a/c problem everythings running but need help

[Jickracer007]

Stupid question but were you the first person there?
I live in New Jersey and have been going on call-backs from other companies and much to my dismay I have had to remove all refrigerant and TXV if applicable I am starting to really believe guys are putting the wrong refrigerants in.
I have been on two in this past week.
Sucks for the customer but when I leave the systems are running beautifully
They seem to be adding very minimal amounts but thats all it takes

changed filter drier and weigh charge in still same problem any ideas?

[Brad gall]

ive already put new 22 in but my pressures continue to fluctuate like theres non condesables. not sur what else would cause this

[shaka]

Brad.
Are you reusing same refrigerant from original problem
Or you change it out after u pressurize it with nitrogen

[shaka]

What's ur pressures this time

[Brad gall]

new 22 I charged by weight and pressure the same as the first day I was there 85suc 350liq both fluctuating @70/85 315/350

[shaka]

How much did u weigh in and what does name plate say?

[Brad gall]

64oz and the lineset was @20ft

[shaka]

It's almost acting like u don't have enough condenser at 350 psi.
This is what I would check for

Check to see how many circuit the condenser has?
Remove condenser fan panel
Run it with out condenser motor
You need to feel each circuit
Make sure they are all hot
Just to make sure no circuit is plug

It's not in ur liquid line cause ur high side would be lower

[Brad gall]

would it make the pressures fluctuate if the fan blade was bent . because the homeowner vacumed out the leaves he said and I was thinking maybe its not rejecting the heat but I dont know if that would fluctuate the pressures .thanks again

[shaka]

Brad u said this all started after a bad capacitor
By any chance the condenser is going the wrong way?
If wires are put in wrong on a 3 wire to run cap
It will reverse rotation.

[shaka]

I can see head pressures that high and fluctuating if it's going the wrong way.

[Brad gall]

rotation correct . I was thinking probably running hot with those pressures popped the capacitor to start with.
