Problem with a Rheem, bet you can't figure it out

[truck12]

i DIDN'T READ EVERY POST, SEEING THERE ARE A LOT. ON A 95 DEGREE DAY, BOTH STAGES WOULD LIKELY BE CALLING FOR COOLING AND IN THE MIDDLE OF THE NIGHT, ONLY STAGE 1. POSSIBLY SOMETHING WITH FIRST STAGE ONLY. IF YOU WANT TO FIGURE THIS ONE OUT YOUR GOING TO NEED THE CUSTOMERS HELP. IF HE CATCHES IT LIKE THAT, HAVE HIM GO TO OUTDOOR UNIT, FEEL THE PIPES. GATHER AS MUCH INFORMATION AS POSSIBLE, OR SET UP A TENT AND SPEND THE NIGHT LOL.

Now I see why no one does does follow ups, posts just die out and no one knows what happened. The problem is solved by the way. When I say I can duplicate a problem that means I've narrowed it down to a specific part. Thats what I did and replaced the part. So far no call.

you look for spider webs on back of board ?

i guess u cant now .... you replaced the board

First one I ever replace had a lizard fried under it. It's body fluids ate the circuits until one opened up and shut something down.
I do a visual check on everything.
