Does anyone have the IOM for a York ycal0034 they can email me.
Thanks in advance
I'm sure they do. But unlike a lot of sellers on eBay they have warranties and accept returns.
I would probably shy away from getting one on eBay. Stick with companies like newegg, microcenter, and tiger direct. All have lots of options on new and refurbed laptops. If it's for in the field I...
I was told they are more susceptible to cracking. But he could have been full of it.

I like that they used 45s. I was taught to never use 45s.
I'll have to check hvac pro to remember if it can be setup for 10k. I don't think so but I've been wrong before. I just always use 1k nickel on jci controllers w a few exceptions.
A unt would see 10k ohms as open and read 250.
That's the problem. Wrong sensor. Need a 1k nickle
Put a jumper from ai1 to ai common and look to see if reading changes
It could be programmed to any of the inputs. You would have to upload the unt with hvac pro to look at it or change the analog input
You can move it say from analog input 1 to 2 but you will have to change the programming in the unt and front end to see it. Try hooking the sensor directly to the correct input without any wiring...
Does anyone have the service manual for a Ruud uarl-048jec. My neighbor is having some problems after a storm and the unit is giving a "high line voltage" diagnostic code. I'm measuring 245vac at the...
He's right and your wrong.
Carrier model numbers work like this
48tjd004 =3ton
005=4ton
006=5ton

What are the temps inside. Return air db, wb and supply
Use hoses and sight glass.
All the goodman manufacturing facilities I see in Houston have had their signs replaced with Daikin signage.
My neighbor wanted me to look at his system and see why it doesn't cool well in summer. So I go over and look at duct work first.. Get my maagnahelic out and start checking, the TESP was 2.6" ...
Had that happen before. Ended up replacing a bunch of motors and compressors and installing phase monitors.
At least he's working under a license. Better than a unlicensed hack in a nice truck.
A customer was cleaning out their work shop and gave me a bunch of hvac tools they don't use anymore. They don't have an in house tech anymore. One of the things they gave me was a almost new thermal...
Yes you can. But why would you want to?
600's are 460 3 phase
500's are 230 3 phase
300's are 230 single phase
100'S are 575 3 phase
We always have our customers use Firefox. We've had too many problems with Internet explorer not working.
We have had at least a dozen customers call for the same thing in the past week. We deleted java and manually installed older version.
I'll write it up again. Doubt customer is gonna pay to pull the charge just to see how much is in there.
It's one of two units cooling the space.
Blower is direct drive. Currently on low speed. No change on med or high. I agree on the amps hence why I posted it. If the amps were low along with the other readings, problem with the comp would be...
I'm leaning towards inefficient compressor because on cooler days unit looks great and on warmer days it does this. I've kept an eye on this unit for a couple of years and it always does this in...
No one is complaining. Found it doing pm
Fixed metering device. No txv. Return air is at 50%rh. I was thinking wrong size piston maybe or compressor not working properly.
Have a York d4ce060a25a
86# suction with 4 degrees sh
200# head with 96 degree liquid line
Comp amps 12.2 11.3 12.1. Rla is 16
Return db 75. Supply db 63
Unit has scroll compressor. Coils clean...
Installed an amana 3 ton system for the in-laws back in march. No problems until now. Father in law calls and says the secondary drain pan is full and unit is off on water gard. Go over and clean the...
I get my veto stuff here

Try calling them. They have always been helpful and can tell you if it's available or when it will be.
The set with the bad LCD was dropped. The board that went bad was from static discharge I think, and I'm not sure why the two valves started leaking. I'm pretty hard on my tools overall. And no I...
So I finally sent them in last week and received a quote today. $70 dollars to replace the lcd display in one set and $61 to replace the body w/ hook and both valves in the other. They are replacing...

This is a pretty good one. I'll have to see if I have a .pdf of it.
So now both of my 550's are having problems. First one- high and low side valves leak by, and it doesn't see the temp clamps any more. Second one- The screen is out, and the hook is broken. I have...
Dispose of it properly by dumping it down a sink drain or storm drain. Just kidding. My company has a large container at our shop that goes to an oil recycler.
I pressure check with 200psi of nitrogen. Then I check all the joints with snoop or other liquid leak detector. Do a standing pressure check for 30 min to 1 hour (overnight if possible). If there is...
Just wondering if it's ok to have a crankcase heater that's always on. Ideally I like to have it on when the compressor is off and have it off when the comp is running. But the system I'm working on...
i have a Supco DDM55. http://www.supco.com/images/pdfproductsheets/DDM55.pdf
That's the stupidest thing I've ever seen. Why didn't they put them on the ground and run duct work up outside of wall?

Get one of these. Works great
We'll take the humidity back if you send some rain with it!!
Today was the first really hot day for me. It's hard to imagine that last summer it was already 100 here.
Define residential.
hope this helps. Diagram is on page 16 I think

There air to water heat pumps out there but finding one that big may be hard. Probably better going with a new boiler and chiller.

The Clean Air Act does not allow any refrigerant to be vented into the atmosphere during installation, service, or retirement of equipment. Therefore, R-22 must be...
