Customer tried to install his own thermostat. Plus, additional problems found in the attic.

I am in a vacant house, two-story, one system, got vents in the ceiling, and right now I'm trying to turn on the blower, and I've got nothing, so let's look for that air vent. Nice access, I like this. All right, we've got 2008 train, can hear the transformer humming. The pan, the pan has a crack in there. What I'm seeing, the pan needs to be replaced. Plastic pans may not rust, but they tend to break all right i'm gonna go get my tools and i'll be right back up here it looks like somebody has changed his thermostat i see they got orange on b yellow i do not see a common this must be something somebody bought at like Home Depot not sure if y'all can see what i'm seeing blue is probably gonna be my common all right let's um i'm gonna pop cover on the air handler i'm imagining we have a blown fuse and uh i'm not sure this is a heat pump thermostat i do have a b and a oh but no option for emergency heat so uh we'll see all right let me see where's my fuse gonna be i can hear that transformer humming this is one of those boards that tell you the CFM by the flashes i'm looking for a fuse this is i don't carry a fuse like this we have i'm going to put in a different kind but this thing's solid white not check to see if it's any good all right i'm gonna go get a different kind of fuse some wire connectors and uh go down there and read about that thermostat and putting the ends on it we need to use one of those automotive fuses you want ends with plastic on them because uh they can touch and if they touch the fuse is no good we got 24 volts i can hear it let's put this on real quick and i'm gonna check these terminals down there not a great idea to put those in the bottom of the air handler all right let's see if we uh between blue and that looks like red right there 28 volts all right so we are fixing to see about that thermostat it says right here on this box it's compatible with heat pumps without backup heat so i'm gonna have to put on a new thermostat Gree next we have programmed this thing it's fairly easy to do just follow the instructions we're gonna make this non-programmable fahrenheit and here we go two because it's a heat pump air to air heat pump reversing valve oh and cool so that's right first let's see if the blower will come on i think i heard it those variable speed motors run really slow and it's just a call for fan yeah it's running now we gotta check it outside you know somebody does a change out on this they gonna love that right there all right it just ramped up blowing cold air homeowner is going to do the right thing place this pan but he wants me to he wants me to go ahead and put in the SS2 right now i just killed power i'm just gonna break this right here that's with me one turn so if you notice this drain is just slightly higher than the other one these have to be straight up and down off to an angle that float won't float you know what this floats no good whatsoever so i'm gonna discontinue it until we come back up and do this pan and i'll see that lovely all the this thermostat wires feels like i can move them but they are going in on top of that so i'll return to do the pan that's something i'm gonna have to address all right we got that the flux switch hooked up that's just that's just open to attic air i'm not real sure how that did not cause a trouble call
