The garbage disposal motor was burnt up last time I was here. I tested everything and they had 120 volts with the switch on and with the switch bypassed. The customer changed the disposal and then discovered the switch was not energizing the disposal every time. We couldn’t tell last time because the disposal being burnt out. So this time I re deviced the three gang box next to the sink. 1 switch for the garbage disposal. 1 switch for the sink overhead light. And a receptacle. Customer has a 30 day warranty
