Ac Goes Warm After A Few Hours
ac will run perfect for a couple of hours then it will start to blow non cooled air while the power light on the inside head starts to blink. When I go outside and manually spin the fan by hand the ac starts to blow cold air again. This will continue every so often. When I turn off unit for a couple of hours and restart it works perfectly fine until running for a few hours then it all happens again, like stated above

1. Air conditioners will stop cooling if the outside temperature drops below 60F because the unit thinks it has done its job. If that's your situation, your best course is to open and window and turn off the A/C.
2. If the above doesn't solve, you'll need to consult Sanyo: use the contact information here--https://www.contacthelp.com/sanyo/customer-service.

This is most likely caused by the fan motor or the thermistor control assembly. Rather than just replace parts I suggest you contact an AC tech to troubleshoot the issue.
