Lennox is generally pretty 'tight' about supplying info about their systems on the internet... and I don't have any data on them myself.
Generally if there is a rollout fault it would indicate that there is a dangerous situation going on... meaning exactly what the name of the sensor implies; that there is a 'rollout' of the flame from the combustion chamber.
It should ALWAYS be believed that the sensors are FUNCTIONING the way they were designed to function. That there actually IS a problem with 'rollout' and the sensor detected it properly and shut the burner down before your house burned down.
What needs to be done at this point is that the system be examined for proper combustion, blockages in the internal flue passages in the unit, etc etc ... and if a problem exists it must be corrected before replacing the rollout sensor and turning the boiler back on.
Associated with the obvious fire hazard is one that is INVISIBLE... CARBON MONOXIDE. When there are problems of this type it is HIGHLY possible that there could be elevated levels of CO in the home, so PLEASE check your CO detectors... or install them if you don't have any. We don't want anyone waking up dead on our watch.
If you are unfamiliar with gas burning heating appliances, I would highly recommend that you schedule a technician to examine your system. In view of the obvious SAFETY factors, this may not be a job for DIY.

I have the manual with me and the manual and the panel say two different things. The manual said it was the rollout switch but the panel said it is the Primary / Secondary switch open. The furnace will come on and run fine for 5 or 10 minutes then go to this fault code for another 20 minutes then repeats. Any suggestions?

hi mckee –
I know nothing but I was looking at the GHR26 manual and I noticed on page 8 Table 1, for some reason they put the second LED (DIAG2) in column 1 in the table, and the first LED (DIAG1) in column 2 in the table?
Rollout is [DIAG1 = ON and DIAG2= SLOW FLASH]
Primary/Secondary Open is [DIAG1 = SLOW FLASH and DIAG2= ON ]
So if you look at Table 1 and don’t notice the LED order is DIAG2, DIAG1 in the table, when you read the LEDs you would interpret “Primary/Secondary Open” as “Rollout” and vice versa?
Maybe I’m wrong but it sure looks that way to me. Table 1 is only for model GHR26-1 with the EGC-1 control board, and DIAG1 is on top of DIAG2 on that board. But even so , the top LED is labeled DIAG1 and the bottom LED is labeled DIAG2 on the board. So if someone reads the LED’s and looks at the table seems to me they could easily wind up with the wrong interpretation.
And maybe that is all totally irrelevant?
Anyway, good luck!
