||The line voltage polarity has been reversed or there's a grounding problem.||You should check the furnace grounding and the polarity at both the furnace and branch.|
|Ten red flashes||A flame has been sensed with no call for heat.||You should check the gas valve as well as the gas valve wiring.|
|Eleven red flashes||This is usually caused by a failed blower motor or blower wheel.||After correcting the failure condition, you will want to cycle power to the control which will reset the hard lockout condition.|
|Twelve red flashes||This indicates an open igniter circuit.||You should check for a disconnected or loose wire, or a cracked or broken igniter.|
|Steady red||This is a control failure.||You should replace the control board.|
