On new installs I only test @ about 200#. Looking for a leak, I creep it up to whatever it takes (never needed 600# though).

Straight cool systems 600# will exceed the rated pressure on the evap...

Brand spankin new $800k house.

Las Vegas has a serious shortage of skilled labor and inspectors.

I like the tile work. Murphy's law assures that the footprint will never match the next unit...

I'm trying to picture how a conventional water heater fit in there... unless they had to put the tankless in to accommodate the toilet.

Not sure which was more awkward. This setup, or me taking a photo in a public bathroom...

No cooling call. Bad OFM. Ok, lemme kill the power so I don't fry myself... Now where is that disconnect, Cmon!

I start looking around to see what else is Mickey Moused. Oh look there....

Cooling Current Input 6.5A

Compressor 6.6RLA
Condenser fan motor 0.85A

I am posting the solution to this thread in case anyone was curious, or in case someone searches this forum in the future due to the same problem.

It turns out that the variable speed module for...

I did not take any static pressures. I also have not resolved this problem yet. This is a vacation home and the owner is only out one weekend a month. I went out with Rundawgs’ guide (thanks again)...

Got the email. Thank you very much!!

The unit had the dual board setup. Apparently that arraignment is obsolete now and both boards were replaced with the single board configuration.

End of last summer we replaced the variable speed module on an ECM blower the motor because motor would not run. This resolved the problem and everything ran fine....

Fixing some coolers on an apartment roof the other day and I see a severed extension cord. Hmmm this is weird..., followed it to this connection. I considered plugging my radio in to the bootleg...

Sorry for the rookie question, but I have never been able to get a straight answer.

Went to a no heat call tonight. Thermostat was turned off but blower was still running, I take off panels and...

I particularly like the needless use of 90’s in the liquid line.

All that, and i'll bet all the customer needed was a run cap. hahaha

Wheel appeared fine. Straight. No vibration.

Yes. It is a GCS16. Sorry, typo. Anyhow yes the nameplate calls for a 3/4 hp motor. I removed a Century 3/4 hp 1075 3 speed motor rated for 4 amps. I don't know what was in it before that.

No cool call at a hair salon. Failure was the blower motor. Unit is a Lennox GCS18-060-75-4Y. Customer stated that she has been at this location for 3 years and has had to replace this motor every...

That dip in the condensate line serves as the trap.

Yup!

I took this picture while standing on a busy sidewalk! It must be safe though, green wire is only a ground right? pfft...

It may not have been internally insulated, but it is now.

That was the norm here for several years, 2 story's usually have piss poor access. Very scary some of the time. I have turned jobs down because of it.

I just bought a set of digital gauges. SMAN-4. I also got a set of hoses with the ball valve shut off. I have always carried two sets of analog gauges, one for r-22 and one for 410a. Both with low...

I appreciate all the responses. That gives we a lot to look at & consider. I understand how poor airflow would affect efficiency but could somebody explain how it would cause compressor failure?...

I had a call yesterday where a 2 year old 410a compressor was shorted to ground (Trane XB13). I checked it at the compressor terminals. It is a 5 ton split unit (cool only). I don’t have any history...

Came across this condenser the other day. Homeowner said he backed into it with a backhoe 9 years ago. Said he has never had 1 problem with it and it worked well. I was there to work on the other...

ahhh. that makes sense. Thx

I went to a no cool call yesterday. 5 ton ICP heat pump split unit. Owner said that nothing was running on the condensing unit so he hit the top of it with his fist and the fan began to run but not...

I'm not going to move it. But for my educational sake isn't the high side pressure the same between the compressor and the metering device +\- a couple psi?

So just cut the old one out and sweat in a Schrader valve for the Mars option? PITA for a simple valve. Thanks for the info though!

It is running like that. We have highs of 112 and lows at night are 95 so my options are limited. I like your suggestion of tapping into the service port for a temporary pressure switch and I will do...

Can anyone please explain to me exactly what a microfarad is and it's relationship to PSC motors and run caps in plain English. I know how to measure them on caps and match them to motors but that...

What problem did this cause that couldmt be covered by waranty?

Stopped for some Mexican food in San Diego. Looked up and saw this. For what it's worth the food was fricken delicious!

I need help determining the proper OFM & blade for 2 identical Lennox condensers (straight cool). I have a job at a bank repossessed house and someone stole both of the condensing fan motors and fan...

The cap looks like it woulda fit right back in the hole.

I just noticed that they are using white wires for the "hot legs". I suspect it doesn't really matter at that point...

Just had to get a picture of this. Owner thought it was funny that I found it "so interesting".353381

Yesterday I replaced a compressor on a 4 ton Trane heat pump (R22). Compressor had an open winding... anyway the change out went relatively smooth however I was only getting about a 10 degree split...

Rundawg that is twice you have bailed me out! Thank you sooooooooooo much!!!!!

Can anyone please come up with a schematic for a Trane BWC060D100JA. The sticker is loooooooong gone.

Thanks in advance!

Hahaha you funny. I was invited "through" the house to see about a possible job out back. I don't know how it is where you live but if I stop in the house and start putting my wrench on his equipment...

Walked through a house to access the backyard and came across this water heater. 2 draft hoods??? and that is electrical tape sealing the top of the flue pipe. I told the property owner we should...

Stopped for lunch and saw these apartments next door. Every condensate line is run into a sewer vent. No traps (not that it would help out here anyway).

Some more...
