York model E2FH042S069A Heat Pump unit. Aprox 8 yrs old
At first-- giving error code 4 (discharge sensor problem) and shutting unit down until hard reset.
Replace sensor and wiring. Cleaned all contacts on board.
Now, giving error code 6 (same issue) but this code doesn't require a hard reset.
It seems to do it more late afternoon (hot and sun on that side of the house) and high humidity (over 60-65%)
Dealer is stumped. His recomendations are:
1) replace board (at $5-600 wi no guarentee problem will go away)
2) Repalce unit (aprox $1k) with new model that doesn't have all the #$%^& sensors.
