look at criteria for fault, most likely the IGBT on 'a' is faulty from being overheated

replacing just the gate driver board is not...

you should be able to pick the one best for your application

good ya caught it

just in case it wasnt mentioned

better check nozzle orifice size, r-22 is smaller than 404 and 507

whats the pay?

ouch

if you doubled that, that might help with cost of living there

you stated you need "top gun"

yet post wage range from apprentice to not so much "top gun"

you are not in a unique position, having to find 'top gun' mechanics.......

where i am at, large...

yea, my local said they have had some with travel cards go there with little to no issue

might just look into that

you have a link to the company in question?

what do mean by hotter?

oh I thought you knew it was wrong, and when you installed the new one, you corrected and tested it.

sorry

I think you need to stick to just the facts you have in front of you, and convey to copeland, I am sure there will be no issue in warranty


-you found what could easily be the cause of the...

forgot to washer down the liners,,,,,,,,,sounds minty fun!!

I was called to do start up on a new 5H80, I get there, and see 3 dead ones hidden in the corner of the room!!!

I asked whats up...

I kinka figured it was real low.

And I totally agree, one is not doing their job fully if they dont fill out a start up log, I have done my best trying to instill this step to apprentices that...

copeland offers a 2 year warranty if you fill out their startup sheets

you have to ask for them

if you get nowhere with this guy, phone corporate

unless they have done a 180 recently, that i...

copeland's policy is

1 free replacement regardless of the screwup

It is to my, and bitzer rep i deal with, great displeasure they do that, but that is a fact.

BItzer now does the same

and must have never ran out of oil

until it did.

if both control wires were connected to L

you removed the SAFETY

L and M is the switch that OPENS and de energizes the contactor.


now you know why the compressor had no oil in it and...

Inspect the contactor contacts.

do they still look new?

then you have to use your own judgment

if it has no UL markings, who knows

its an appliance

is there a UL marking on the data plate?

thank you

what is top hourly rate you are willing to pay?

sized bigger.

that is copeland recom

UL, the governing body say 1.56 is acceptable

i had this talk, many years ago with bitzer and copeland engineers as i said before

UL relaxed its standards, and also...

copy and paste from bitzer

"Technical Data

(6G-30.2Y)
Technical Data
Displacement (1450 RPM 50Hz) 126,8 m³/h
Displacement (1750 RPM 60Hz) 153,0 m³/h

Also if i remember

contactor is 1.56

conductor is 1.4

I talked with both engineers at emerson and bitzer on this

they both mean the same thing, they told me, just different convention for authorities they serve, europe or North america

as long as...

I suggest you get the MOC by contacting the manuf via internet

this is how you size your relay/contactor/motor starter or even VFD


there is NO OTHER WAY, this is the industry standard by the compressor manuf to meet UL requirements


you go to the manuf...

the fan will be fine

used them on many applications, just find the right capacitor is the thing

fan motor cycling is far worse than variable speed for the motor, IMHO

its an option, whom ever bought it, opted out

and chose fancycling instead

you should have chose a P66. variable speed controller instead IMHO

"I didn't grab the suction temp at the comp but felt like only about 65*F, not very cool."

you have a -20SST at evap with 8F superheat, and the pipe temp at compressor is near 65?

are you sure...

how many defrosts has the unit gone through?

you have 19 TD, sounds like the coil is frozen over

dont limit yourself

expand your imagination!!

TWIN screw:cheers:

have a couple of those on ferries

1 Tech from cimco

and

2 facility untrained persons

none were wearing their Respirator

What about US "R" people???

Merry Christmas !

okay

how many hours did you spend in total on this repair?

How many billable hours in total for this repair?

i think that is operating signal

design pressures, i like burst, are way higher

I have not heard that anywhere, talking with engineers at emerson or alike............


here is a little spec sheet
