Just installed a new board and it won’t even start.
When you turn the switch on, it goes directly to lock out. Red light goes out then it immediately comes back on.
Could it be another bad board?
Where are you getting the Boards? The problem Atwood had 2 or 3 years ago was they had no way to make 100% sure that the suspect boards were returned from vendors. That means dishonest people could get a hold of the suspect boards for almost nothing and then sell on the Internet or E bay. Most would work just fine a few times. We made sure we returned and purged our stock when Atwood had the problem and had Atwood send us the untainted replacement boards for our stock. You leave the switch ON. Disconnect the module plug from the board and plug in to test at the water heater. Doug
First board came from PDX in Oregon, second board came from Amazon.
The first board is Version D and the second is Version E. So something changed I guess.
What are you referring to when you say “plug in to test”. What do I plug in?
Update:
Installed first new board, new ECO and Thermostat and new wire harness.
Water Heater fired off and is working as designed. Going to cycle it a few times to confirm operation.
New wire harness eliminates the small plug adapter and both the old ECO and Thermostat tested good on the bench.
Only time will tell.
