Sounds like it could be a dirty or bad flame sensor.
When the burner lights ,there is a flame sensor in the flame and it is suppose to sense the flame and send a signal back to the control board which will keep the gas valve open, if it gets dirty or is bad it doesn't send the signal back to the board and the board will shut the gas valve off and after three tries it will lock out the furnace and you have to reset it to get it to work again.
The flame sensor looks like a wire and it's in the flame usually it will get gas deposits on it, then it won't work.
You can clean this sensor with an extra fine piece of steel wool, but before you attempt to do this DISCONNECT ALL POWER TO THE FURNACE.

Hi,
no just repalce all the covers and then cycle to power to the unit and it should take off and go...be aware that the t-stat could take five minutes or so to recycle and star the unit also..

Call Rheem
1-800-432-8373
They might ask you to contact the installer. If you installed it yourself ... well that is problematic. For example if vent condensation drain was not installed correctly, the condensation can drip down into the unit causing acidic water that will shorten life of heat exchanger.
Make sure there is affordable qualified service in your area before buying tankless water heater.
Avoid wallet thickness error.

http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Don't forget to keep up with yearly maintenance, and tankless cannot be exposed to more than 11 grains hardness in water.
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf
And if you need a service manual for your Rheem tankless, well that is problematic since Rheem does not have service manuals ... might try reading Bosch or Bradford white service manuals.

The 3A fuse on the white wire keeps on failing. what could the reason be?


Most likely bad PC board.
The fuse stops damage such as fire, but the PC board probably needs to be replaced.

Other causes might be wrong polarity on 120 volt outlet, use a circuit tester to make sure the hot, neutral and ground are correctly connected.

No power to unit


Copy following link for tankless troubleshoot resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#fuse
Tankless are not protected from surge, but there is a 3-5 amp glass fuse located on circuit board.
Check outlet with circuit analyzer, and multimeter

Rheem water heater rtg95dvn keeps blowing 3 amp fuses


Not for sure what your root cause was and I know it's a little late but I just suffered this same exact scenario on the same water heater. Storms came through, power went out, power came back on and the water heater keeps blowing the 3 amp fuses now. I removed all the cables and plugged them back in one at a time. When I plugged in the Fan Motor connector the fuses blew. Installed new fuses with the connector out, the Fan Motor was putting out 150 VDC through the connector port (on main control). I pulled the control from the unit and Q1 is visible blown and disintegrated on the control board. Obvious control design issue. I've ordered a new control and will put a surge protector on the heater now when the new control comes in. Very disappointed that this was not caught in controls testing within the manufacturers facility. New control is not very cheap. Half the cost of a new Heater. Hopefully the Fan Motor survived the high voltage with the fuses blowing. I'm putting this here for anyone else that suffers the same issue on this water heater or the Richmond equivalents as they use the same control.
