How to diagnose common KitchenAid central air conditioner problems

Here are some central air conditioner problems you might run into, and what to do about them.

• Won’t turn on. Check the house circuit breaker for the central air conditioner to make sure it’s turned on. Reset the circuit breaker if it’s tripped. Low air flow can also prevent the central air conditioner from working, so check the air filter and replace the filter if It’s clogged with lint. Check for a clogged evaporator condensate drain pipe because a drain clog can cause the central air conditioner to shut off.
• Lack of air flow through the vents. A clogged air filter can prevent air from flowing through the vents, so replace the air filter if it’s clogged. If the filter isn’t clogged, a problem with the blower fan may be causing low air flow through the vents.
• Makes lots of noise. Bearings in the blower fan can make loud squealing or screeching noise when the central air conditioner runs. Replace the blower fan if its bearings make noise while the fan runs.

Clearing a clogged condensate drain line in your KitchenAid central air conditioner

• Shut off the house circuit breakers for your central air conditioner to disconnect electrical power.
• Pull the float switch out and vacuum water from the condensate drain system through the float switch hole.
• Use a plumber's snake to clear the drain line to the outside of your home.
• Pour water through the drain line to make sure it's clear.
• Reinstall the float switch and restore power to the air conditioner.
• Pour one cup of liquid bleach through the drain line every six months to keep the drain line clear of algae.
