Customer garbage disposal wasn’t turning on at all. Upon arrival. I diagnosed the issue and saw that the air switch line wasn’t connected and after I plugged it up, it was working, but the air switch itself was giving issues turned it on or off sometimes so I’ll let them know that I recommend replacing the air switch and also Replacing the garbage disposal due to age, another issue the outlet for the garbage disposal was reading a open ground, so I have electrician coming out to inspect the electrical, after I connected the air switch cord and plugged in the equipment. The disposal was turning on, the air switch itself is having issues turned it on and off on top of it wasn’t plugged in as was , customer wanted to have the electrical inspected first before going with replacing the disposal and the air switch
