York Furnace Troubleshooting Guide

Check the troubleshooting tips to solve York ignitor, gas valve, blower motor problems, and error codes.

York Furnace Ignitor Troubleshooting

If your York furnace ignitor is not working, you can follow these troubleshooting tips.

  • First power off the furnace and remove the top panel of the furnace.
  • Now, locate the ignitor in the upper right.
  • Remove the screws that hold the ignitor in place.
  • Unplug it from the wires and pull it out.
  • Check for cracks on the ignitor. Sometimes, these cracks are very small to see. If there is any crack, consider it as bad. If you don't see cracks, examine whether the ignitor is getting power.
  • To check power, turn the power switch on, then the inducer motor should start.
  • Place the meter leads into the plug, one in each hole inside of the unit. Make sure not to place the leads so far into the plug as the connectors got damaged and spread out. Now, examine your meter. If it shows +/-120 volts, then the ignitor is getting power that means your ignitor is bad.
  • In addition, you can check this in the ohms setting. Set the meter to the ohms. Connect the leads, one to each side of the ignitor plug. Your meter should display a reading between 40 and 200+ ohms. If it's not showing any ohms reading, you have to confirm that it is bad. So, think about York furnace ignitor replacing.

Solutions for York Furnace Blower Motor Problems

Here are some basic furnace blower troubleshooting tips.

  • See if the circuit breaker has tripped. If it is tripped, reset and allow some time for a normal operating cycle.
  • Check for the thermostat is set correctly. If it has set to low, you may get cold air but your furnace thinks that everyone is cozy at 50 degrees.
  • Check the furnace filter. Ensure that it always be cleaned or replace monthly. A clogged furnace filter may drop airflow so much and the furnace overheats without sending the heat into your house.

If you have still cool air but a steady airflow, then consider blower motor is working but the heat exchanger or burner is damaged. So, check for the furnace flame for a complete blue color. If red, yellow, or orange comes, it indicates that dust and dirt are build up on the burner. Also, inspect the heat exchanger for cracks.

Finally, you have to test the blower fan when all the above possible solutions are not worked. Turn the furnace off and set the thermostat to "fan-only" mode. Wait a few minutes. If the fan turns on, the blower motor is not the culprit. If it doesn't start, there might be a wiring issue or motor problem. Contact an authorized repair person to solve the problem correctly.
