Checking The Air Conditioner Capacitor, Air Conditioner Outdoor Fan and Air Conditioner Condenser Unit.
It’s important to share any information that we can provide when it comes to the DIY diagnostics of your central air system. A homeowner can save hundreds if not thousands of dollars in home improvements if done themselves. I found this little gem of a video on YouTube that is the first part in a series of videos that is a good example of a step-by-step process of diagnosing.
The air conditing repair technician goes over a few simple repairs that can save you hundreds of dollars if you are handy around the home.
Capacitor Repair: Not a lot to replace. Just take the wires off the old capacitor and place the wires on the new one.
Fan Motor Repair for the Condensing Unit: Most of the motors are universal in mounts and are versatile.
Here are some of the air conditioning repair basic steps the service technician reviews in the video.
- If the unit has been running turn it off for 2-hours and wait for the heat to dissipate.
- Remove the fuse block
- Turn the Thermostat on.
- Put the fuse block back in (prior to testing take the fuse block out as explained).
- When the unit starts running you should hear the compressor running and the outdoor fan unit. If one or the other does not run then you have an idea which part is not working. This is the diagnostic described in the video.
- If neither work then most likely the capacitor is faulty.
- If the condenser is running & fan not working, it will increase in noise as it reaches higher temperatures. If this is the case then you just need to replace the outdoor fan motor.
- If the fan is running but you do not hear the compressor running, after the fuse block is put back in, then most likely it’s the capacitor in need of replacement. Sixty percent of the time the problem with the unit is the capacitor or fan.
- If neither the outdoor fan motor or the compressor start then you will need to diagnose the power going to the capacitor. Is there power going to the capacitor?
- If you have no voltage then you will need to check the disconnect box.
