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 USA,
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.
