Received an urgent request from a grocery outlet in Fontana, California. Their upstairs AC was kicking on in heat when it should've been cooling. Tech arrived onsite and began troubleshooting controls. Traced issue back to the unit locking out in the afternoon and the condenser fan motors overheating. The motors are exceeding their recommended max temperature during afternoon operation. Will recommend replacement for higher heat rating motors. Tech also cleaned the condenser coils to help heat transfer in the meantime.
