Thanks for the positive input, yes the Fridge Defend is the only method to determine if there is a
Quality of Heat issue. Boiler operators would not be without proper '
state of boiler' inputs/diagnostics such as the Fridge Defend.
I am sorry that I am not monitoring these posts.
Thanks for contacting me Gary, here are Gary's stored Fridge Defend troubleshooting variables:
AtO = 208
AtS = 231
AbS = 299
tr = 013
OPn = 057
SHt = 000
SSH = 242
It took me only a moment once I had the troubleshooting variables to solve this problem. Gary confirmed that there was a bad crimp connection on the boiler sensor. The absolute maximum temperature of
299 is not reasonable, as Gary said the control tripped
13 times, and the boiler sensor was open
57 times.
It is important to zero these variables once the crimp connection is fixed so that down the road, if another issue occurs, these values do not give us false readings and mask the real issue.
Thanks for keeping RVing safe
The ounce of prevention that is worth one ton of cure and suppression.
