Yep just not worth it unless you have some kind of specialty in this case if you had worked on appliances regularly in the past. I sell all my appliances working or non-working for $25-$100 to guys that fix them, test them, clean them and then sell them. My job is to get stuff and turn a profit not to sell to the end user. I sell appliances full price every now and then but, only when it is convenient. Testing, cleaning, and then selling takes a lot of time. Better to sell to the same guys and have an instance buyer.
Wow Im surprised you got $40 for a broken electric drier. I can barely sell a working electric drier for that much. Around here everyone wants gas.
You made the right decision
