I have a Macdonald model 77 insinkerator and it just stopped working. What could be the issue? and is there a manual on this? thank you
Does it hummm? They don't make a model 77, So if you look again, Maybe we can get a model. Does it have a Aqua-saver controller?
Using Google, I found reference to a Model 77 as being a home unit. We really don't deal with home appliances here.
I also found a broken link to InsinkErator's website to a model 77. My guess is that they quit making them awhile back.
All disposer's have an overload switch that trips if they get jammed. Usually the reset button on the bottom. When you find and press it in, if it clicks, then it was tripped. You can try running it, but if it's still jammed, it'll just trip again.
You can call someone to fix it. Plumbers and technicians have tricks for unjamming most disposers. However, if it really badly jammed, the cost to repair it might surpass the price of a new one. With it being a household unit, you probably won't be able to get repair parts for it.
That's why I couldn't find it. Domestic.
