Trane XR-11 Outdoor Fan Coil Condenser Heatpump – HVAC Vibration Analysis
A Trane Model XR-11 heatpump with a metal fatigue (metal stress) problem in the center of the top grille. This is all due to the vibration and rotational torque from the fan starting. Vibration analysis is pending.
By appearances alone, it looks like someone stood on top of the unit, but that is not the case here. The metal has become torn in a nearly circular pattern. Hanging under the top support grille is the fan motor and fan blade. Once a small stress crack started, the repeated starting and stopping (torquing) of the fan motor caused a larger stress crack to grow (see center). Eventually the HVAC fan motor and fan blade fell down inside the unit and jammed from its own weight.
Its pretty old. Just do a search for Trane XR11.

This is the SAME …
This is the SAME model I have! Installed 9/04! 1375 sq ft single story home. It’s 5.5 years old. In that time, the capacitor has went out 250 dollars….the coolant tube developed a leak three months later…550 repair, and now the compressor went out 994 labor charge. Preventative maintenance was also done twice yearly. I’m re thinking the PM since it doesn’t seem to be helping.

What year was this unit made? I’ve heard of 10 and 12 SEER units, but I have never seen an 11 SEER.
