By troubleshooting a broken air conditioner yourself, you may save a lot of time and money. When the air conditioner stops working, your first thought may be to call a professional for repairs. While repairs may eventually be necessary, try a few simple things first. These tips might help you fix the problem:
If your thermostat is not measuring temperature correctly, it might not tell your air conditioner to turn on. Dust might be interfering with the mechanical switches, or there could be faulty wiring inside the thermostat. If it's the mechanical switches, some light dusting might fix the problem. If it's the wiring, you should contact a professional to properly and safely handle the issue.
If the air conditioner won't come on at all, it's possible a fuse blew. This can happen inside the air handler, inside the condenser unit or in your fuse box. By replacing this fuse, you can easily get things up and running again. However, if the air conditioner quickly shuts down because another fuse blows or trips, there is a deeper problem that will require a look by an HVAC professional.
Don't forget, if you're going to replace a fuse in your HVAC system, turn the power off first!
Sometimes leaves, sticks and other outdoor debris can get inside your condenser unit's fan and clog things up. This may result in fan blades unable to spin, but it can also mean the air conditioner won't cool as well as it should. If you can easily pull out branches and sticks from the condenser unit, you should. Shut off power to the condenser unit first. Under no circumstances should you stick your fingers through the grill or try disassembling the condenser unit yourself.
