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

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?


I'd say yes. Whole problem could have been avoided by just buying
a new flex gas line. All the ones I've seen come with the appropriate
connector that screws onto the gas pipe. Or at least looking at the
connector for one of the flex lines at the store and buying the same
connector separately.
