Is it worth replacing?

If you're keeping it
A clothes dryer like the LG SWWG504 is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 685 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 514 of 639 certified dryers for running cost, the LG SWWG504 is also worth reading with a caveat specific to this category: the methodology page explains why ENERGY STAR's own combined-energy figure for dryers can overstate the electric bill impact of a gas model.
