Air conditioner fans not working can be a sign of a frozen evaporator coil. The relay board provides voltage to many components of the air conditioner including the fan motor. Relay boards are often misdiagnosed. Shut off the power supply to the air conditioner at the disconnect or breaker panel.

Remove the service panel on the a c unit. Most ac systems are designed to work within a large range of temperature variants and environments however due to numerous causes the air conditioner is still prone to overheating. This is another part that must be repaired by a professional hvac contractor. The evaporator coil sits inside your home within the air handler unit furnace or fan coil pulling heat and humidity from indoor air as it passes through.

It s located on the side of the building near the outdoor a c unit. An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor. Another common problem with the air conditioner blower motor not starting up is caused by overheating. Do not touch the capacitor terminals or you may get shocked.

Do not proceed if you re not sure you ve properly shut off the power. It is common for the contactor to go bad over time which restricts the outside fan from working properly. If your ac system turns on but doesn t blow out cold air ensure all the vents are open and the thermostat is set properly. If it s clogged with dirt or other debris you won t get any air flow.
