Arrived on site, clients disposal in kitchen sink closest to window was not working at all when turned on. Gave client diagnostic options to find issue. After diagnostic, found the disposal to have a pneumatic switch to control on/off for disposal. Plugged switch into different outlet underneath sink where dishwasher is plugged into, and everything is working properly. I tested the original outlet for disposal and got “hot/ground reverse†lights on outlet tester. I have pneumatic switch/disposal plugged into other outlet that is working until electrician comes and fixes the other outlet. Having Bell electrician come and check it out Friday 10/22/2021 8am-12pm window.
