What it is
The fan on top of the outdoor unit that pulls air across the condenser coil. Without it the system overheats and shuts down on high pressure within minutes.
What you would notice
- The fan does not spin while the compressor hums
- The fan spins slowly, wobbles, or grinds
- The outdoor unit is far too hot to touch
- It cools for a few minutes then trips off
Can you do this yourself?
Pay a professional
High voltage, a heavy fan assembly, and a motor that has to be matched on voltage, rotation and mount. This is real work and worth paying for — but insist the capacitor is ruled out first, because the symptoms are nearly identical and the price is not.
What to say when you call
Red flags
- A motor replacement with no capacitor test documented
- A quote approaching replacement cost on a young system
The call-out alone runs $100–$250 before any work, plus $40–80/hr on top, evenings and weekends. A whole new system is $3,800–$7,500 — compare every quote to that.
