High head on YCH180B3L0FA

Split and wash out the "inside condensor". Pull the top off where the condensor fans are located. Set the whole condensor fan assembly on the top of the unit. Thats why you have all that extra condensor fan wire! On the end of the condensor will be some screws that are holding the condensor in place. When you remove the screws there you will find maybe 2 or even 3 condensor coils that are zip tyed together at the return bends. Seperate the coils and wash them out. They are fairly flexible. Two men are required. After you find the dirt blanket on the inside take a picture of it and post it. Then everyone will know what stops a Trane.

Could be. I have had to do that before. Dang Tranes. If it aint that must be a restriction upstream of sight glass.

The question is are both condenser fans spinning in the same direction?
one may be spinning backwards, where it has a bad cap, or the fuse is blown (its the screw-on ones on the right side of the control panel).

If one of those fuses were blown neither of the fans would run.

split the flippin coils and quit messin around

Did you change the filter/drier? Did you look at the temp drop across the drier?

I've had pretty good luck with these RTU's usually fixes them when you clean the coils like you are saying. Actually kinda makes you think you accomplished something too.

Why do we think it is dirty coil or bad fan motor or bad blades?

He said he has 23 degrees subcool.

23 DEGREES SUBCOOL.

I don't get it. Maybe I miss something since it is trane unit.

your unit is under charged.Go by superheat for txv not subcool.

Idk...maybe that's how they do things up north..??

Hmmmm. I wonder how far North?

I recently took 182 lbs of extra refrigerant out of a chiller that was possibly charged to superheat. That was tripping on high head too?????

[tech93]

On a txv system superheat not subcool subcool for piston. should have 12degree superheat 10 to 11 sucbool . he system was converted to txv on a trane and said it was a single coil with means like 10 to 15 ton
