Red face Trane XR13 Condensor Fan Replacement

Trying to find replacement condenser fan motor for:
Trane XR13 4TTR3042D - 40,500 BTU - 3.5 Ton

Original OEM Condenser Fan Motor #'s are:
D157730P01 / Y7S859D02
Volts 200 1/6Hp
Volts 230 1/5Hp
RPM 850
Cap 7.5uf / 370vac

Current Capacitor is a Genteq 45 7.5uf Dual Capacitor Round / MFD 370 Volt # 27L947

Not able to find a OEM or replacement fan motor anywhere on line (Amazon, ebay, Grainger, google search) based on the original fan #'s above or even close to HP, RPM or Cap 7.5uf

Appreciate any information, suggestions or help, thank you!

Thank you for your help! Would any of those do, or must look for 1/6Hp, RPM 850, 7.5uf 370vac as original. And would it take same capacitor currently listed in above? Appreciate it!

Looks like must of those 1/6hp motors on Amazon show "Run Capacitor (uF/V): 5/370"

OEM capacitor (and a spare replacement I have) is 7.5uf / 370va

Any difference or?

The capacitor is matched to the motor. Doesn’t have to be an OEM rating. But the compressor side must match.

thank you roughneck77! "Compressor side" meaning the 370vac correct? So a 7.5uf / 370 vac capacitor (spare replacement) will be ok, work on a 1/6hp, 850 rpm motor with a cap listing of 5uf / 370 vac.

Thank you again!

Original condenser motor is fine, just looking for replacement information for future reference if needed

Compressor side only if it’s a duel cap. With a single cap it’s just matched to the motor.

Compressor side is the higher of the values..... like 35 or 40 uf.
The fan side is always the lower side.... like 5 or 7.5 uf.

Every motor has the size cap required on it. The cap size must match.

If a replacement fan motor doesn't match the dual cap...... just use the dual cap for the compressor and add a second one for the fan.
