For a moment, consider repairing a disposer. Is this wise? First, there is virtually no chance that you will stock any of the necessary repair parts. It is also unlikely that any supply houses would stock the needed parts. The parts don’t sell because few technicians repair disposers. As a result, waiting for parts will delay the repair for days, and probably weeks.
In the mean time, the customer may be without a sink. How many customers are going to tolerate the loss of their kitchen sink for days or weeks? None.
One alternative is to install a temporary disposer. But labor rates make it impractical to install a disposer twice.
Because of the importance of keeping a kitchen sink in service, a disposer call must be completed in one trip. Saving the customer money is of secondary consideration. Install a new disposer and get the job done.
Don’t even consider getting involved in the five disposer motor repairs. If the failure occurs during the warranty period, let the factory technicians do it. Otherwise install a new disposer.
Never, ever, take a disposer apart. Always replace it. Recently, we reviewed the ICS course kindly sent to us by a student. We looked over their detailed approach to disposer repair. Numerous pages were spent on disassembly, repair, and reassembly. In reality, disposer repair is not generally practiced in the industry.
