1.) Brother purchased Whirlpool Estate washer (TAWS700RQ3) and dryer
(TGDX640PQ1) set for $200 on Craigslist. Seller assured him that both
were in excellent condition.

2.) At home, washer worked as expected but no heat from dryer.

3.) Called gas company to check hookup. Gas tech said dryer had wrong
adapter for hookup (from flex gas line to dryer gas pipe).

4.) Purchased new adapter, still no heat.

5.) Replaced solenoid coils. Still no heat.

6.) Paid appliance repairman $60 to diagnose dryer issue.

7.) Repairman said no gas was getting to dryer and would need to
replace gas burner assembly. Cost would be prohibitive.

8.) Sold dryer to repairman for $20.

As repairman was moving dryer to his van I asked for the adapter that
my brother had purchased. Repairman looked at it and said the adapter
was suitable for a gas grill, not a dryer. Said that probably was why
there was no heat. Repairman would not return the dryer since it was
sold.

Shouldn't his troubleshooting have determined that the adapter was the
wrong type?

Yes.

Note: Brother purchased another used dryer for $125 (with 90 day
warrantee) that works.

Yes. He should have returned the $60 and the contract of sale was void due
to mutual mistake.

Or fraud.

Do you YELP?

Surprisingly, the repairman emailed me asking for a good review on
Yelp and Google. I informed him of my dissatisfaction with the way the
adapter discovery and dryer sale was handled. Here's his email reply:

I have not yet had an opportunity to take your dryer to the junk yard
and it is fully intact still on my truck. I will gladly bring it back
to you so that you may reassess it your self, and get the twenty
dollars.

I'm not sure whether he's offering the dryer back or if he's just
offering us to test that a compatible adapter would have worked. I'm
pretty certain that the dryer won't be going to a junk yard. I told
him that we're done and I wouldn't be writing any reviews, positive or
negative.

I think the first mistake was paying money for a used dryer.

I'm sure there was nothing wrong with the dryer. It just needed a
compatible gas line adapter.
