Frigidaire wall air conditioner error code A5

[edcmaak11]

I was picking up my daughter from summer camp from a church.  One of the helpers was asking me about a wall AC problem.  He said the temperature wont go down with it set at 85 degrees.  I looked at it and it looked like an A5 error code.  I googled it and A5 means air sensor.  It doesn't have a sticker with the model number but looks like the link below.  Does Frigidaire make a universal air sensor?  Is it the one in the front of the AC by the grills after the air filter for easy access?  Appreciate if you have the parts location.  

 

I shut the AC off for like 15 mins and turned it back on, the compressor hummed but off after like 2 mins.

Just because it's throwing an air flow sensor code doesn't necessarily mean a bad sensor. I believe that sensor reads temperature. Not 100% because I have never had one of those sensors bad. If you compressor is humming then going off that's not a good sign. I would think 15 minutes off would be plenty of time to restart. May have a bad capacitor if it isn't starting or a locked compressor.

That's usually how it goes Most of the time they aren't worth putting money in to. I had an older Haier for a friend of my boss with a bad capacitor. I just got one from a local electric motor repair shop for hvac units and it worked fine. Saved him some money and got it running that day.
