Weber BBQ + cover (Northwood HA6)

Weber Model 210 gas barbecue - 8+ years old has not been used a huge amount ( possibly several dozen times in total ) and cover is on almost always after use. In most respect it’s in reasonably good condition, but (1) grill grates/cooking grids need some cleaning/TLC; (2) I’m not sure if the thermometer works; and (3) one of the ignition wires has become disconnected. So it needs an owner with a bit of patience and DIY skill.
Shelves on each side can be lowered.
There are two grill grates each with its own separately controlled burner. There’s also a raised grill grate, that you can use to keep things warm, or for a bit less heat: it is lifted up as you open the lid
