SST is converted from suction pressure transducer.

Actually this is different than the original poster. But caught my attention since it went to my email. Carrier had a service bulletin and update for the "No Motor Current" and "Open Thermistor" ...

Thank you. I'll look for that next time. So far on the three I worked on it seemed it would continuously flash fast if it tripped while running and continuously flashed slow if it tripped before...

Carrier WSHP 50RHR:
Light on the board is constantly flashing green. I remove 24v and reapply. Light on board is now solid green. Blower and compressor runs. Supply air temperature rises to...

Plumbers & Pipfitters Local 421 has a training facility in Concord N.C.. North Carolina is underpaid. We gathered information showing how the surounding states have higher wages in our field and...

I wouldn't worry about the discharge supperheat too much. Just make sure the EXV is below 60%. The brine option includes solenoid valves in the liquid lines and depending on the size smaller...

I'd rather have a trap at the condenser or buy a brand that has a trap in the condenser than chance oil build up in the evaporator.

This is what I would think. I don't understand either.

This always puzzled me too! Working under a licenced company we could get any brand. If we want to buy for ourselves, we can't buy a name brand. They can only sell us a Payne, goodman or noname...

Not enough water volume. Need 4 to 6 gallons per ton. It's going into slow-change overide to prevent short cycling compressors and then getting stuck in a short-loop overide.

Yes it is. Still more for the pipfitters, but they are trying. We need members to make it better.

I like that.
I transfered to NC in 1998 when I thought they were merging the 638A and 638B. I lost my pension transfering from 638B Metal Trades to Local 421 Building Trades. Every time they give...

Thank you for the replies. I researched jungle boots and it lead me to search high heat boots. I ordered some form of high heat jungle combat boots. They arrived today and I look forward to using...

When I lived on Long Island buying a pair of boots with good thinsulate was expensive and hard to find. Now that I live in North Carolina where it's hot it seems finding a pair of boots without...

"HI-Tech" was a good company doing large commercial I worked for up there. They'll start you out brushing tubes, cleaning strainers, rebuilding cooling towers. I couldn't handle the drive living in...

I heard R438a will have a 7% efficiency reduction.

I did residential one winter. The company wasn't as open as that. I did notice I'd arrive early Monday morning and the bosses attitude was like "Well it's Monday" as people drifted in around...

Without the refrigerant moving through the screws the screws would heat up and expand into each other.

I had some maintenance guys at a college tell me one day that they had to reset that...

Figures...Our United Association Rep for Local 421 told us McQuay just signed on in another local during a meeting. Later I asked him the number and if I could transfer to it. He said yes. I...

Last month I heard from my United Association Local 421 that "McQuay" had just signed on with Local 275 in Miami Florida. I'm really hoping they sign on with us in the Carolinas. I'll jump in a...

I left long Island 14 years ago. I lived in suffolk county and could't take all that traffic. I say "Hi-Tech" was the best company I worked for. They do hire this time of year because they have a...

We have a card with "Cardinal Safety Rules" and other rules. Any personnel who fail to comply with the "Cardinal Safety Rules shall be subject to discipline as I am. However the rule I broke is not...

I'm getting suspended for stepping on the top step of a six foot ladder to get to the top two screws of a VAV box. OK, I'm in the wrong. I get that. But, to call me a Jackass and suspend me for...

I believe you are refering to the 30RA"P"
That setpoint was originally increased to 50%. As the prolem persist it was increased to 70%. However I found reducing the subcooling to work even better.

I thought it had to be a Telebyte 65A. I haven't tried yet. I'm only authorized to buy tools less than $100.00.

An expert contractor should be cheaper than that. It might cost more if he diagnoses the tubes to be dirty and has to return with cleaning equipment. However, having to call someone in after...

"Carrier, or one of their contractors, has been doing the compressor replacements."

This has been an issue for a while. In my area "Carrier" does the warranty now. There are a few machines...

Friday 3:00pm
Them: We need you to start this thing 1:00pm Saturday after we swap it out.
Us: Oil separators/Crankcase heaters energized for 24 hrs.
Them: Yeah sure
Us: Prestart Checklist...

Ditto!

You model number is incomplete. Is it 208vac?

Where did he find the leak?

Carrier just lost three guys. A service manager, a forman and a tech. Could be considered an oportunity or warning.

I agree. If the refrigerant has to come out to repair a leak then change the Danfoss garbage txv to a sporlan or alco.

However, I suspect even though a leak can be a cause, I'd bet the real...

If they are "Carrier" the actual name should be something like "Carrier Building Systems and Services or Carrier Commercial Systems". Carrier Enterprise dealers get to have the blue oval on the...

Ditto!

I see nothing that states where your located.

Need 2.4 gallons per minute per ton.

The last time we decided to keep the floor clean with a drain pan under a chiller we went to a sheet metal shop.

Yes, Especially with low load. Need to keep the refrigerant boiling off.

Now that I reread, mine was semi-hermetic.

I had a 120 ton Trane chiller under contract. It had two tan recip compressors. One tag said "Service First" the other said "brainerd". One tore up and the other circuit flooded. I pulled out the...

The carolinas are "Right to work" states so the unions are extremely weak. UA Local 421 is the union in the carolinas. CE Holt is the only big company I know of in this area that does...

$26.54 for Journeyman under the service contracts, Carrier, JCI and Siemens. McKinneys is under a mechanical contract, much lower around $20.00. However they are willing to pay more than $27.00 for...

"Yes, everyone has it. That really isn't my issue. There's alot more to it. " I've been doing this for 20 years now. Thirteen years ago I had enough of the four plus hour drives from central Long...

I just had to mention it because 94blowncobra is in Florida. I'd like to paint the picture without too many details on the internet. Yes, everyone has it. That really isn't my issue. There's alot...

Funny you should ask from Florida. The top guy from the Florida branch is now in control of the entire southeast and making alot of changes. He actually said the managers don't have to know...

I've been working for Carrier most of my career. The commpany has been going downhill since I started, but I've done well for myself doing startups and warranty. The last three years I feel like...

W=White

I like that rheem separated the mechanical parts outside the coil so I can work on them. I've had two Goodmans with bad reversing valves buried in the middle of the coil. Cheap part under warranty...

I have trouble with mine not defrosting as well. Some of my issue is self inflicted. This 13 seer unit I got free (another story). I hooked it up to my 1978 bryant AHU. I think I got it now. I...
