Why does my York Air Handler blower run all the time?
- L
  luiswatsonAug 9, 2025
  If the blower in your York Air Handler is running continuously, here's what might be happening and how to address it: * **Thermostat Setting:** Ensure that the thermostat fan switch is set to the “AUTO” position, not “ON”. * **Blower Delay:** The blower might be in its normal OFF delay, which lasts approximately 1 minute. Wait and see if it stops. * **Connectors and Limits:** Check the installation of the 6-pin connector. Also, inspect the limit switch connection. * **Variable Speed Tab:** Look for a broken variable speed break-out tab.

What to do if my York Air Handler has no heat or limited heating?

  Christopher Murray DDSAug 14, 2025
  If your York Air Handler isn't providing enough heat, or no heat at all, here are a few things to check: 1. **Airflow:** Make sure that all registers are open and that there are no obstructions restricting airflow to either the supply or return registers. 2. **Filter:** Inspect the filter and replace it if it's dirty. 3. **Blower Motor:** Check to ensure the blower motor is functioning correctly. 4. **Safety Limit:** If the safety limit has opened 4 times, the control will prevent the heating element from operating for 1 hour. Allow the control to reset.
