Why does my York Air Conditioner fan motor run intermittently?
- T
  Traci RoblesAug 26, 2025
  An intermittent fan motor in your York Air Conditioner may be due to: * Cycles on overload. Check the voltage, and if it's not within limits, call an electrician. * Faulty capacitor. Test the capacitor and replace it if it's not within +/-10% of the manufacturer's rating. * Worn bearings. Check the bearings and replace the motor if the fan blade cannot rotate freely. * Speed change issue. Observe if there's any change from high speed to low speed; replace the motor if the speed does not change.

- F
  Frank AndersonSep 3, 2025
  If the fan motor runs but the compressor doesn't, check the following: * Voltage: If it's not within limits, contact your supply authority. * Wiring: Look for loose connections; repair or replace terminals as needed. Refer to the wiring diagram for correct wire placement. * Main switch: Check for failure and replace if necessary. * Capacitor: Test the capacitor and replace it if it's not within +/-10% of the manufacturer's rating or if it's shorted, open, or damaged. * Thermostat: Ensure the thermostat is set to the coolest setting in cooling mode or the warmest in heating mode. * Compressor: Check the compressor for an open circuit or ground and replace it if necessary.

What could cause the York Y9USC-09 B5R fan motor to make noise?
- M
  Melissa VargasSep 8, 2025
  Fan motor noise in your York Air Conditioner can be caused by: * A cracked, out-of-balance, or partially missing fan. Replace the fan if any of these conditions are present. * A cracked, out-of-balance, or partially missing blower. Replace the blower if any of these conditions are present. * Loose screws. Tighten them. * Worn bearings. Replace the motor if knocking sounds continue when running or are loose, or if the motor hums or the noise appears to be internal while running.

Why is my York Air Conditioner not cooling or heating properly?
- A
  Anthony WilliamsNov 15, 2025
  There are several reasons why your York Air Conditioner might not be cooling or heating effectively: * The air filter may be restricted and needs cleaning or replacement. * The vent door may be open and needs closing. * The unit might be undersized for the area. * The condenser and evaporator might be restricted and need cleaning or replacement. * The fan motor capacitor might be outside of the +/-10% range of the manufacturer's rating and needs to be checked. * Gaps in the room structure may need sealing. * Airflow might be blocked. * The condenser might be exposed to sunlight and need an awning. * There might be insufficient refrigerant due to leaks. * The capillary tube might be blocked or leaking. * The compressor inlet and outlet valve may be damaged. * There ...
