4 wire heat pump fan issue

[Waynejo]

Replacing old thermostat with new Nest 2020. 4 wire system, Rheem heat pump. Working system but when I installed the nest the blower dan would not function. I used the G wire as a common, compressor came on but no fan?? Reinstalled old thermostat, works fine.

Post a picture of the original thermostat's wiring.

If you don't have a C wire, then use the Google Nest Power Connector. The G wire trick never works correctly and you lose fan control.
