Electrical question N/T

Mike, you hit the proverbial nail right on the head.

Okay now that we are all on the same page with indoor evaporators and or air handlers with same. Allow me to muddy the water again; modern HVAC equipment and other types of commercial/industrial equipment often utilize what is commonly referenced or known as a HEAT PUMP circuit.

A heat pump is essentially a refrigeration circuit designed to operate in reverse or in simple terms by reversing the refrigerant flow… So in heating or heat pump mode, the evaporator and condenser switch roles or reverse, hot indoors and cold outdoors. Kinda like reverse technology, albeit there is more to it than that.

Dan, them young bucks are from another world, what happened ever to common sense, honor and respect for yer elders! For some mundane reason they have little to no interest in old guys sharing their wealth of knowledge garnered by years of experience. I enjoy “learning” my guys how to diagnose/repair machines and or equipment, problem is most of em don’t seem to have much or any interest in understanding how things work. Instant gratification reaped of changing out parts seems to be held in higher esteem than figuring out the how, why and when things work properly or not.

Yup, and its in the copier industry too.

Ustabee, sailors could repair their gear, right down to micro-miniature repair of electronic cards. Now, they just switch out the card. Granted, switching out the card males sense while the bullets are flying, but that is rare, even during wartime.

OK guys, since you started this “Household Appliance Repair Forum”, I have several questions.

Is it wise to try using several GE electric steam irons that have never been used since my wife left me back in 1973 ?

How about repairing an old Sunbeam Electric mixer…of the same era ? I might think about mixing up "Cup Cakes/ala Marconi Style, for the Saturday morning operators, in one of my weaker moments…!!

I also have two old Radio Shack AM/FM radios era 1985, that seem to go off frequency very often…bouncing them lightly on the floor often helps…are they worth fixing ?

…then there is this old vibrator I found in an old drawer…

Fr.Fred

I suggest you repair the vibrator first, happy wife happy life.

Greg

His wife left him, remember?

That’s what happens when you take too long to repair the vibrator. (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)

Thanks Greg, I thought as much. I just think he ordered too large of a unit four the space he has.

He could always open a door or window introducing outside ambient air temp and dew points

I ain’t touching the vibrator comment because Greg would rather discuss trains as he has stated many times in the past.

Besides it probably doesn’t even have the proper ditch lites and HEP cabling if it was made in the 1970’s

I thought it was time for a little levity… I hope my joking did not po Fred.

It was mentioned that no one repairs anything any more. Just throw it out and get a new one. First, let me say that we can thank ourselves for allowing Chinese cheap labor to make stuff. Secondly, if we don’t learn how things operate, we are going down the path of dumbness. There are two things that propagate the dumbness syndrome. First is what I mentioned above. Second is liability issues. And of late, the latter seems to be overpowering the former.

If the above is too political, may the moderators strike it from the record. But I’ll still believe it. LOL

Plug and play and throw away.

Precisely !! But it leaves us vulnerable to being lost in the desert, so to speak. When I first entered the carpentry trade, I had to think. As I was retiring, it seemed that everything was a system, leaving the tradesman to just put it together accruing to an instruction sheet.

Dan, don’t despair. Those that learn how to make and repair things still exist (my youngest is one) and that makes them more valuable in the workplace.

John, I wish my boss saw it that way. But, I am still in a repair industry. Its just that us seasoned techs know more about how the machines work, then the new kids, who are just parts changers.
