two part question

[green_apprentice]

I Read an article about defective compressor IN the rses journal. I know open windigs, bad valves, overheated and dirty condensers {overheat} can damage a compressor. undercharge and dirty condensers will cause the compressor to overheat, and trip on overload.if the overload contacts are close then you check the windings. over charge will flood the comp and damage the valves. my question is is there anythig else i forgot that will cause a comp to go bad. Second QUESTION what is an oem tempture control when replacing temp control for a rech in cooler.

Whaever was spec'd for that unit.

Electric supply to it, piping, incorrect procedures...
The list goes on and on. That's why it is important to understand what a piece of equipment is meant to do instead vs. what it is doing.

thanks, jerrycool and orlando for your response. anymore input fellows?

A unit demands power to be consistently delivered to it within ten percent of nameplate.

The unit does not respond well to on and off rapidly. It's called "short cycling". This will punish the windings and they will overheat and begin to flake off.

A unit wants dry and pure refrigerant inside it's sealed system.
Moisture helps to create acids and this will reak havoc to no end.
Copper plating and shorted motor windings will develope.

The return gas temperature to most compressors must be within 20 to 40 degrees. This is known as "Over-ALL SYSTEM SUPERHEAT".

If the temp of the return gas is too cold, it means there is liquid coming back and you have already posted you know that is death to the unit.

And when the return gas it too warm, the unit simply will NOT be receiving it's necessary cooling.
So it will operate hotter than it should.
The oil will begin to break down and lose it's ability to lubricate the bearings.



This is it in a nutshell. Hope it answers your questions.

Thanks r12 i knew i forgot something. moisture in a system is death to compressor. That why a good vacumm is important.

I think what he means is that almost everything will make the amperage raise and make the overload cut out.

#2 That is the cut in / cut out of the temperature control in the evaporator. 35 cut in, 15 cut out.

thanks..
