Payne Central air conditioner has poor temperature control
Payne central air conditioner poor temperature control can show up as uneven cooling in the house, AC temperature swings, or an air conditioner not holding the thermostat setting. Start with the air filter, the most likely cause: a clogged filter restricts airflow through the furnace or air handler, lowers cooling capacity, and can frost the evaporator coil. Replace it as directed, at least twice yearly and more often with pets or dusty conditions. Next, test the wall thermostat and, if equipped, the wall thermostat. Failed thermostat contacts can keep the air handler or condensing unit from operating correctly or cause intermittent cooling; a multimeter continuity test can confirm a defective thermostat. Less commonly, a heavily clogged filter, blocked or leaking vents, or an oversized air conditioner can cause uneven temperatures because air does not circulate long enough or evenly. Check accessible filters and vents yourself, but turn off power before testing or replacing a thermostat. Leave 240-volt electrical work and sealed-system refrigerant repairs to a licensed HVAC technician. Enter your Payne model number to find the exact air filter, wall thermostat, wall thermostat, or other replacement part for your central air conditioner.
01 - Payne Central Air Conditioner Air Filter
Check and replace the air filter at least twice a year, more often in dusty/dirty environments or if there is a pet in the home. A clogged air filter will greatly reduce the air flow of the furnace or air handler which can result in poor temperature control when trying to heat or cool the home.

Highly Likely
02 - Payne Central Air Conditioner Wall Thermostat
The wall thermostat has electrical contacts that control the power supply to the furnace or air handler and condensing unit. If the contacts in the thermostat fail, certain components of the cooling system may not work or may only work intermittently. To determine if the thermostat is defective, use a multimeter to test it for continuity. If the wall thermostat does not show proper continuity, replace it.
Common
03 - Payne Central Air Conditioner Wifi Thermostat
The WiFi thermostat has electrical contacts that control the power supply to the furnace or air handler and condensing unit . If the contacts in the thermostat fail, certain components of the cooling system may not work or may only work intermittently. To determine if the thermostat is defective, use a multimeter to test it for continuity. If the WiFi thermostat does not show proper continuity, replace it.
Common
04 - Clogged Air Filter
If the air filter is clogged, air cannot flow properly through the home's venting system. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over and not be able to remove moisture from the air. The air filter should be checked and replaced at least twice a year, more often in dusty/dirty environments. Refer to owner's manual for guidance.
Less Common
05 - Blocked or leaking vents
The furnace or air handler must have good airflow to work properly. A blocked or leaking vent can prevent good air flow and cause inconsistent room temperatures.
Less Common
06 - Oversized air conditioner
An oversized furnace or air handler will quickly heat or cool the home and shut off. This causes acceptable temperatures in certain areas but not in others. The circulated air needs time to distribute evenly throughout the home; the air recirculating through the furnace or air handler for longer periods of time will produce better results.
