People don't repair appliances because the cost to repair has become much too high in comparison to buying a new unit.
Parts are too high. When a washer transmission is $250.00, and a new machine can be had on sale for $399 ... where's the justification?
Servicers charge too much for service. On top of the part(s) and labor to install it, there's a separate diagnostic fee, and often a trip fee.
Gone are the days when Mr. Washerman came by to fix a broken wig-wag pin with a (free) nail and $2 for his trouble. Or $6 for a belt and $10 for the service call.
Nowadays ... broken drive coupler? $40 part, $75 diagnostic fee, $120 trip & labor. That'll be $235 + sales tax. Thanks, kindly.
