Nordyne Central air conditioner has poor temperature control
When your Nordyne central air conditioner has poor temperature control, uneven cooling in the house, or ac temperature swings, start with the air filter. A clogged filter is the most likely cause because it restricts airflow through the furnace or air handler, reduces cooling capacity, and can frost the evaporator coil. Replace the filter as recommended, usually at least twice a year and more often with pets, dust, or construction nearby. Next, check for blocked, closed, or leaking supply and return vents that can create weak or uneven airflow. A wall thermostat with faulty electrical contacts can also cause the system to cycle incorrectly or fail to maintain the set temperature. Test thermostat continuity with a multimeter and replace the thermostat if it fails. An oversized Nordyne air conditioner may cool quickly and shut off before air circulates evenly, causing the AC not to hold temperature. Enter your model number to find the exact air filter, thermostat, blower wheel, or other replacement part for your central air conditioner. Turn off power before servicing; 240V components require qualified help, and any refrigerant or sealed-system repair must be performed by an EPA 608-certified HVAC technician.
01 - Nordyne 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 - Nordyne 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 - Nordyne 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.
