Call it emerson and put in the "liebert "part. There aren't enough that fail to abandon the oem part. How fast can emerson flush this brand ?
I just had yet another failure - leaks in around the bellows, LPCO this time, and the loss of 100+lbs of 22.
This is approximately 2000' vintage DS units. The last time this came up -a year ago, we had two leakers and checked them all, and ended up replacing four at the time.
I'm considering replacement with something like the Mars module type;

I don't recall seeing one of these ever leak or fail.
Down sides?
May not be wide enough C/O - C/I?
What'd ya think?

I've found a few p66 fan cycling switches leaking on remote condensers. The lpc and p66 are the first 2 things I check when leak searching.
Chaos equals cash$$$
Liebert rep says more or less, the same thing is in the P66 ('wiper instead of a two-position sw of course- I've only seen a few leaks there) and, he sells about ten a month (the LP/HPCO's) - i.e. like they're some kind of a 'wear part.. Lets see, oh yeah with hundreds of lbs of refrigerant at stake.
Ok How about we start here..
Anyone ever see one of these little module type switches fail/leak?

We have had 3 XD systems blow their charge due to the cap tube type pressure switches. Vibrations snapped cap tubes loosing 240lbs r407c.
It happens. If people did their job on PMs, it probably could be prevented.

I agree about pm's. We catch a lot of bellows failures on pm's. Usually before it even causes a noticeable change in the charge.
This unit (R-22 BTW) was healthy about a month ago when I was on it last.
I don't think it's 407c causing the problem. Has the same pressures as 22.

And the same failures with R22. Oil and refrigerant type so far seem to be irrelevant.
I would agree

Huh, that is a bit interesting. It seems I've changed out half a dozen dual pressure switches over the last three or four months. On 404a systems. All due to the bellows. Used to be you'd virtually never see a bellows failure. Maybe the stuff is being made in China instead of good ol' US of A.
Ive changed a bunch of p66 controls leaking in the bellows.

Anyone pm'ing lieberts without swiping the cap tubes with fingers to check for a blown bellows is not covering their bases. Of course, looking for abrasion points on cap tubes is also important, but between the p66 and the two inside the unit, there's no shortage of work over time.
