Repair Your Aircon at Home

ac_cap1              ac_cap2

When aircon at home fails, the problem could be just the capacitor.  A buzzing or humming sound is one sign that your capacitor needs replacement. I have experienced this with one aircon unit at home. So I removed the capacitor and noticed some bulging. A swollen or bulging capacitor implies that it has gone bad. After replacing the capacitor myself, the aircon worked again like new.

However, there are cases where you would not hear any sound at all. When you turn on the aircon, nothing happens. When you encounter this, most probably replacing the capacitor would still solve the problem.  Based on my experience with aircon problem at home, I tend to believe that it’s almost always a capacitor.  And you can do the repair yourself and save money.


Thankful for the Great Workplace

Work has always been a significant part of life. We’ve spent a lot of hours at work. So it’s important that we enjoy our life in the workplace. If we are not happy anymore with our work, I believe it’s time to think of our options and priorities. Life is so short to be wasted. As it has been said: “Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes.”- (James 4:14)

One of the things that I am thankful for in life is the chance to work in a great workplace at every stage in my career progression. I’m also glad to work with great people and learn from them. God has always been there to provide for the next career option when time comes for me to move on. So I’m really grateful for the companies I’ve worked for and God for the guidance in every career move. Thanks to colleagues, managers, professors, classmates, loved ones and friends who have become part of this life’s journey.


My Driving Experience

12/5/2017 (Tuesday)
Location: LISP2, Calamba City, Philippines

I was driving home from work and stopped at the LISP 2 (Science Park) intersection traffic light at around 5:40pm. It was already a bit dark and I was following a new white Toyota Innova with conduction sticker YV3647 and no plate number yet.

While waiting for the green light, the Innova in front of my car then backed away from the highway as it was already blocking the incoming truck entering LISP 2. As it came closer, I tried to honk continuously to get the attention of the driver but the Innova continued to back into my car and hit the side door. Then the green light appeared and Innova YV3647 just sped away as if nothing happened 😦 .

Grateful for the 5 Productive Years!

jeff_st_5yrsIt has been a little more than 5 years ago since I joined  STMicroelectronics, a European semiconductor and electronics company, after some time working with American multinational companies (Intel, Delta Design).

Well, I would say I enjoyed those first 5 years and they were productive years in my career journey. There were some challenges but more rewards to ignite a person like me to go on.  Indeed, time flies so fast if you are enjoying what you do. And I’m grateful to God for I believe He’s the reason of it all.  I’m also thankful to STMicroelectronics and all who have been part of my journey.

Working In A Tech Company

Working in a technology company as an engineer is challenging and it keeps me from getting bored. Doing routine job is the least that I like. Ever since I joined the semiconductor industry, I have been part of technology R&D doing some exciting design and development work. I find fulfillment in being able to contribute to solving mind-boggling technical problems.

There are a lot of opportunities in technology companies for people who love to think out of the box. For instance, if you have an innovative idea you can submit an invention disclosure and get some monetary reward when it’s accepted for patent filing and when the patent is issued or granted by the US Patent and Trademark Office (USPTO). Based on my experience, there would be frustrations along the way especially when what you think is a very brilliant idea/invention later turns out to be already existing or patented. But don’t give up. Sooner or later, you will come up with something that has not yet been out there.

And in all things, may God the giver of real wisdom be glorified. I believe all career achievements would amount to nothing without God.


What to do when your A/C is not blowing cold air?

There is definitely a problem when you observe that your car’s A/C is blowing warm air instead of cold air. It’s very frustrating especially during hot summer. One reason could be insufficient refrigerant due to some leakage.

But when you encounter this problem and you hear a very constrained hissing sound from the evaporator side (passenger side), then that’s a sign of a malfunctioning expansion valve. One effect also when you have malfunctioning expansion valve is that the engine idle speed drops significantly when the compressor motor kicks in.
