Burnout clogged evaporator

[krazytech]

Has anyone used MAINSTREAM QWIK SYSTEM FLUSH® to clean out a burnout compressor?

Compressor has been replaced But and there was alot of green / black sludge in the system..that sludge keeps plugging up the evaporator..

the qwik system should clean the system out... has anyone use this stuff and what was your method of use?

I have heard of R-11 but have never used it....

A local HVAC tech swears by the Rx11, sounds like the same stuff, but I've never heard of the other system.

I use R-11 flush. It works.
Cut your lines loose.
Inject R-11.
Attach your nitrogen tank and blow it through the system.
Use a clean rag to catch the gunk coming out.

Can you blow it thru a cap tube? and dryer?

This unit has a leak (low on gas) another tech when out and added gas 2 weeks later. The compressor had a burn out ... Could that tech have over charged it so much to blow all the gas out...  the evaporator had and still has a bunch of crap in it....

Yes,a severe overcharge could cause a problem.
From what I am reading I am leaning towards a restriction that blew out when he charged it and sent sludge through the system.

Sorry about the delay in responding.
My ISP was down since Sunday a.m.

This tech that burned out this compressor charged it by pressure, he did not use a charging cylinder... So he really did not know how much gas he was putting into the system...
