Was told by some long time guy at the supply house to use dope not tape on pvc.

IIRC he claimed the teflon expands and can cause problems.

I've used blue monster several times and it worked...

I know a guy who did the same thing. He seems to like it alot.

He has filled out quite a bit too :grin2::whistle:

Correction, not 5 tons.

Maybe a 5hp condenser at the most.

Thanks again Terry.

She says "everything work good in winter. Always have problem in summer. AC never work good."

Oh yeah. After that the 10 door lineup, or whatever seemed to work better.

The indoor temperature dropped about 3 degrees after running most of the day.

There was about 12-14 of those...

I was at a convenience store checking out a few things and stumbled upon this maybe 5 ton reefer condenser in the basement.

I could not believe how hot it was down there. Then I saw the huge...

So are you saying I am a REAL refer man bc I can do all the above? :LOL:

I for one would have, but still thrown a wet rag over the valve quickly.

With a small map torch that would be heated up in 8-10 seconds and done.

Being able to braze it without choking...

Yeah nice unit too.

It seems 4000btu would be perfect.

I got a killer deal on a 12k. years ago.

Its oversized but it'll pull the room down in 15 minutes.

When there is company over and drinks/pool are...

I've never had much luck chasing down those oddball no-names.

I can't find the spec sheet either.

Could find a 1/8 hp compressor like a B60C5BL and see if it works.

I would agree with both assessments.

There is a broken tooth on the hub end that is jumping. At the closed position it may be relying on these to also hold it closed.

I would also imagine...

Water supply lines suggest the same, I happened to read the tag one day :whistle:

Going out on a limb but they do exist.

Surely the LLS is opening when energized correct?

Its not closing when energized and opening when de-energized surely.

Just to be certain also the coils use a single common LLS with a single...

When I think of 5/125, I think

a restriction, inadequate flow of refrigerant

Low on refrigerant

head pressure control

no evaporator fans running

Well my first guess was that, if the power is off and the solonoid is de-energized, then how are the pressures to equalize?

Through the head of the compressor?

That's too easy, something...

It did cross my mind.

I was going to post a very similar picture/suggestion, however, I thought an unloader kept the the suction from dropping during low load conditions.

I did not consider that although the pressure...

I believe the outlet of the gas valve operates in a negative pressure.

If the burner is SPOTLESS and clean, and there are no obstructions in the exchanger or venting,


Next thing I would...

This one tech I work with sometimes, always changing parts.

Those old ones we save afterwards, have rescued me in a pinch but I don't tell him that.

He doesn't have to pay for them, so its...

I wouldn't replace anything until you do more work.

Wouldn't you rather know what your doing than be a parts changer?

If it doesn't pan out I'm still counting it as my monthly good deed fyi. :)

Imagine putting all those parts in and having it do the same thing.

Have you checked all of your venting for blockages?

The burner, Well I should say flameholder(flame diffuser), pull that and...

Do you wait for the box to pull down and check/adjust the valve?

I know sometimes they come close out of the box. I typically like too see it between 10-12 degrees on coolers.

I pick it all off and put it back in the tub to re-use.

Nice work on the replacement valve.

Look at all those six pans and drawers/doors. That's a good size unit.

Those days are the worse.

I was diagnosing an electric sauna one day and forgot my new meter inside.

When i did retrieve it, it had softened up, deformed and was acting funky with a messed up...

Maybe a water inlet valve on one of those also. I remember not liking that little push fitting for the 1/4" poly water line on the inlet valve.

Dirty machines can cause alot of problems.

I can't tell you how many times someone will say " if you can just show me what to do then I wont have to bother you"

Read the book like I did. Who...

Not to say there isn't a problem, but wouldn't you agree that it is basically down to the factors that control when the unit cycles whether it be malfunction or misapplication?

And wouldn't you...

Do you even have to jump the thermostat?

I mean when it cycles off, just looking at the thermostat setpoint would tell you if that was the deal...

Place a K type from your meter or other test...

Or fiberglass insulation :p

Laying a small piece of heat sheild fabric over that hot exhaust pipe would be more practical than spending a few bucks on a fitting for something that hardly ever needs messing with.

Keeps your...

As far as access to the pressure tap goes, If you believe it is something you will using more in the future.

That is a 90...

:pop: Sounds easy enough.

Buy the bottem of the barrel, and use it for it's warranty period.

After the warranty period, if you are still planning to stay in buisness, plan on replacing it once the next total repair/parts...

Yes 1/8" MPT that was it. Glad you got it figured out. Its handy when you need it.

As far as what you were seeing with your pressures, take note that if this unit uses a digital controller, like the one that shows the snowflake when cooling and the little fan logo when the fans are...

Yes I have changed burnt out compressors just to start it up and watch the suction get pulled into a vacuum.

So anytime you do a compressor, should you change the captube also? It wouldn't hurt...

Sometimes a restriction is hard to deal with.

I have had units partially restricted that seem to cool fine but hardly provide any return cooling gas.

In other cases, I have seen additional...

Unless there were an issue with the existing charge, in that case your ahead of me. But more times than not, I will be ahead of you. I say its down to the filter and cap tube now.

The filter,...

I am pretty sure you are on the right track with this.

Being called out late in the day to look at this is a disadvantage on it own.

You came to a decent conclusion after you checked the fans....

I've serviced 101 of these units for the past 6-7 years.

Pulled every single one of them apart with my younger brother outside 4 at a time to clean the condensers.

The ID fan motors being...

Piping looks a lot better. More room in the basement now. Nice work.

Might be a cr3032 battery on the main board or sub board. If there is, remove it and measure the DC voltage.

Replace it if it measures under 3.0vdc. Remember the orientation when removing. It...

I believe it uses pressure. As the sump fills with water air is displaced causing a pressure increase.
