They have to minimize the cost. 

My cynical mind suggests that they make much more profit  supplying replacement boards..or total replacement systems  

IE:  built in obsolescence. (via proxy gecko and ant attack )

In the latest aircon adverts they advertise as a feature "anti geckos"

I wonder (only very slightly) why they don't "pot" their circuit boards

(pot is to encase in a waterproof resin as found on many automotive components)

I've found Geckos only get inside the indoor unit not Outside.

This causes a problem with heat dissipation.

 

I would say a well designed board should have minimal heat and if unavoidable then  provide a heat sink  exposed from the potted board

again  I suspect that there are many built in failures and obsolescence's

What do you think the margin on the boards are? I've been here for about 25 years, I have seven AC units now, and I've never had to have a board replaced. 

 

My three Carriers are 5-year 100%. 10-year compressor. What do you think a service call costs Carrier? 

 

It's also a repeat customer issue. 

 

I think "planned obsolescence" is about making people want the new model, not building a POC that goes south two weeks after the warranty expires. 

 

If I had to replace and expensive board a couple times, I'm done with that brand.

The Geckos get inside the cat, but end up outside at some point...

I've never had one in mine   "but never say never"  

I suppose they can crawl up the evaporation water outlet  and find their way indoors like the cockroaches     I put  a U bend  in my water outlet  and think it works to prevent insects/geckos  but maybe  promotes a bit more of the slimy goop that causes the pipe to block up and flood the bedroom at dead of night

I also have a drip pan under the air con to catch any  condensation leaks in the dead of night.

Oh and I'll tell you another thing, my ceiling fan that has not worked for years, now works on low speed ??

I have 2 that live somehow behind the indoor unit, I have a hose fitted to the drain pipe outside, and when in the past I've had water dripping inside,  I have filled my lungs and blown into it, out came a slimy dead 'gecko'. You should not be getting any leaks at all, that would indicate your drain pipe is blocked, or the inside 'condenser' needs cleaning.

At the very least the ground/earth ( and probably Neutral) potentials were elevated as the earth absorbed the 30-60,000 amps of current nearby. Computer controller boards and their power supplies usually have very limited resistance to an elevated earth voltage. Solid state inverter units are another example.  A surge protector on the power input to the device can help. Lots of possibilities with a close strike. If some of the current passed along over the outer surface of the building, then all bets are off , particularly anything on the balcony. And you do get a magnetic field effect from that amount of current nearby. Structural steel can be magnetized by a hit and cause deflection of a compass when held close by. You can get similar effect from an arc welder, or so i am told 😉.

 

So what did the techs find ?

I think you are spot on with your comments, about a year ago a tree directly outside our house was struck by lightening, this resulted in the power board and some other component in one of our two washing machines being rendered useless.

The laundry is outside and about twenty metres away from the tree neither were in use but both plugged in.

Not to nitpick, but the inside condenser is called the evaporator.

Wouldn't a surge protector prevent such situations from lightning or voltage surges on home appliances ?

Not if the spike comes through the ground, I think.

Which is why maybe IMHO, if I may, it could be a good idea to get the unit cleaned by the Somchai's, at least once a year ?

Getting the unit cleaned is a good idea for efficiency/ electricity cost,

ants, geckos,cockroaches  don't really care..they just seem to like the EM fields.

Agree 100 % you should not be getting any leaks but T.I.T

I have done the full lung blow  and thought it worked but didn't

better is a full lung pressure washer blow for quite a while..the slime/mould that grows in the evaporator  water pipe is quite resilient  dead gecko,cockroach and ants included.
