I ran out of hot water while in the shower yesterday. I could not relight the pilot in the water heater. I thought I had a water heater problem. When I did a load of laundry and put my clothes in the dryer that is when I realized I had no gas because the dryer would not get hot. I went outside and saw the gas valve fully on and then I saw the Earthquake-actuated Automatic Gas Shut Off Valve had actuated by showing a red bar in the window. I then had to shut off the gas and using a screwdriver to turn the Reset shaft 105 degrees until a green bar shows in the window. I turned the gas back on and went inside and started the dryer and re-lit the pilot on the water heater. I now have my clothes drying and hot water.
