Why won't my York Air Conditioner compressor and condenser fan start?
- A
  Adrienne RamirezJul 30, 2025
  Several factors can prevent your York Air Conditioner's compressor and condenser fan from starting. It could be due to a power failure, in which case you should call the power company. Alternatively, a blown fuse or tripped circuit breaker could be the cause; try replacing the fuse or resetting the breaker. Other potential causes include a defective thermostat, contactor, transformer, or control relay (replace the component), insufficient line voltage (determine and correct the cause), incorrect or faulty wiring (check the wiring diagram and rewire correctly), or a thermostat setting that is too high (lower the thermostat setting below room temperature).

Why is the head pressure too high in my York Air Conditioner?
- B
  Benjamin Carson MDAug 3, 2025
  Excessive head pressure in your York Air Conditioner can stem from several issues. The causes may be: a dirty air filter (replace the air filter), a dirty condenser coil (clean the coil), refrigerant overcharge (reclaim excess refrigerant), air in the system (reclaim refrigerant, evacuate & recharge), or condenser air restricted or air short- cycling (determine cause and correct).

What causes excessive suction pressure in a York Mr. Slim PK-1.6FLA?
- K
  Kimberly LeAug 7, 2025
  Excessive suction pressure in your York Air Conditioner could be due to a high head load (check for source and eliminate), compressor valves leaking (replace compressor), or refrigerant overcharge (reclaim excess refrigerant).

What to do if head pressure is too low in my York Mr. Slim PK-1.6FLA Air Conditioner?
- C
  Charles DeckerAug 11, 2025
  Low head pressure in your York Air Conditioner can be attributed to a low refrigerant charge (check for leaks; repair and recharge), a compressor valve leaking (replace compressor), or a restriction in the liquid tube (reclaim excess refrigerant).

How to stop my York Mr. Slim PK-1.6FLA Air Conditioner compressor from running constantly?
- J
  Joshua AcevedoAug 16, 2025
  If your York Air Conditioner's compressor is running continuously, several issues could be the cause. Check the following: a dirty air filter (replace it), the unit being undersized for the load (decrease the load or increase the unit size), a thermostat set too low (reset the thermostat), a low refrigerant charge (locate the leak, repair it, and recharge), leaking valves in the compressor (replace the compressor), air in the system (reclaim refrigerant, evacuate, and recharge), or a condenser coil that is dirty or restricted (clean the coil or remove the restriction).

What to do if my York Air Conditioner compressor keeps cycling on and off?
- G
  Glenn ReedAug 20, 2025
  If the compressor in your York Air Conditioner is cycling on and off more frequently than normal, it could indicate a problem. Possible causes include: refrigerant overcharge or undercharge (reclaim refrigerant, evacuate system, and recharge to nameplate), a defective compressor (determine the cause and replace), insufficient line voltage (determine cause and correct), a blocked condenser (determine cause and correct), a defective run/start capacitor, overload, or start relay (determine the cause and replace), a defective thermostat (replace thermostat), a faulty condenser fan motor or capacitor (replace), or a restriction in the refrigerant system (locate restriction and remove).

What causes my York Air Conditioner's condenser fan to run, but the compressor won't start?
- B
  Brittney SanchezAug 25, 2025
  If your York Air Conditioner's condenser fan is running but the compressor won't start, it could be due to faulty wiring or loose connections in the compressor circuit (check wiring and repair or replace), a compressor motor that is burned out, seized, or has an internal overload open (determine cause, replace compressor), a defective run/start capacitor, overload start relay (determine the cause and replace), or one leg of three-phase power dead (replace fuse or reset circuit breaker).
