York Heat Pump Outdoor Fan Not Spinning: Causes & Fixes

York heat pump outdoor fan not spinning: what it means

“Outdoor fan not spinning” is a symptom, not a numbered fault code. Some York outdoor control boards log related faults, which you can see as LED flash codes on the board inside the service panel. The meanings of those codes vary by model, so a technician should read them from the wiring diagram label on that specific unit.

The outdoor fan pulls air across the outdoor coil. That airflow lets the heat pump absorb heat in winter and reject heat in summer.

Normal behavior to rule out first. During defrost, a York heat pump intentionally stops the outdoor fan while the compressor keeps running. This usually lasts a few minutes, often with steam and a whooshing sound when the reversing valve shifts. If the fan resumes on its own, there is no problem. If you suspect the unit is stuck in defrost, see our separate page on that topic.

When it is a real fault. Treat it as a fault if:

• the fan stays off while the compressor hums or runs,
• the fan is off in cooling mode, or
• the fan only turns after being nudged.

Shut the system off at the thermostat if any of these apply. The compressor’s internal overload resets automatically once it cools, but running repeatedly without the fan damages it. There is no lockout to clear for this symptom itself. Board-logged faults on some models clear when the fault condition clears or when power is cycled.

York heat pump outdoor fan not spinning: common causes, ranked by probability

1. Failed run capacitor (PSC-motor models). This is the most common cause by far. The capacitor may be a dual capacitor shared with the compressor or a separate fan capacitor. Typical signs:
   • the fan hums but won’t start,
   • the fan starts slowly, or
   • the fan runs only after a push.
2. Failed condenser fan motor. The bearings seize or the windings open. The motor’s internal thermal protector may also trip, making the motor run intermittently and then quit when hot.
3. Contactor problems. On many single-stage units, the fan and compressor share the contactor. Pitted or burned contacts, or a failed contactor coil, can leave the fan dead. Often the compressor is affected too, or one leg feeds the fan poorly.
4. Defrost control / outdoor board fault. The board switches the fan off for defrost through a relay, so a failed fan relay or board can keep the fan off. Communicating and variable-speed York models also send the ECM motor its run signal from the board.
5. Wiring faults. Possible faults include a burned or loose fan lead, a rodent-chewed wire, or a corroded connection at the capacitor, contactor or board.
6. Obstruction or a damaged blade. Ice, debris, or a bent blade can rub the shroud or guard. In winter, ice buildup can physically lock the blade.
7. No power to the outdoor unit. A tripped breaker or pulled disconnect stops both the fan and the compressor. The indoor blower may still run.

How to fix York heat pump outdoor fan not spinning: safe checks first

• Check whether it’s defrost. In heat mode on a cold day, wait 10 to 15 minutes. If steam rises and the fan restarts, the system is working normally.
• Check the thermostat. Confirm the mode (Heat or Cool) and that the setpoint actually calls for operation. Replace the batteries if the display is dim or blank.
• Check the breakers. Look for a tripped double-pole breaker labeled for the heat pump or condenser. Reset it once. If it trips again, leave it off and call a technician.
• Check the outdoor disconnect. Confirm that the pull-out or switch disconnect next to the unit is fully seated in the ON position. Do not open the electrical box beyond that.
• Replace a dirty indoor air filter. A clogged filter doesn’t stop the outdoor fan, but it stresses the whole system. Fix it while you’re at it.
• Look from outside the guard only. You can clear leaves, snow drifts or debris piled against the unit from the outside. Keep 2 feet of clearance around it. Never reach through the fan guard, and don’t chip ice off the coil or blade.
• Shut it off if the fan is still dead. If the compressor runs or hums with the fan stopped, set the thermostat to Off. Switch to emergency/auxiliary heat if you need heat, then call a technician.

How a technician will diagnose it

Use this sequence to sanity-check what a technician tells you:

1. Confirm the call and the mode. Verify the thermostat call and the operating mode, and rule out normal defrost.
2. Check supply voltage. With the disconnect pulled and lockout applied, they’ll inspect for burned wires. Then they’ll measure line voltage at the contactor.
3. Test the capacitor. They’ll discharge the capacitor and measure it in microfarads with a meter. A reading more than about 6% below its rating, or a bulged or leaking case, means it should be replaced.
4. Test the motor. They’ll check winding resistance and look for an open circuit or a short to ground. They’ll also spin the blade by hand with power locked out to feel for seized or rough bearings, and note whether the motor is hot and tripped on its thermal protector.
5. Inspect the contactor. They’ll look for pitting on the contacts and check coil voltage (24 V) and voltage across the contacts.
6. Check the defrost/outdoor board. They’ll read any LED fault codes against the unit’s diagram. They’ll confirm whether the board’s fan output (the relay contacts, or the ECM signal on variable-speed models) is energized when it should be.
7. Check for refrigerant-side damage. If the unit ran long without the fan, they may check compressor amps and system pressures.

A good technician will tell you the measured capacitor value and the motor test results. Be skeptical of a quote to replace a motor without a capacitor test first, since a capacitor is much cheaper.

Symptom, cause and what to do

York heat pump outdoor fan not spinning repair cost

Typical US installed prices (parts plus labor) are listed below. Costs vary by region, warranty coverage and after-hours rates.

York’s parts warranty, often 5 or 10 years when the unit is registered, may cover the motor or board. If so, you pay labor only, so check your registration before paying for parts.
