Have you had your AC just stop working suddenly and usually after a thunderstorm? You say it was working fine yesterday and now the outdoor unit doesn’t operate/come on. The indoor unit works fine though, but no cold air. Hmmm, call a service guy! We need our AC!
|Your wires should not be burnt as above.|
Sound familiar? This happens quite a bit and usually after storms and occasionally for no explained reason.
What may have happened is the motor/compressor start assist device (sometimes called a capacitor) has failed. When the device that looks like a small silver can has had a power surge delivered to it; it has an internal short and fails to operate The top of the “can” looks like a “Jiffy Pop container that has popped up”. It has a noticeable bulge on top where the terminals are located. This device stores energy and helps the compressor and the fan motor start. When it fails, the motor and compressor may not have enough immediate power to start and will just hum. Over a short period of time; this can be harmful to the compressor and outdoor fan motor and cause them to overheat and fail permanently. Sometimes there is no visible damage and must be tested electrically by a professional HVAC technician or electrician. The capacitors can also weaken after time and become ineffective and need replacement.
These devices should last at least five years or more if they are a high quality part. Unfortunately, most of these devices (capacitors) that come from the manufacturers are of a low cost and quality variety and fail frequently.
What to do? If your HVAC professional tells you that the failed part is a motor starting device/capacitor, ask (if your technician does not suggest it) for an Amrad Turbo-200 device and or a surge protector. The Amard capacitors are more expensive, but are of a very high quality, are made in the
and have a 5-year replacement warranty. The surge protector adds another layer
of protection against the unwanted electrical surge that may do damage to any
of your electrical components within the outdoor unit.
A word of note: If you have an AC system that is less than 10 years old, check to see if you have a limited part warranty that will cover the part or a manufacturer’s part and labor warranty to cover the cost of the repair. If you just have the limited part warranty only, you will still be responsible for the dispatch, labor, acquisition, and processing fees associated with “free” part.
