This was another annoying hold up. We had a dryer with a 4 prong plug. The house had a 3 prong outlet. The big unknown was had it been retrofitted at some point. If so then the fourth wire (a second ground wire introduced for fire safety) would be in the wall. If not the would have to run a wire from the circuit breaker to the dryer outlet box, which are of course at opposite ends of the house. That wire also apparently costs $20 per linear foot WHOLESALE. Oh joy.
Well I’m happy yo day that this is the first thing that ended up being the cheaper option. Whew. The wire was there and after a few weeks of rapidly growing dirty laundry piles we finally had our washer and dryer running.
