Kelvinator Central air conditioner has poor temperature control
When your Kelvinator central air conditioner has poor temperature control, the most likely cause is a clogged air filter restricting airflow through the furnace or air handler. Replace the filter as recommended, especially in a dusty home or one with pets. Next, check the wall thermostat. Failed electrical contacts can make the AC temperature inaccurate, cause temperature swings, or keep the system from holding temperature. Blocked or leaking vents can also create uneven cooling in the house by limiting airflow. A less common cause is an oversized air conditioner, which cools rooms too quickly and shuts off before conditioned air can distribute evenly. These checks can help with air conditioner poor temperature control, but thermostat testing involves electrical components, and repairs involving 240V wiring, the condensing unit, or the sealed refrigerant system should be handled by a qualified HVAC technician. Do not open the sealed system or handle refrigerant without EPA 608 certification. Enter your Kelvinator central air conditioner model number to find the exact replacement air filter, wall thermostat, wall thermostat, or other compatible part for your specific system.
01 - Kelvinator 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 - Kelvinator 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 - Kelvinator 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.
