Drywall noob here. 1955 home in Sacramento. I patched a bunch of cracks about 4 months ago but waited to repaint to see if my patches would last. Most did, but this part of the house just seems to keep settling, and this area cracked again so I opened it up. Many of the cracks had been patched before, including this one.

Given that the house continues to settle and I can't afford more foundation work (I've already done some at the back of the house), should I just keep patching or hang new drywall? New drywall will just crack too, right?

I've lived in my home for 3.5 years, and I think the furnace was about ten years old when I moved in. I never had any problems until last week when it blew a fuse. I replaced the fuse, and it immediately blew again.

What could be causing this? What should I check?

My HVAC is giving my thermostat the silent treatment. Thermostat tells the furnace to get warmed up. Nothing. Tells AC to cool it. No response. They were getting along great just a few days ago.

I swapped out the newer Sensi smart thermostat for the old dumb one to see if the thermostat is the problem, but still no response.

Could this be a loose connection somewhere? Where should I look? Could it be something else?

Sincerely,

A Clueless Homeowner

Edit: It's not the wires in the thermostat. I took the photo when I was in the process of swapping out the new thermostat for the old one. All wires were screwed in tight, and I have the same problem with both thermostats. Based on what a few folks have suggested, I suspect it's a blown fuse.
