He told me the other day that the garbage disposal was broken, that there was nothing causing the blades to catch but it was just making noise and not doing anything when he turned it on. I googled it, went downstairs and 20 seconds later called him down. Flipped the switch and it worked just fine (actually, better than it had in the past year since we bought the house as it sounded kinda clunky to start). He was like "wtf how? What did you do?" And I showed him that you could put an Allen key into the bottom of the unit. Told him that it was sticking but it came loose with just a bit of pressure, and then I hit the reset. Glad it worked cause otherwise it would have meant the motor had gone out and at that point replacing the whole unit would have been more cost effective than attempting to repair it.
