Tried to take a shower last night & had cold water. I may be a girl, but I know enough to check the pilot & it was out. I tried lighting several times following directions with no luck. I cleaned off burner & thermocoupler with an old toothbrush and tried again. Still no luck. There's not even a spark. It doesn't light at all. Yes I am holding down the red button & yes I turned down temp & yes I turned knob to pilot. No my furnace is not on at the same time, but I checked it & it does go on & heat up. I checked the outlet & there is power. What's left to do? If it were the thermocoupler, wouldn't the pilot light & go out? Should I hear some sound of gas moving (no guy jokes, haha)at least a hissing sound when I hold down the button? Please let me know if anyone has any safe ideas. The water heater is a Rheem SG40 installed in 2000. 7 years ago a friend installed a new thermocoupler becuz the pilot light wouldn't stay lit. But at least then there was a light that just wouldn't stay on. Thanks for any help!
