Bad Oil Sensor Tripping York Air Cooled Chiller HVAC
HTML-код
- Опубликовано: 10 сен 2024
- Had circuit 1 oil sensor fail causing it to trip a safety lockout. York chillers are real common to have sensor failure but the oil sensor usually holds up pretty good. Recovery on air cooled chillers is usually a pain due to lack of low point to recover from.

You are an excellent teacher sir. It's much appreciative of how you share your knowledge
I couldn’t agree with you more about York adding a recovery valve,I changed a compressor on a yvaa and had to pull the liquid from the eductor line filter
Once you have the gas out. Solder in a few ball valves with flare ports. Also makes life easy when replacing the drier. Turns it into a 20 minute job.
Thanks for the videos!!!
Nice work!

Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses!
You can use a water hose gasket for that adapter works fine especially in a pinch
O-ring works just as well too.

Interesting job ... Thx for sharing ...
Excellent
According to sporlan you shouldn’t replace the gasket unless it’s damaged.
Maybe do soft shut down next time. Learn how to use system switches
often it's cheaper to get a whole valve assembly, just for the solenoid coil or the whole assembly may be all that was available. keep the valve as spare on truck or document and leave it inside the machine.
what mental genius designed the system so it needed a full recovery to change an oil temperature sensor? I guess they were too cheap to implement a brass or copper probe well.
When the stem leaks, and that’s common. There is a part number for a tube enclosure kit. Better than replacing a whole valve. Also locking your coils into place with a dab of silicone between the coil and the valve body will slow it down on rubbing and the stems will last 5-10 times longer.
What is the purpose of manually opening and closing drain and feed valve 0-100?
To calibrate manually, check operation, or recovery/evacuate
Need to get an old school reclaim machine. Those yellow jacket things are junk.my old reclaim machine is big and heavy but reclaims 4 times faster then the yellow junk with the undersized condenser.
its an Appion recovery unit and not Yellow Jacket, and the Appion goes good man ! Why the rush ? Getting paid by the hour 😁
@@stueyknuxx when you have to reclaim a freezer condenser on roof before crane shows up,job is quoted i not trying to play games i want that reclaimed as fast as possible.
@@richardharmon874 he wasn't recovering a freezer condenser before a crane though was he ;)
Hi sir how to troubleshoot chiller Hitachi always tripping
The only problem w nylok on the drier cap is good luck to the next guy during drier replacement. He will scrape and chip the gasket seat w his control screw driver during gaslet removal.
Been using Nylog for years and never once had it do that. You sure your not getting it confused with something else?
Been working on these machines for over 15 years and have never used Nylog on anything. Been working on chillers for 30. I can count on 1 hand how many caps have leaked after changing the cores. I do not ever use sealants on driers ever. Having a lid to seal up that it has to be broke loose is inherently dangerous.
Some BAS/EMS/ networking training would be cool 😎..

👍
Oil pressure should always be 5-7 lbs from discharge.
Why are you pulling the charge?. If
Your replacing the oil temp sensor. Close the iso valves and push the charge into the other side side of the valves. Takes 1 hr tops to get the gas out of that part of the circuit. Usually 20-30 min. Putting 2 days on for a oil temp sensor replace is way out of the norm.
You don't have an access port on the liquid line to do that on this one when the valve is front seated. There are ports on the discharge line but I choose not to pump liquid into the discharge side. This is a YCIV.
