She knew about the service call fee. The 4 On Your Side Investigation found that’s a common fee. Consumer Investigator Jodi Brooks called around to try to get an estimate from private plumbers for a garbage disposal replacement. None of the businesses we called would give an estimate over the phone. All of them wanted to look at the situation before committing to a price, and all wanted to charge a service fee to come out. Brooks found only one plumber who would come out without charging.
Run cold water while the disposal is on. Keep disposer and water running for 30 to 60 seconds AFTER the waste matter has cleared your drain. The waste still has a distance to go. Cold water keeps the motor, bearings and shredder assembly from overheating. It also lets the waste go down easier because the water is pushing it down. Don't use hot water, because it can melt fat and allow it to re-solidify as a blockage further down in the drain.
Your garbage disposal gasket is the top rim where the rubber seal mounts to the flange.  If your disposer is leaking from this area, the cause could be a leaky gasket.  Gasket leaks can have several causes: ageing gaskets can develop leaks; long periods of disuse can dry the gasket and cause it to leak; if your garbage disposal was removed and then replaced, the gasket may have been improperly sealed; if the gasket is not locked evenly on all three sides, it will leak.
If the disposal is plugged in and doesn’t need to be reset, then you should check the circuit breaker. The breaker could be flipped, which would mean your disposal isn’t getting power. If that’s still not the problem, then either the outlet is dead, the circuit breaker is malfunctioning, or the disposal needs to be replaced. Check the outlet first by plugging something else into it. If the outlet works, try replacing the circuit breaker switch. If that isn’t it either, you have to replace the disposal.
Dispose orange peels, or any citrus rinds, to freshen the disposal and keep it smelling clean, but cut them into slices first as large pieces of citrus peel, e.g. half a lime, can jam a disposal. You can also use pieces of citrus fruit that may be too old to consume, as long as they're not too spoiled to smell nice. You can freeze these pieces first, if you wish.

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.
