Protecting what you have
Whether or not the LG DLGX7901E ever needs replacing, a repair is the more common failure for a clothes dryer, one a protection plan budgets for ahead of time.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. Ranked 507 of 639 certified dryers for running cost, the LG DLGX7901E 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. Whether a repair or a full replacement dryer makes more sense once the electric bill is this well known is covered in the guide to when replacing one pays off.
