- thanks for the thouhgts ... this is a new board as a function of the c7 76 error code indicating bad control board or connectivity between remote control and control board. I've cut the remote control wires and both ends, re-stripped and reconnected with no change in error conditions. Installed a new control board and reattached remote control and received error -0 82, which I've been led to believe means that the new control board needs a bit of configuration for either altitude or gas type; e.g., natural or LP. I apte the help, but it didn't help solve the problem.

you can call rheem customer service at 18004328373 you will need model and serial # before they will help you .the actual problem by what the error code is showing on the display is as follows: the main circuit board is not proving power to the thermostat so its showing this error.the main control board needs replacement.but many times it gets reset by doing this as follows:-- disconnect the thermostat/digital display from the main unit. This is fairly simple to do by removing the front panel.then again reconnect after some time and check out. --------- This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.

I have seen your problem and I do not know if I can help but thought I would give you some ideas. Now I know you are aware the error is for wrong gas type. Are there any jumpers or tiny switches on the PCB that would allow for adjustments to the gas type? Also I would check the actual thermostat...There might be a switch inside the thermostat unit that can be adjusted. And make sure that the PCB that you installed is not for LP gas and creating an error. I don't know if you have already been given these ideas.
