In the event that you do not have a grounded outlet to power the garbage disposal, you will need to install one. Adding a grounded outlet may cost as little as $5 when existing electrical wiring is placed a short distance away, plus an additional $75 for the electrician's labor. If a new grounded outlet needs to be added and electrical wiring does not yet exist, it will likely cost around $90, depending on labor and parts. If your project requires the addition of a new switch and wire, plan to spend an average of $5 to $10 on materials, plus about 30 minutes of labor at an average cost of $75 an hour.
Garbage disposals can range from $70 on the low end to $380 on the high end -- and generally speaking, you get what you pay for. A less expensive unit is likely to produce more noise, require more water, and clog more easily than a higher-end model. Likewise, a more expensive unit will be faster, quieter and less likely to malfunction than a lower end model -- and it will be lighter-weight and offer greater capacity as well. The average cost of a garbage disposal installation with a one-year manufacturer’'s warranty is $185. The average amount of time taken to install a garbage disposal, including cleanup, is three hours. The hourly cost for labor will range from $20 to $40 -- $28 on average.
Make sure that there is power getting to the unit. Garbage disposals have an independent cord that is plugged into a wall socket beneath the sink. Unplug the disposal unit and plug another small appliance, like a desk fan, into the wall socket. Turn the appliance on to see if it works. If it doesn't work, check the breaker panel. If the breaker is flipped to the "On" position, there is an electrical problem on that circuit, and an electrician must be called in.
You should first find out whether only the disposal is broken, or if the power has gone out completely in the areas near your kitchen sink. Try resetting the circuit breaker that leads to the kitchen, or replacing a fuse if you have an older electrical box. If the garbage disposal makes no noises at all when you flip the switch, you might also want to check under the sink to see that it’s plugged in.
