Maytag Central air conditioner not cooling properly
Is your Maytag central air conditioner not cooling properly or the air conditioner is blowing warm air? The main control board may be failing to send 24 volts to the condensing unit contactor or power to the furnace blower motor. This is not a common failure, so check other causes as well. An airflow problem is more likely: a clogged air filter or blower wheel can restrict airflow, cause the evaporator coil to freeze, and leave your home AC not cooling. Replace the air filter as recommended and keep registers clear. A defective contactor can prevent voltage from reaching the condensing unit, while a failed dual run capacitor can make the fan motor noisy, cause it to overheat, or keep it from running. If airflow is good, the coils are clean, and the blower, fan, and compressor run but the air conditioner is still not blowing cold air, a refrigerant leak or restriction in the sealed system may be responsible. A relay board can also stop the blower motor from receiving power. Enter your model number to find the exact replacement part for your Maytag central air conditioner. Turn off power before inspecting parts, and have a qualified technician handle 240-volt wiring and any refrigerant repair requiring EPA 608 certification.
01 - Maytag Central Air Conditioner Main Control Board
If the central air condensing unit contactor is not receiving 24 volts or power is not getting to the furnace blower motor, a possible cause is a defective furnace main control board. While this is not a common problem, if all other potentially faulty components are working properly, the main control board should be replaced.

Proper air flow is critical for the central air conditioner to work properly. The evaporator needs proper air flow to keep the condensing water from freezing. If the air filter or blower wheel gets clogged, ice can start forming on the evaporator coils, eventually freezing them up and preventing proper air flow. It is recommended to replace the air filter at least every 6 months or sooner depending on the conditions. Refer to owner's manual for guidance. Avoid covering registers with furniture, rugs, or other items that will restrict the air flow.

03 - Maytag Central Air Conditioner Contactor
The furnace control board sends a low voltage signal to the contactor. When the contactor receives the signal from the control board, it closes the circuit, sending voltage to the condensing unit components. If the contactor is defective, it will not provide voltage to the condensing unit. To determine if the contactor is at fault, use a multimeter to test the contactor for continuity. If the contactor does not have continuity, replace it.
04 - Maytag Central Air Conditioner Dual Run Capacitor
If the dual run capacitor is defective, the fan motor might be noisy, overheat, or not run at all. To determine if the dual run capacitor has failed, inspect the capacitor. If the dual run capacitor is bulging or leaking, replace it.
If the unit has good air flow, the evaporator and condensing unit coils are clean, the fan and compressor are running, and the furnace blower is on, but there is still not enough cooling, it is likely there is a leak or restriction in the sealed system. Since diagnosing and repairing a sealed system takes specialized tools and knowledge, a qualified service technician should diagnosis and repair the unit.
Highly Likely
06 - Maytag Central Air Conditioner Relay Board
A relay board is often used to control components of an a central air condidtioner. If the blower motor is not receiving power, the relay board is likely the cause. A defective relay board will need to be replaced.
