YORK, At a Glance

YORK has been an industry leader in HVAC systems since it was founded in 1874. Many of its products are found in some of the world’s most iconic structures, including the Empire State Building and the Sydney Opera House. This comprehensive YORK furnace repair guide will show you how to diagnose and troubleshoot almost any performance issue that your YORK furnace might begin to experience.

There’s one task in particular that will guarantee long-term efficiency for your YORK furnace, regularly changing the air filters. This simple practice will ensure that your unit’s internal components, such as the blower motor and the pressure tubing, continue to function at their best. Furthermore, it’s important to vacuum the vents, check the registers, and keep the area surrounding your YORK furnace clear of debris.

How to Replace Your YORK Air Filter

  1. Before you can replace your filter, check the access panel for the exact filter size as well as the part number.
  2. When ready, open the filter access panel.
  3. Remove the old filter, which should be located near the return air duct and blower.
  4. Insert the new air filter, remember to make certain that it’s installed in the same direction as the previous one.
  5. Replace the filter access panel.

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/FuseEither 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.
IgniterThe 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?ThermostatThe 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 MotorThe 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 BoardThe 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.
ThermostatThe 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 SensorYour 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 CodeWhat this meansHow to fix it
Slow green flashThis is normal operation.N/A
Slow amber flashThis is normal operation with a call for heat.N/A
Rapid red flashThis is a twinning error, incorrect 24V phasing.You should check the twinning wiring.
Four amber flashesThe 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 flashFlame sensed when there was no call for heat.You should check for a leaky or slow closing gas valve.
Two red flashesThe 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 flashesMany issues could cause this.Check for a faulty inducer, blocked vent pipe, broken pressure switch hose, or a faulty pressure switch.
Four red flashesThe 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 flashesThe 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 flashesAfter 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 flashesThe 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 flashesThe 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 flashesThe 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 flashesA flame has been sensed with no call for heat.You should check the gas valve as well as the gas valve wiring.
Eleven red flashesThis 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 flashesThis indicates an open igniter circuit.You should check for a disconnected or loose wire, or a cracked or broken igniter.
Steady redThis is a control failure.You should replace the control board.

When to Get a Technician for YORK Furnace Repairs

It’s tough to know when exactly is the right time to contact a trained HVAC technician to look at your YORK furnace. Although you can diagnose many of the issues on your own, performing the repairs is a much more complex task. If you experience any of the following issues, you should contact trained heating and cooling professional to save you money in the long run.

  • If your YORK furnace begins to spontaneously leak or drip.
  • If your unit stops producing heat.
  • Strange noises begin to come from your YORK furnace, such as banging, whistling, gurgling, etc.
  • If you’re noticing that your boiler is acting strange, and your furnace is continuously turning itself on and off.

Who to Call For YORK Furnace Repairs

Our certification requires that companies meet a wide array of criteria to make sure that Canadian homeowners are receiving the best service available.
