Why Won’t My AC Unit Turn On?
The last thing you want to deal with on a blistering hot summer day is to turn on your AC unit only to find out that that it won’t start up.
But why won’t your AC unit turn on? Fact is, there could be several reasons why your AC unit is failing to start up. Let’s walk you through a few of the most common culprits. And as always, when in doubt, call a professional like Page One Air to get your system back to working like new, quickly, reliably and affordably.
Your Electrical Panel: Depending on the age of your home, this could be either a circuit panel or fuse box. A “blown” fuse or “tripped” circuit is often a simple and easily fixable reason why your AC unit refuses to turn on. In the event of a blown fuse, simply replace it. With a tripped circuit, simply flip it back to the “on” position and try again.
Shutoff Box Fuse: Some AC units may have their own fuse at the shutoff box. This may need to be replaced if blown.
PRO TIP: If following the steps above fixes the issue but you keep blowing fuses or tripping your circuit, please call or message us immediately. This may mean that your AC Unit is pulling too much power.
Shut off Switches: Many AC units have a shut-off outside the box. Check to see if it has been switched to “off”. You may also have a switch near to your furnace or HVAC system that turns the power to it on/off.
Clogged Drain Lines: Some units have emergency auto-shutoff triggers if the drain line becomes clogged.
