Air Conditioner Repair For Dallas Homeowners

It is a hot and humid day. Your clothes feel like they are sticking to your skin, yet it is supposed to be cool inside with the AC on. It seems like there is something wrong with your AC unit. Air conditioner problems are common, especially after a long summer. Sometimes, there are things homeowners can do to get their system operating again without spending a fortune on air conditioner repair fees.

This video explores the two most common HVAC failures. Those being the run or “Dual” capacitor and the outdoor / condenser fan motor. How to diagnose and replace these components with new parts.


DIY Air Conditioner Repair

Step1: Shut off the power

Open the electrical box next to the condensing unit and pull the disconnect block straight out. Check the box with a voltage sniffer to make sure the power is really off.If the condenser coils are clogged, the compressor can overheat and shut down. You’ll experience intermittent periods of minimal cooling, followed by no cooling.

Step2: Check the fuses in the disconnect block

Set your multimeter to the lowest Ohms scale and touch the red and black leads to opposite ends of each fuse. If you get a numerical reading, the fuse is good. But a zero, a minus symbol or an infinity symbol (∞) indicates a blown fuse.Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs

Step3: Discharging a dual start/run capacitor

Remove the capacitor from the retaining bracket. Then touch an insulated screwdriver between the HERM (or “H”) terminal and the COMMON (or “C”) terminal. Do the same between the FAN (or “F”) terminal and the “C” terminal. On single-mode capacitors, just make a short between the two terminals.

Step4: Install the new capacitor

Slide the new capacitor into the retaining bracket and tighten the bracket screw. Secure the wires with a zip tie.Capacitors can degrade slowly, providing less startup power over time. Or they can fail in an instant. Gradual capacitor failure can go unnoticed for a long time, stressing the compressor and condenser fan motor windings, resulting in their early failure. Since capacitors are cheap, it pays to proactively replace yours about every five years.

Step5: Swap out the contractor

Yank a connector off the old contractor and move it to the same location on the new part. Tighten the connectors where needed. Then secure the new contractor in the condensing unit. Unscrew the old contractor before removing the wires.

Step6: Replace the fan motor

Mark the blade to show which side is up. Loosen the fan blade set screw and carefully pull it off the motor shaft. Then swap in the new motor. Route the motor wires through the old conduit and secure with zipping ties where necessary. Don’t skip the zip ties or the blade could cut the wires.
