Need some assistance please

Hey guys.. was home yesterday evening and noticed my temperature rising and the fan not blowing in the house. I was outside till 2 AM trying to figure it out and so far it's not the usual that I've found in the past.

What I have is a heat and air packaged unit outside. The only thing located in the house is the thermostat control.

The first problem I noticed was the blower was not pushing air into the house. I manually turned it to on and it still doesn't come on but the board in the video starts making a tone noise. I'm almost wondering if this board is damaged but am not sure on how to test it.

For testing of the blower fan, I pulled the black wire and hooked it on the front side of the contactor. It will work like this just fine. So while leaving this on, I noticed the compressor will kick on but the condenser fan won't. I tested the capacitor and it reads within specs. 5/45 uf so I've eliminated that. The next I did was hooked the condenser fan directly up to 240 and it runs fine.

I'm kind of stumped and needing some assistance. I'm thinking it may be this blower board but not sure. Can someone help me out with testing it further?

Well I got it going for now. Blower fan has to run full time but she's cooling. Guess I'll order the board and see if that fixes the problem.

Yup ,I'd say you need a new module.

most likely that was the problem

the contactor looks really burnt I would replace it at the same time

I'm trying to figure out the year model of this unit. If I'm reading this chart correctly, it could either be a 1981 or 2002. The house was build around 1981 but I was a young child so I'm not sure how advanced they were in these years.

Would anyone know if this looked more like a 81 or 2001 model? I'm hoping it's an 81 because if it is, it's time to replace in my opinion.
