Maytag Central air conditioner has poor temperature control
If your Maytag central air conditioner has poor temperature control, starts with the air filter, the most likely cause. A clogged filter restricts airflow through the furnace or air handler, reduces cooling capacity, and can cause the evaporator coil to frost over. Replace the filter as needed, especially in dusty homes or homes with pets. Next, check the wall thermostat. Failed electrical contacts can make the air conditioner cycle improperly or operate intermittently, causing inaccurate temperatures, uneven cooling in the house, or an AC that is not holding temperature. Blocked, leaking, or poorly connected vents can also limit airflow and create hot or cold rooms. Finally, an oversized central air conditioner may cool too quickly and shut off before air circulates evenly. Enter your Maytag model number to find the exact replacement air filter, thermostat, or other part for your system. You can inspect filters and vents yourself, but thermostat testing involves electrical circuits, and repairs involving line voltage, the control board, or other energized components should be handled by a qualified HVAC technician.
01 - Maytag 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 - Maytag 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 - Maytag 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.
