York Found out about the high limit for york tech service after unit fired up the bad thing was it was at a dunbar armored car sight with no windows talk about a customer having a fit then we proceeded to convince them that they needed to replace the unit
York
Code: York released no service letter that i know of well that would be way to simple for a big co to do. lol
York released no service letter that i know of
York Had a York start on fire on me last winter in heat start up mode unit running fine everything looked cool.contacted york and was told they had an issue with 6 ton and less with high limit not opening and catching unit on fire since then if you order new high limit it comes with aux limit and new harness York released no service letter that i know of
Must be a product de mexico.
This building was completed this spring I believe, possibly late last winter. I'm sure it's had some run time on it in the heating mode, but not too much, so this cold snap we had was likely one of the 1st. The company that installed it does good work and their service guys are pretty dang good too, so I doubt it was anything fouled up by a poor tech. Perhaps it was just one of those things. Kinda makes you realize how important our job can be though.

You coulda buffed that right out. Who was the last one to wrench on it?
do i see the disconnect is still on? If they want that unit re weird they better turn that off.
HVAC fire at our Cabella's this week... Not much damage done to the store other than some minor smoke and water. I have no inside info yet of what caused the fire other than the smoke got let out of something in the RTU. Looks to me like it started in the controls cabinet, maybe a faulty controller or a loose wire? FWIW it's a York unit, not sure what model though. Click here to see the picture of Mr Roasty
